Range disappointment after shooting reloads
Posted: Fri Apr 17, 2015 7:12 am
Figure this goes in this section. Went to the range yesterday to test out 6 different powders reloads. 308 AR with 16 inch barrel. Everything was going fine until 2/3rds the way through. All of a sudden my shots were going all over the place. WTF. I stop, check to insure the scope didn't come lose. Nope. I always bring factory A-Max rounds as I want to mimic this round. This round is always shoots great. So after about 50 rounds of my reloads, and verifying my scope didn't come lose, I broke out the commercial stuff to see WTF was going on. Shoot, make adjustment on scope, shoot again to see the round went another direction. I burned through 3 boxes of commercial hornady ammo fishing to re zero. I gave up. Range master said barrel heat up. Barrel was a little hot but didn't seem real hot. Always stopped after 5 rounds to inspect the brass and write down my notes. So, to you pro's, will a heated up barrel cause this to the point of not able to zero? Was shooting 100 yards.
