Lots of Learning: Match Results, Mystic Precision Bipod Review, and Leupolds Gold Ring VX-6 7-42 x 56mm Competition Scope with CDS

Testing new gear in a long range match.

I had an interesting match last Sunday (28-May 2017). In my previous article here I announced the intent to test some new gear in a match.  I learned a great deal about changing gear before a match, but the biggest takeaway is: If you change gear and don’t practice with that new gear at competition distance, you should be prepared to have a few accuracy surprises that happen once you start punching holes in paper.

First Impressions: Leupold Gold Ring VX-6 7-42x56mm Competition scope with CDS

First things first, the glass is just gorgeous to look through.  The morning of the match I had it dialed up, but as the day went on and the mirage started to intensify I had to back off a bit to 32X.  I also realized that I have some additional adjustments that are necessary for eye relief when in the prone position.

Learning about the impact of new gear: Leupold graciously supplied rings for our testing that would mount to any rifle for us to test as long as it had a picatinny rail.  The particular issue with my rifle is that I did not have a high enough comb nor adjustable comb to accommodate the ring height.  I knew this going into the match but honestly didn’t think that it would matter that much, but it definitely did.  The difference or variability  in cheek pressure on the comb had a huge impact elevation control and lead to uncomfortable body/head positions and a poor score.

First Impressions: Mystic Precision MPOD Bipod

While zeroing the rifle the bipod was like a rock, on the line at distance, however, my “squeeze bag” style rear rifle rest was not cutting it.  In order for the bags to work effectively you need to apply consistent downward force with your cheek and squeeze the back to it to remain stable.  If you can’t apply consistent pressure with your cheek, then having a repeatable position is difficult, and my score’s definitely reflected that; my worst for the day was below along with my typical score from last year.

Score last year with original set up.

Score with different set-up (Different SCOPE/BIPod).

I will note that at the time of the string of fire, a shot was marked as a miss, but following my string and talking to Art Lamb, who was scoring for me, he informed me that one of my rounds was subsonic at 600 yards and he later identified the impact in the white portion of the target, so not a miss, but perhaps a 5 or 6.  Not too happy about that; I did notice that my barrel was getting a bit hot from the quick string of fire, so I don’t know what happened here.  My next purchase is a good old kitchen timer to make sure I don’t go too fast and heat the barrel up too much.

On a humorous dad note, my wife called me and informed me that my mother in-law was at our house with the kids needing to put my youngest son down for a nap.  The only problem was that I locked all the doors and she did not have the key.  Rather than breaking into a fit of twitches after my horrible match, I calmly let it roll off my shoulders and trekked 4 miles down the road and let her back in.  It’s good to live close to the range. Looking back and doing some diagnostics on the poor match, I realized that I should have changed bags over to one of my fixed rear sand bags with the bipod.  The toe of my stock is angled so that elevation corrections can be as simple as moving the bag fore or aft of the buttstock.  We always learn.  I’ll be better acclimated to the new gear next time.  Next up; a barrel swap will take place to the new Shilen 6.5 Creedmoor Match Barrel and we’ll do some F-Open work with a front rest for a match on 17-June.  I love the Savage Barrel Nut!! It’s so easy to swap barrels!

Until next time…..

See you on the range!

Memorial Day, the Mystic Precision MPOD Bipod, and the Leupold Gold Ring Competition Scope for F-T/R Match

First, a reminder for this Memorial Day weekend, which is likely to be full of barbecues, parades and perhaps a frosty beverage: Never forget!  Just a reminder dad, I will never forget.

Image courtesy of Associated Press

My kids and I are looking forward to the parade this Memorial Day weekend to honor our soldiers, but it means so much more than that.  I did not serve, but my father along with the rest of my family, has a rich history of putting on the uniform for this country since the American Revolution.  I take these holidays seriously, as that was how I was raised.  With my kids, I do my best to explain the meaning of remembering those that, when their country called on them, ran towards harm instead of away from it.  Some of whom made the ultimate sacrifice.  It’s because of them that I get to punch holes in paper for fun and nothing is headed back in my direction.  Thank you, thank you, thank you dad and those who have served this country.

