Reloading and Shooting Thoughts for Long Range Hunting.

It is important to recognize that there are significant differences from hunting vs target reloading/shooting.

Hunters want a light rifle, (6 to 9 pounds) that shoots accurately out of a cold barrel.

It is the first cold barrel shot that really counts to anchor your big game, not the second, third or fourth shot.

Sure, a follow up shot is also important in the case that your game is still on its feet, but that first cold barrel shot is key.

Shoot for 3 shot groups not 5 shot groups.

7/8 inch

Target shooters on the other hand want a heavy rifle and  heavy barreled rifle (often well over 10 to 20 pounds to absorb heat from the barrel and reduce felt recoil. Best target groups are from a warmer barrel not a cold barrel. And the bullet is chambered to engage the rifling thus increasing chamber pressure.  

Hunter’s who reload, prefer to reload to around 15 to 30 thousandths off the rifling lands and often can shoot a hotter and faster bullet to maintain more delivered energy to big game. My 7mm Rem Mag Browning X-Bolt delivers 2000 ft-lbs. of energy at 550 yards. 

By reloading for your hunting rifle, you can customize case, powder, bullet and primer, save cost, get more satisfaction,  while increasing long range accuracy from a cold barrel.

Since preparing to hunt moose this fall, at long range, I pay more attention to case concentricity, seating depth and neck tension. It has helped greatly.

One final thought, I swab the bore at the end of cleaning with a degreaser solvent to remove any lubricant or cleaning agent to improve the first cold shot.

It works great!

Good Hunting!

In prep for my 7mm Rem Mag cartridge custom loads and my fall Newfoundland Moose hunt I had some difficulty getting Reloader 22 powder for reloading my 7mm Rem Mag.

Accordingly, I purchased some available Vihta. N560 Powder that Nosler had listed for 7mm Rem Mag with Nosler 175 grain ABLR’s with a 24 inch barrel and 9 twist.

Its burn rate is near to RL 22. My rifle is a 26 inch barrel and 9.5 twist. Subtle differences in length and twist can shift ideal powder burn rate preferences to one side or another. You just have to find the sweet spot and the powder. 

Early N560 Powder results showed extreme spread (ES) and standard deviation (SD), at lower velocities, were excellent, thus I continued working up the load. 

Many handloaders have found that some rifles with 9.5 twist rates do not like the 175 grain bullets’ accuracy but so far my rifle likes them with this N560 powder.

As those who experiment with loads are aware, powder, can and does vary from lot-to-lot, thus backing off to starting loads and working up slowly is best. Observing the cartridge case and resulting primer can tell quite a bit as you approach a max load. As you incrementally approach hotter loads, the primer will begin to flatten into a pancake.

I try to avoid what some call “sticky bolt”, a term for supposedly “manageable” over pressure. So far so good.

As I load each round, I use a sharpie pen to write the powder name, grains, and bullet type/weight used on the brass.

I have achieved the near to 3000 fps under preliminary testing at an outside temperature of 45ºF and cartridge and primers look flatter but normal. First 3 shot group was just 1.0 inches at 100 yards. 

Next is to check for Extreme Spread and Standard Deviation below with Labradar data.

JBM Ballistic Data indicates 1891 ft-lbs delivered at 600 Yards, 10 mph crosswind moves the bullet 17 inches left or right. At 500 yds delivers 2100 ft-lbs and 11 inch crosswind. At 400 yds delivers 2330 ft-lbs and 7 inch crosswind.

Next is to practice at those distances and collect real field data to see what limitations surface. More to come!

Good Hunting!
