I've been experimenting with AA 5. The goal is to be between 1100 and 1200 fps with mild recoil. I can obatin just over 1100 fps with 14 grs under 240gr xtp, but my hand takes a pounding. I've been buying 240 SWC made by Enforcer Inc. They come out at nearly 1200 fps (I realize not apples to apples with the swc and xtp) and are pretty pleasant to shoot. Anybody know what powder Enforcer uses or have any suggestions?