Mystic Precision MPOD Bipod

Load testing will continue with the Nosler bullets, but in the mean time, I have a match coming up this weekend and will be using my current match load of the Sierra 175 TMK’s which I have to use up.  I started long range rifle competitions using my standard Harris S 6-9″ Bipod.  It worked well to start out, but one of the downsides to using this basic bipod was that you couldn’t track your shots and the bipod would often sink into the position (dirt/grass/sand) which lead to fighting elevation changes in the middle of a string of fire.

I decided that it was time for an upgrade for future competitions. 

After a lot of research on F-Class bipods, I settled on an economical lightweight design from Mystic Precision.

It’s a Canadian company, but the bipods are actually manufactured right here in the USA,  at Evolution Gun Works in Quakertown, PA.  I have my first match this weekend.  I will report back on what the differences are with this bi-pod.

From Mystic Precision’s website:

MPOD Design:  Make a super light bipod with the stability and tracking of a pedestal rest

A winning design: Winner of the 2013 Individual FTR World Championship used the MPOD.  Multiple NRA records in Team and Individual set.  Several Members of the US National FTR team currently shooting with the MPOD

Improved geometry to reduce the effects of torque during recoil for consistent tracking and follow through despite the chambering. Has been successfully used on larger caliber boomers including the 50BMG

Easy to operate with large range of movements to account for varied terrain.  The lowest height is 4 1/2 inches suitable for bench work and raised berms when shooting prone. At full elevation, you have 7 3/4 inches to the mounting lug.  This range is wider then the Harris 6-9 bipod.

Cant feature is now added for quick leveling on uneven ground.  And the Cant will not shift during recoil as is common with most other bipods.

Easy to install and remove – Solid with great repeatability and accuracy potential.

Stability increasing with increased pod height which is opposite to a number of designs.

Keep finished weight as low as possible – 12.8ozs installed, yet strong enough to support heavy rifles and big boomers.  Easily supported rifles weighing 50lbs.

I’ve also mounted and plumb leveled the Leupold Gold Ring VX-6 7-42 X 56mm scope with 34mm tube for it’s first test.

https://youtu.be/t9ocquk0m7Y

I am excited to have the target fill up more of my scope at the higher magnifications.

I’m used to no higher than 25X magnification and First Focal Plane reticles that obscure the target more than necessary, so this should be a real treat.

Having that much magnification can be a real benefit if mirage isn’t too bad.  Local range conditions for the match look good, mid 60’s and 2 mph winds from the south.  We’ll see if that holds; field conditions could be completely different.  I’m going to re-zero and confirm my come-ups for dialing to 600 yds the morning of the match.
I will post my scores for this weekend’s match, share a few thoughts, and post a few photo’s of the bi-pod and scope mounted at the range.

Have a great Memorial Day Weekend!!

See you at the range.

Sight- In with Leupold VX-6, Nosler E-Tips and TC Pro-Hunter for Russian Boar

I moved my best scope, Leupold’s Gold Ring VX-6 3-18x44mm to the TC Pro Hunter using Weaver Grand Slam style bases and a quick detach ring.

Shooting in very cold weather created a situation that I could not control with the levers as they were hard to tighten and became loose at the range at 15ºF, and could be banged loose on branches in the heavy woods.

Accordingly, I went to my NH  Bass Pro shop and found Warne Scope Mounts in Steel (Made in the USA) for a 30mm scope tube. It was almost impossible to find out of regular hunting season… but I did.

It is a split ring in right and left halves.

Product Details

The directions were great as I already had a Wheeler Fat Wrench with a T-15 tip. All I had to do was set the torque to 25 in-lbs for the screws and I was done. Cost $59.00 but I did not shop around as I wanted them now.

What I had not purchased for the VX-6 was scope covers, so I went ahead and fitted the scope in the BassPro store with Butler Creek Flip Open Scope Covers. The front 44mm lens took a 53.3mm cover.

Butler Creek Flip-Open Objective Scope Cover, Size 31 (1.998-Inch, 50.7mm)

and the rear lens took the 42.2 mm lens cover with the red lever.

Product Details

 

I have had great success with all  my other scopes with Butler Creek covers but it is best to bring your scope with you and fit it right there.

I tested the E-Tips, Scope, Mounts and Covers today at the range and was shooting off the shelf Nosler E-Tips at 100 yards. I was  pleased as punch shooting between one and two inch groups. At 50 yards, where most of my shots at Boar should be, I wasn’t gonna burn more powder and bullets to split hairs.

