Bullet Stability/Barrel Twist – Browning X-Bolt 7mm Remington Magnum – UPDATED

Posted on by

I purchased a Browning X-Bolt for Christmas. Hurray! But bullets are a bit harder to find. I did find a 175grain Nosler ABLR bullet that I liked and purchased it but later calculated the bullets stability to be 1.37, just below the 1.5 military stability criteria in my 1 in 9.5 twist rate barrel. Bullet length included the polymer tip in overall length. Without the polymer tip as part of the bullet length, the formula now says the bullet is very stable. 

Experts argue about including polymer tips or not.  I will load some in a week or so.  

Lets take a look at this imperfect science…

It is known that barrel twist rate and a given bullets size, length, BC and velocity effects bullet stability. As a general rule bullets that are exiting the barrel have some yaw or as some say “yaw spiral” or gyroscopic effect.

It is the bullets “yaw” that can affect the grouping of a bullet, but yaw diminishes as it travels down range making groups tighter..

Calculators

You will need the length of the bullet below to enter this in the stability formula. Some folks subtract the polymer tip from bullet length. The JBM formula below takes the polymer tip into account. Measure the bullets overall length and measure the polymer tip length.

At typical 100 yard ranges your bullet may exhibit some yaw thus grouping may be somewhat larger than expected. I ran into this with the .243 Winchester and my former 338 Win Mag where yaw was pronounced with heavy, longer bullets. 

The good news is, this minor yaw will disappear at longer distances and stability and grouping improves, 

The only way to know how stable your bullet is, is to shoot some at temperatures and distances your going to hunt in.

Accordingly, I would fire them at 100 and 150 yards and then shoot out to my max hunting distance of say 500 to 600 yards for group. 

UPDATE

I had some Nosler 140g E-Tips and 7mm brass in my cupboard and eagerly loaded and shot them at 100 yards with 62g IMR 4831 powder clocking an estimated 2900 ± fps at the muzzle. Yes, that is a bit slow, but Nosler recommends working up loads with gilding copper E-Tips.

Below is the very first 100 yard 3 shot bench rest group. It measured 3/4 inch. Sub-MOA! Luckily there was no measurable wind and I used a COL of 3.24 inches where my bullets had at least 0.05 inches off the lands.

 

Can’t wait for my heavier bullets to arrive. 

Good Shooting!

 

Browning X-Bolt Speed Rifle under the Christmas Tree

X-Bolt Speed

Browning X-Bolt Speed in 7mm Rem Mag

My readers are aware that I am hunting moose in Newfoundland again. My last moose fell to a single shot from my .375 Ruger, but because of recoil, I took precious seconds to chamber a second round. By the time I had a round in the chamber, the moose fell.

I did not practice this chambering of a second round. I suppose if I were hunting Cape Buffalo, my practice would have been quite different …as if my life depended on it. 

As many have said, “Moose often do not fall quickly to a single shot.” And they can move quickly into cover making a second shot more difficult.

The shooter must be prepared to quickly, eject the spent case, rechambering a new round and  follow-up with a second or even third shot. There is plenty of video evidence of this follow-up on the internet. 

With larger traditional heavy recoiling rifle calibers like.  a 300 Win Mag or heavier, the shooter takes more time due to recoil. He lifts the Mauser like bolt high at 90 degrees, pulls back hard to empty the chamber and closes the bolt with a second round. 

The Browning X-Bolt “Speed” in 7mm Remington Magnum above has one of the fastest bolt throws on the market today. The “speed” refers to the short bolt throw 60 degrees to eject and smoothly chamber a second round.

Bolt throw Speed was key to my purchase and I tested many bolts first hand as I shopped. 

I purchased this rifle with a 26 inch fluted barrel in 7mm Remington Magnum with a removable muzzle brake. I installed my Leupold VX-6 3-18 just like in the image above. Love that scope!!

Since I reload, I found some new reloading dies for it.

Trigger pull is adjustable down to 3 pound but came set to 4 pounds.  The caliber choice 7mm Remington Magnum works for both short or long range shots out to 500 yards with Nosler’s 175g ABLR.  On  paper, ballistic data says the ABLR leaves the muzzle at around 3000 fps with max load RL 22 powder. We will see what I get for accuracy as some rifle barrel twist rates have stability issues for the bullet.

 My ballistics chart says, at 500 yds at sea level and 40ºF the 175g ABLR will clock 2332 fps and have  2113 ft-lbs of delivered energy.

More soon!!

Die-Hard Moose – Practice for an Immediate Follow-up Shot

Posted on by

My last moose taken in 2019 was killed with a single shot from my .375 Ruger, but I held off as he stood bewildered and collapsed after a few seconds.

