Have gotten 1" groups at 100 yds with this load: 165 gr Sierra Pro-Hunter and 57 gr of IMR-4350. Then I tried 180 gr BT bulles with the same powder in charges of 55.5, 56, 56.5, and 57.0. Accuracy was much worse. The brass showed signs of over pressure at 56.5 and 57 grains.
Curious: Is it likely I could get better results with 180gr BTs if I switched to H4895? I have some H4895 and will likley try it just to see once I verify a charge weight range. Just curiuos if I should EXPECT accuracy to be better with this powder.