 

If you get snow in your barrel, what then? Use a single piece of elect tape to cover your barrel muzzle or buy latex finger cots at your local grocery store or pharmacy. Like a small condom for your rifle barrel.

Method #2 bring a bore snake in your backpack if you have to clean the bore in the field due to mud or snow.

My TC all Rigged up

Bring on those ornery Russian Boar tuskers…

TC Pro Hunter- Excellent Trigger Job by 1GUNSHOP.COM by Ed Hale

Formerly bellmtcs.com now 1gunshop.com  who deals now in a wide array of technical gunsmithing, firearms, archery and so much more outdoor gear. A veritable Trading Post On-Line.  The lowest prices anywhere says Kurt Bellm the owner.  Now to the Trigger Job.

As I said in an earlier article, I was having difficulty installing the new lighter Trigger Spring so I sent the core frame (without barrel and stock) to Kurt Bellm in Colorado, owner of 1GUNSHOP.com. Note: The frame is serialized and must be sent via FFL.

Not only did he set the new Trigger spring but added a better custom firing pin and drilled the trigger guard, installing a trigger over-travel screw.  I asked that set the trigger spring at between 3 lb  and 3.5 lbs. My tests show it now at a perfect 3lbs. 5 oz.  I went to the range today to see how the trigger, firing pin and trigger over-travel screw worked and was elated at the crisp trigger, The dimple of the firing pin on the primer was perfect. Oh and for a few dollars more he recommended the 1x Over size Hinge Pin which is 0.0005 more than the current stock pin and will increase accuracy.

Honestly, If I could have installed the new spring, there was no assurance to hit my set goal either, it would have been approximate. It may have even been in the 2. 5 lb. category for all I know and too sensitive for hunting. So sending it back was a more a blessing in disguise. I called him on the phone more than a few times and he was very helpful.

Further that he works on so many T/C’s that he has not only more knowledge on T/C frames than anyone outside of the company but customizes indestructible firing pins, and creates a trigger over travel stop screw besides having the best of all the T/C springs and created the Over Size Hinge Pin to tighten the often looser hinge action. Loose side to side movement is eliminated with the new pin and accordingly improves accuracy from shot to shot.

Thanks so much Kurt!  If you need some TLC on your T/C see 1GUNSHOP for the solution and check out the Website and all that they offer.

New BELLM Trigger for TC Pro Hunter -update

UPDATE : I had trouble installing the new spring for the trigger so I am sending the frame to BELLM to do the work.

As  most of you know, I tested the TC Pro Hunter 50 cal. Muzzleloader/30-06 Springfield Rifle Combo this summer and fall…and I bought it! The cheek rest and ammo pouch is an add on of mine.

I love the combination as I can now buy barrels for shotgun and other calibers for it. The only thing that can be significantly improved upon is the trigger. So I ordered the G2 kit below from the new website. http://1gunshop.com/catalog/?ret_id=1485279

G2 Trigger Job and Spring Kits

I want the trigger pull in the 2 1/2 to 3 1/2 pound range so Kurt from the 1gunshop set me up for it. The kit should be here soon so I can install and test it before my Russian Boar Hunt.

In addition I will test the trigger with Nosler’s 30-06 Springfield 168 grain E-Tip that Zach Waterman of Nosler is sending me.

along with Leupold’s VX-6 zoom scope. It has a lighted crosshair too…

Good Hunting!

Savage Upgrade and Barrel Swap for NRA Long Range Target by Jason Hale

jason

After some nagging from my dad and carving some time out away from work and family, I finally got around to writing this article…..

I’ve long since been bitten by the long range target and hunting bug and now own 2 savage 10/110 FCP rifles chambered in .308 Winchester and .300 Winchester Magnum cartridges.  Upon seeing the accuracy potential of the .308 at the Sig Sauer Academy “Reach for a thousand”  1000 yd course a while back, with bone stock, I decided to purchase some upgrades to convert it to a long range rig.

The initial upgrade was the JP rifles AMCS chassis system, and then mounted some new glass (Vortex Viper 6-24x FFP).  See photo below by author.

Jason article Pic 1

With the added weight it was not suitable for hunting, but if I wanted to lug it around the woods, I could always return it to the OEM HS Precision stock and head out into the woods.