My rifle recoil was significant as I sent a 300 grain Nosler AccuBond at him.  At the greater recoil, it took me longer to eject the spent shell and put a new one in the chamber.

I was too slow to cycle the bolt because I did not practice it in advance.

I am moose hunting again in Newfoundland this coming year, and If I can’t cycle the .375 to my liking, I’m debating to shoot a rifle that allows a faster bolt cycle but still has plenty of down range energy. I’m thinking 7mm Rem Mag or 30 cal like the 30-06 Springfield. 

In researching moose kills, most require MORE than one shot to anchor them. Their nervous system appears slow to react to a kill shot.

Accordingly, practice should include cycling the bolt in earnest and get a second shot into your moose to anchor it. Yes, your first shot is still critical but cycle the bolt and be ready for a second shot.

Further, listening to other big game hunters, to try to use less scope magnification for a wider field of view and follow your bullet contrail hit.

 

Newfoundland offers enough open landscape for shots out to 500 yards or more. Shooting a rifle that has poor energy e.g., 1000 ft lbs at these distances limits the hunters ability to reach out. Spitzers with sectional densities above .250 to .300 for good penetration and G1 ballistic coefficients (BC) of at least .4 or more to hold its downrange energy is ideal.

My personal moose killing energy minimum is 1800 ft-lbs and around 2000 fps for a good bullet mushroom. Accuracy should be sufficient to hit a pie plate size kill zone from your rest. Make it a goal to learn to use a ballistic calculator. I use

https://www.jbmballistics.com/cgi-bin/jbmtraj-5.1.cgi

Your bullet must arrive with enough killing energy and ability for your bullet to mushroom at those distances. It is sometimes the case that you have penetrating energy but the bullet does not adequately mushroom. Check that your bullet speed at the game should be near 2000 fps at the hit for mushrooming (lead core) and energy in the 1800 to 2000 ft-lbs. or greater.

Bullet manufacturers often publish the range of speeds that produce adequate mushrooming for your bullet choice.

Practicing for the first shot and follow-up shot to quickly cycle the bolt will give confidence to the hunter. I use a Bog Death Grip tripod for distant field shots.

Good Hunting!

Age of Hornady’s Precision Rifle Cartridges 6.5, 7mm, 300 PRC Target and Hunting?

Posted on by

The truth is that the 6.5 PRC is faster than the 6.5 Creedmoor, the 7mm PRC is faster than the 7mm Remington Magnum and the 300 PRC is faster than the 300 Win Mag.

Having said that: Should hunters run out and sell the Creedmoor, 7mm Rem Magnum or the 300 Win. Mag?

I think not, if you own them already. I love my 6.5 CM but am open to the 7mm PRC.

Well, The Creedmoor, 7mm Rem and 300 Win have great accuracy and punch for hunting already.

These PRC cartridges were designed for long range target accuracy and are somewhat faster, kick a bit more, than the aforesaid cartridges but not enough to replace them as a hunting cartridge. Others think similarly. 

As for target shooters, ceteris paribus, (all else being equal) it takes a faster bullet to win a match against the wind at long range, where fractions of an inch make the difference in point score. The PRC’s were designed “first” for target, having no belt, extremely concentric and in some cases can shoot a heavier bullet with a rifle with a faster twist.  

But, for example,  if you don’t own a PRC rifle or load for the cartridge, getting a new rifle in a PRC may be a good choice as a hunter hand-loader.

Note, the PRC cartridges and rifles are not in every gun store at this time.  

I love my 6.5 CM for deer and thin skin game hunting but do not as of this writing have a 7mm rifle, so I am keeping that in mind.

There are only a few rifles in manufacture at this time for the 7mm PRC but more are coming. Still cant go wrong with a custom 7mm Rem Mag or Weatherby Mag or even a 280 Rem.

In the final analysis, the rifle quality may make the difference in my choice, not just the cartridge. 

More on this coming.

Good Hunting!

Calling all Coyotes –

Posted on by

Below is a reprint of an article I wrote 5 years ago in pursuit of Coyotes.  I would carry a sidearm today for calling in coyotes. You may instead also be calling in bobcats (we are not allowed to hunt or trap bobcats in New Hampshire at this time, I am hopeful that the rule changes soon and we resume hunting and trapping them.)

This last fall my deer hunting friend, during muzzleloader season, blew on his grunt tube after he set up. In less than a minute a coyote came running at him looking for the deer. He fired hastily at it and missed it at 5 feet but parted some hair. 

New Hampshire Coyotes Soon Begin Looking For A Mate – Take Advantage

 

Calls for Coyotes

North Eastern coyotes are larger than western coyotes due to the great lakes grey wolf mating with coyotes in winter. See my article below.

Coyotes are attacking children today, beware!

Outdoor Life Reports on New Jersey Anti-Hunting Bill?

