RL 26, IMR7977, H1000 and IMR7828 (either one) for the heavies may just surprise you with both velocity and accuracy. Running 7977 w/ the 110 AB in both of mine. Pushes them out at 3175 and 3200 respectively. The one has over 3000 rounds through it and still prints .75" consistently with either 3 or 5 shot groups. The other, 'slower', one prints them just over .5" to .6" groups.