 

Since the stock upgrade, I’ve been looking out for any precision rifle series matches in the northeast, and haven’t found one yet, so I’ve taken to NRA F class target shooting.  Following the stock upgrade I entered into my first F-TR match and didn’t do half bad.  So after that, I committed to myself to enter into every match I could.  I set out to research a bit more about barrel upgrades I could do to make it more suitable for F-TR.  I was drawn to the inherent versatility of the savage barrel nut system, and dreamed about match grade barrels, but never had the courage to pick up a new one until I skimmed through a favorite website (Northland Shooters Supplies (NSS) website: http://northlandshooterssupply.com/).  I looked over their offerings with respect to target barrels and gave them a call, 15 minutes later I purchased my first 28″ button rifled match grade barrel made by Criterion Barrels . http://www.criterionbarrels.com  Five days of ground shipping later, I had that handsome barrel in my itchy hands.  While I was waiting for its arrival, I decided to clean the original barrel, oil it and prepare for it’s removal.  I purchased all of the re-barreling tools some time ago anticipating this activity happening at some point.

 

Jason Article Pic 2

 

  1. Savage action wrench from NSS
  2. Savage barrel nut wrench from NSS
  3. Savage stainless barrel nut and recoil lug.
  4. Chamber GO/NO GO gauges from Pacific Tool and Gauge. (absolute must for setting headspace properly)
  5. 1/2″ Torque wrench (make sure you calculate torque correctly accounting for extensions from the torque wrench head that increase lever length.)
  6. Never-seize (not seen in picture)

With this kit, I can re-barrel my action with barrels chambered for  .243 Win, 308 Win, .358 Win, .260 Rem, 7mm-08, and the .338 Federal cartridges.  Not bad for versatility, I’d say!

After installing my action into the action wrench and putting the wrench into the vise, I slid on the barrel nut wrench and with deep breath and a breaker bar easily loosened the barrel nut.  I was surprised at the ease of barrel removal reading of all of the horror stories from the web forums.

Jason article Pic 3

The critical part of re-barreling is setting the headspace correctly.  As I learned while reading about this swap, and thankfully not by experience, it is imperative that you remove the ejector plunger before you insert the headspace gauge, unless you fancy large gouges in your pretty chamber; not me.  Step by step instructions recommending the same can be found throughout the net as well as the fine folks at NSS.  One point to note, you don’t want the barrel to rotate as you torque the barrel nut and jam the go gauge in the chamber, you may end up with something slightly shorter than SAAMI Sporting Arms and Ammunition Manufacturers’ Institute specification, or at least a chamber that may not accept previously made loaded rounds due to headspace differences.  I had a rubber strap wrench hanging around and put it to good use to counter the twisting of the barrel.  One last torque and the rifle was re-assembled into the stock.

Overall the process was painless as well as exciting as long as you take it slow.  I took three shots below following zero and some break-in combined with some load work-ups.  Below is the 3 shot group of my current load.

Jason article Pic 4

The point of this article on swapping barrels on a Savage with a threaded barrel is that you don’t necessarily need a gunsmith to swap a barrel on Savage rifles. That makes Savage actions and rifles a versatile indeed!

Editor’s Note: This tight 0.28 inch 3 shot group that Jason shot is the result of experimentation with many variables such as the new barrel,  bullet, powder, cartridge case prep, primer, overall length and many other details. In addition we compute standard deviation and extreme spread to maximize long range potential.

Savage Model 12 LRP 6.5 Creedmoor System Test Products Arriving updated 5/24

My heart quickens at the thought of testing each new rifle, scope and accessories here at New Hampshire Rifleman… Like Christmas in the summer.  As you are aware if you read articles here at New Hampshire Rifleman, we are going to test the Savage Model 12 Long Range Precision Rifle in 6.5 Creedmoor. I am told that this Rifle can really shoot and sports a 26 inch barrel/w 1-8 twist. It just arrived to my FFL. I drove over just minutes ago and filled out the background check as usual and the rifle is home in my office  Wow! We shall see. I used my Lyman Electronic Trigger pull gauge and the Target model accuTrigger weighed in at an  average of 2 lbs pull out of the box. The red target trigger is adjustable  as low as 6 oz and as high as 2.5 pounds.

DSC_0005

I ran a Hornady bullet OAL gauge in the bore to find lands at 2.868 inches w/ my Sierra bullets.

Max SAAMI COL is 2.825 but need one caliber worth of grip to hold bullet which will be closer to 2.80 inches for a safer COL for this bullet.