Posted on by

New Jersey Bill Would Require Landowners to Notify Neighbors Before Hunting Their Own Land

New Jersey Bill Would Hinder Private Land Hunting | Outdoor Life

Quote from Outdoor Life “Legislators in New Jersey introduced a bill last month that would change the state’s regulations for hunting on private land. Assembly Bill 3732 calls for an expanded safety buffer that would prohibit hunters from nocking an arrow or carrying a loaded weapon within 450 feet of any occupied building in the state. A3732 would also require private landowners in the state to notify neighboring landowners before they could be allowed to hunt on their own land.”

Hunter Success Comes In Many Forms

Posted on by

Recently, I had a buck in my sights standing offhand. Darn it, I could not steady my crosshairs. I was not confident of a kill shot, and did not try the shot. 

He saw me, and moments later… he melted away.  

” We will meet again” I thought.  “He is not going any where so maybe another time we will meet again… and I’ll be ready.”

I set up a stand in the same area the very next day. A double rainbow appeared where that buck stood just a day earlier. 

Success comes in many forms. Letting that buck go was a success in my ethics and… I was rewarded with this glorious double rainbow. Yes, can you see the second rainbow?

The rainbow had significance that this hunter can understand.

I enjoyed that view till the rainbow disappeared. 

Perhaps a rainbow will grace your stand too. Yes, I’d perhaps rather seeing the buck again, but I did enjoy the rainbow.

Good Hunting!

Tree Stand Burnout – Deer Avoid It

Posted on by

The perfect deer hunting tree stand location can become burned out if you use it too much. Dependence on a single tree stand for day to day hunting, places increasing amounts of human scent in that area. Your Busted!!

Smart hunters know that wind is a key factor whether on the ground or up in your tree stand. If deer are expected from the west and wind is blowing your scent toward them. Your stand time will be wasted.

Experts say, deer can smell 500 to 1000 times more than a human.

Here is a great article I found on-line by Mike Hanback. Check it out!!

Muzzleloader Deer Season Opening In New Hampshire Saturday, October 29

Posted on by

Good Hunting! 

Deer Season Dates by Wildlife Management Unit | Hunting | New Hampshire Fish and Game Department (state.nh.us)

The biggest advantage of muzzleloader season in NH is that the deer are calm and have not altered their feeding and bedding habits.

As regular firearm season approaches deer find places to hunker down and are more warry. The other big advantage of muzzleloader season is that does are coming into estrous and bucks are moving more. Stay warm. Dress in layers. I carry a small day backpack.  Have my license, a pen, a sharp knife, drag rope, first aid kit, hand warmers, water and snacks and a phone or communications device.

I tell family specifically where I am hunting. Perhaps you should too!

If in camo, I wear an item of orange like a hat or camo orange vest. Deer don’t see orange, but people do. Deer see movement!

I enjoy cooking and eating my venison, and thus gut my deer asap after tagging, and open the cavity to cool it as soon as possible to preserve that meat quality. I do not hang my deer more than a day or so before cutting.   I like to vacuum seal my meat or burger. It will last for a few years in a freezer and over time will often lose more wild taste and even tenderize some cuts. I have begun pressure canning too and it tenderizes the toughest cuts.

See you out there!

 

Reduce Felt Recoil Over 50 Percent with High Tech Rifle Recoil Pads

Posted on by

Perhaps it is time we stop whining about recoil! Fix it!

Honestly,  the fastest and least expensive way to reduce felt recoil from big game rifles  is to install a slip-on or grind-to-fit recoil pad that was scientifically designed to reduce that instant whack to your shoulder.  Yes you can use a heavier rifle. Not me.   Or a thread on device to your barrel, sure to give you an ear-ache. I’ll pass.

I have used both Limbsaver™ and Pachmayr Decelerator™ pads for the past 20 years to my great relief. I owned a heavy recoiling  Ruger M77 in.338 Winchester Magnum and still own and use my M77 African in .375 Ruger. One was fitted with a Limbsaver SVL Pad and the other was fitted with a Pachmayr Decelerator. Both cut my felt recoil by approximately 50% or so. Below is a video from Limbsaver.

I shoot these big guns off-hand in my t-shirt because the recoil is more of a push than a whack, thus making it easy for the shooter to absorb the recoil almost painlessly.

Even more,  you can reduce felt recoil on your young son or daughters deer rifle too. A  6.5 Creedmoor/260 Rem shooting a 120 grain bullet at 3000 ft/ sec creating about 14 ft/lbs but with a state-of-the-art pad the felt recoil is nearer to 7 lbs of felt recoil, less than a .243 Winchester. Below is from the website; https://shooterscalculator.com/recoil-calculator.php

Time to fix that rifle recoil is now!

Good Shooting!
