Cain, what weight bullet? I've used IMR 4895 and 150 gr bullets with okay results.
Here's a combo I know works: IMR4064 and a 168 gr HPBT. Saturday, my slow fire prone at 200 (600 yd simulated) was 195-5X. And that was while a diagonal shadow (from the top board on the target frame) was moving across the target and I was cranking in left windage every few shots trying to hold the ten ring. I'm not a big ball powder fan. sundog
