I got to the range and fired the Lee seater rounds. I warmed up shooting both guns, with a bunch of rounds previously made, Starline brass, Winchester LPP and 230 grain precision delta RN. Powder charge was 5.5 grains of HP-38.
After a few magazine in each gun I was blasting the center ring out of two targets at 7 yards.
Setting a new target, I adjusted the distance and started firing.
Two different rounds were used here, both with the Berry's 185 grain HBRN, both set at 1.265-1.270. One batch had 6.3 grains of AA #2, one batch 5.5 grains Bullseye.
These rounds were no where near as accurate as the warm up ammo with HP-38 and 230 grain RN bullets. The Bullseye rounds were less accurate than the AA #2 rounds. Both showed elongated bullet holes in the target...leading me to think they were tumbling in flight somehow? I only fired a few of the rounds using the Redding seater, just to verify, and they seemed to also have variable accuracy and elongated holes as well.
Reading and searching, I think I may have made these rounds to hot? I dont mean unsafe hot, but reading was suggesting that lesser charges were somewhat more accurate with these particular bullets. I will post pics of the "elongated" bullet holes once camera batteries charge.
Anyone have an accurate powder charge for these Berrys 185 grain, HBRN bullets?
Looks like a little more loading will be required...
