[QUOTE="JTH, post: 2452107, member: 59647"] Here’s some data from the Hammer Hunter reloading thread: [I]7 Sherman Short (WiscGunner) 155 HH 26" Proof, suppressed, tw ???? ADG F210 2.960 OAL H 4350 54.0 54.5 55.0 55.5 56.0 56.5 57.0 57.5 58.0 58.5 2942 2938 2970 2980 3014 3045 3067 3095 3113 3132 One ragged hole Stiff bolt, ejector Very stiff bolt, ejt.[/I] Formatting didn’t come through correctly on the info above but hopefully you can follow it. Obviously use good judgement and start low. The one ragged hole was the load at 57.5 and 3,067 fps. Pressure signs started showing up at 58.0 I’d be looking at a little slower powder, maybe H4831sc or RL23, to get closer to a full case and pick up a little speed.
