Henry LR 308 - first reloadings
Posted: Fri Dec 28, 2018 6:35 pm
This is a cross post from 2 other posts of mine in other threads on the board that were copied, edited and placed here for easy access to reloaders.
I bought a 308 Long Ranger about 1 month ago for future hunting of deer & elk and mounted a 1-4x Leu’d scope on it. I did a 20 round barrel break-in with factory ammo (shoot 1, clean, repeat for 10 rounds, then shoot 2, clean, repeat for another 10 rds).
Here are some things I had to consider prior to reloading:
1. The chamber in my LR is tight. Its close to a match chamber, there is no “slop” in it at all. Brass cases fired in other rifles then resized on the usual RCBS or Redding dies would not chamber. I had to get and use a “Small Base” sizing die.
2. The chamber throat would not tolerate any case that was a hair+ longer than spec. All “used” cases had to be measured and any above spec were trimmed .005" less than spec. That said, new factory ammo worked well and if it was first shot in the your LR, it may or may not have the above problems.
Now to reload… I chose the .308 150 grain Nosler E-Tip for its high (for weight) BC, its speed out of a 20 inch barrel (high compared to a heavier cup & core bullet) and its penetration abilities (very high for weight). Then I modeled a load on QuickLoad & QuickTarget software:
Cartridge : .308 Win. (SAAMI)
Bullet : .308, 150, Nosler E-Tip 59378
Cartridge O.A.L. L6: 2.780 inch = 70.61 mm (Short because that is where it fit/chambered)
Barrel Length : 20.0 inch = 508.0 mm
Powder : Hodgdon BL-C2, 46 grains
Primer : CCI 200
My personal max range would be about 400 yards because the long-time rule-of-thumb is for a minimum of 500 foot-pounds of energy for deer and 1000 for elk at impact. Here are my “about” results (scope set at 0 for 200 yards):
0 yards distance – 2730 fps, time-of-flight 0 seconds, 2482 foot-pounds, 0 inches drop
400 yards – 2013 fps, tof 0.51 sec, 1350 fp, -23.8 inches
500 yards – 1853 fps, tof 0.66 sec, 1143 fp, -47.7 inches
YMMV
The best of 3 loadings (45g, 45.5g, 46g), was 46g and was a 5 round 1 inch group at 100 yards (1 MOA ). Hoping .75 MOA in the near future with more rounds down the barrel.
