Re: berger vs Amax
You're getting some excellent accuracy at 600 & 1000 yards!
You could shove the 180's a little faster and see what happens... Last few years I've been sending the little 115 gr Berger Hunting VLD's downrange at about 3200 fps from my .25-06, and have taken three mule deer along with coyotes with that combo. No bullet problems. All deer dropped instantly, at 175, 230 & 400 yards. Coyotes really get ripped up on bullet exit, no doubt. Accuracy is good, but not like you're getting - then again I'm running a factory built Rem 700 CDL with a 6x scope, not a target/varmint type rifle.