 

 

 

along with a “New” 2016 Leupold VX-3i/w aggressively redesigned power selector. Shipping to NH Rifleman soon…

a 20 MOA Picatinny rail add-on to reach out there and the famous RX 1200i DNA Laser rangefinder with TBR.

And the test bed Match grade 142 grain bullets from Sierra – The Bulletsmiths®

6.5 mm/.264 Caliber (.264) 142 gr. HPBT MatchKing (100 bullets)

and

Cartridges with the new Hornady® ELD-X™ Hunting bullets see earlier article. The Sierra bullets and cartridges have arrived but no rifle yet but it is on its way to my FFL dealer here in Plaistow, NH.

I will hand load the Sierra’s, one at a time… details to come.

AR-15 Barrel Break-in and Bore Cleaning

After having tested several hunting rifle barrels from new, my observation is that, in general,  rifles improve in accuracy to some degree if not broken in at the factory already. But all new rifle barrels should be cleaned before you put bullets through them whether broken in or not.  I find residue in all cases for new barrels.

On new rifles and barrels I use a solvent laden bronze bore brush and then 1 soaked patch of your favorite bore cleaner that also addresses copper fouling and then around two or three dry patches. Web research on chrome lined barrels is that you should clean it like an unlined barrel just less frequently some say after 200 rounds. I bore snake my AR barrel after each outing as a practice but did not use any specific method to break it in, believing that I did not need a regimented plan. After a session of 20 or 30 rounds I have touched my chrome lined barrel for heat and find it just warm to the touch and never hot. My AR is new and has only 150 rounds through it. Some say the barrel is not broken in yet. I would strongly avoid any abrasives in a chrome lined barrel as it will surely wear the chrome away. And be very reserved in its use for break-in on steel barrels.  I scrubbed the barrel only once with a brush since new and wont scrub for another 100 or so rounds unless groups deteriorate.

On hunting rifles I have use JB Bore Bright, (an abrasive) very sparingly if groups seem out of  normal but in general it does not get used much at all.

I once tested a 300 Ruger RCM that shot 1 3/4 groups at 100 yards but later tightened after use and normal cleaning to sub-MOA. The truth is just the shooting alone may have cleaned the bore or as some say, shooting seasoned the barrel.

I think it is a best practice to at least run a bore cleaner soaked swab through a bore if your not sure of fouling. How the swap comes out is the tell all.

I avoid using soft copper bullets in my hunting rifles as cleaning can be a pain to get soft copper out of the lands and grooves. Some folks swear by them, I swear at them.

I prefer the harder gilding copper which is used on regular hunting bullets and on some brands of solid gilding copper bullets such as the Nosler eTip® that I just used on a whitetail buck this past fall. Don’t over do barrel cleaning and remember to take some fouling shots before shooting for group. At least one and perhaps 2 or 3 is better.

A hunting story of barrel cleaning and lack of it comes to light as a hunting friend of my father shot a Savage 300 in the deer woods. He shot that rifle one or two shots before the deer season then hunted with it. Never cleaned the barrel after many years and when others complained that he never cleaned his rifle the would put a hole in a coke can at 50 yards to shut them up. I am not sayin’ never but his rifle never had “solvent stink” and oil smell in the deer woods and he killed lots of deer.

On the target range is another story, there you don’t care about smell you want clean!

Long Range AR-15 – Putting It All Together by Ed Hale

I must admit that there was “much” needed for this AR-15 to be ready for real long distance and it may be that “more” is needed to accurize it. So what did I do to make it more suitable for long distance? Use a systematic approach that  makes sense without going overboard.  And use what you have as much as possible; improvise,adapt and overcome says the “gunny”. I keep saying that, for sure some of that will happen.

cropped-IMG_0909.jpgFirst was to change the mil-spec trigger. As you can see from a previous article I installed a 2 stage Timney Trigger.

