I used 47.5 Benchmark. That also was 2810 with the Cutting Edge bullets. I only had 5 of those left so limited testing. BC is better with CE so probably a better place to start (est. .398 vs. .368). How high of an elevation will you hunt? The Hammer load will get you there at 10-11k which is where I elk hunt. 46.5 H322 is 2800 with the Hammers, though I have not tried for accuracy yet. Plan to try AA2230 next. That powder will definitely produce higher velocities, just a matter of whether it turns out accurate.
