Re: Need Your 7 SAUM Load Data
I found 64.5 gr of H1000 with the Berger 180 Hybrid shot excellent at 300 yds. But when I tested the same load at 640 yds I was getting high signs of pressure. The shots at 300 showed a slight ejector mark, at 640 the bolt was stickier than I'm comfortable with. Not sure why, maybe it's just the brass. The COAL for this load in my rifle was 3.085" which is .010 off the lands.
Also, 65.5 gr of H1000 with the Hornady 162 A-max shot excellent at distances up to 800 yds. According to Exbal, they were going 3057 fps. However, when I loaded up another batch of this load the accuracy wasn't nearly as good (from .3 MOA to .75 MOA). The COAL for this load in my rifle was 3.017" which is .005 into the lands.
I'm gonna get some new brass and try these loads again.