Screenshot (6) copy

It has 2 pounds pull in the first stage as it is squeezed rearward and then 2 more pounds to break and release the internal hammer within the trigger. It is crisp once the first stage is complete. Next was to put a better scope on it. Leupold’s VX-6 is an outstanding scope  with a working range from 3x to 18x with a 44mm Objective lens.

a zero to 600 ad

The VX-6 is unique in all rifle scopes for its 6:1 Zoom capability, with unserpassed light transmission and optical clarity throughout the entire magnification range. This was the scope that helped me drop my whitetail deer at 300 yards this past fall. See this link.http://www.nhrifleman.com/2015/11/02/savage-11111leupold-vx-6-and-nosler-e-tips-field-test-by-ed-hale/

The scope model includes the Illuminated Boone and Crockett Reticle with the option of creating a Custom Dial System (CDS) for dialing in your favorite bullet, (based on the ballistic coefficient) out to 600 yards. I have not  entertained creating the CDS dial as I keep moving it onto different rifles and calibers. It is such a rock solid scope that I use it to test rifles. Next, I mounted a Mark 2 Integral Mounting System. (See the article on it)

Ammunition: I am using Nosler Custom Competition ammo as you may have already seen in early articles. I will be testing 69, 77, and 80 grain bullets at longer ranges with different powders and cartridge overall lengths.

DSC_0001

 

I am in training too.

Reloading: I found that Custom hollow point target bullets need special attention when seating them so I did some research and purchased a Redding Custom Competition seating die below. The design of this die and its capability of keeping the cartridge straight and in alignment with the bullet is not only well known but perhaps even legendary.

DSC_0002

Powder: You will need to experiment. Right now I am using Reloader 15 powder.

Reloder 15

Behind the Rifle: I have visited Sniper Hide and found a piece on Breathing and Natural Point of Aim. There is a video there you can purchase. I chose to read and practice. They instruct to break the shot at your natural respiratory pause (meaning at the bottom of your exhale). https://snipershide.mycustomevent.com/ShoppingCart.aspx?com=detailview&iid=103&cid=247

I never trained to shoot at the bottom of my exhale but somewhere in between. I have lots to unlearn it seems but some I did well on too. I need to play with cheek weld on my AR stock too, which will cause your shots to never fly well if you can’t weld your cheek consistently.  I am very unfamiliar with the collapsible stock settings too making it a real learning experience.

 

I found a number of sites you can google on shooting techniques for long range. They are too numerous to list but the word to the wise is practice each day if you want to win matches. Dry fire with snap caps can help but remember only perfect practice makes perfect. I must put lots of bullets down range too using the skills I have learned. You can do it too. I am looking forward to loading up some rounds and burning some powder.

Good Shooting!

Leupold Scope – Integral Mounting System for Picatinny Rails by Ed Hale

Pictured on the front page of New Hampshire Rifleman is a new image of my AR-15 with Leupold’s one-piece cantilever integral mounting system for scoped  rifles such as my carbine with Picatinny rails. The model I am testing is the Mark 2 IMS for 30mm Scope bodies. It does the job and fast mounting! Great for tactical scenarios or just rapidly swapping over to other scopes or other aiming devices. 

https://www.leupold.com/hunting-shooting/mounting-systems/integral-mounting-systems/mark-2-ims-30mm-integral-mounting-system/

What makes this model so attractive is its easy attachment of the IMS system to the Picatinny rail. Just a few minutes and it is on and snug.

This is a great solution for an AR needing a long range scope such as my VX-6 . As you can see it is a beefy mount that can take punishment of an AR.

If I were shooting a magnum rifle I would likely use additional top ring screws to keep the scope in place during heavy recoil. See the upgraded Mark 4 IMS system below for 30mm.

Applying proper torque is critical and Leupold recommends the following maximums:

6-48 Base Screws – 22 in/lbs

8-40 Base Screws – 28 in/lbs

8-40 Ring Screws – 28 in/lbs

Ringmount Keeper Screws 45 in/lbs

The ring screws on mine are 8-40 and I did snug them with 28 in/lbs with my Wheeler fat torque wrench below.

.wheeler fat wrench

Back to the IMS mounting systems. If you want more IMS security for your scope the Mark 4 System base can be purchased. https://www.leupold.com/hunting-shooting/mounting-systems/integral-mounting-systems/mark-4-ims-integral-base/

and then you can purchase the Mark 4 IMS insert below.

https://www.leupold.com/hunting-shooting/mounting-systems/integral-mounting-systems/mark-4-ims-30mm-integral-ring-insert/

It has been the practice of many shooters to place an indelible pen mark where the ring and scope mate. Over time you can verify with the mark that the scope did or did not move. I would do that here as part of my test which will last several weeks. Look for more feedback on the Mark 2 IMS system.

There are lots of scope mounting systems on the market but as I have said before, I trust Leupold products to deliver. You just have to choose the right product for your application.

Good Shooting!
