I would expect HP-38 to be promising, it's got a long standing good reputation in the ACP cartridge but Titegroups "claim to fame" is small charges in large cases (fast burning and not position sensitive) would probably be a good match too.
Never used Autocomp, Green Dot or SR7625
I'm supposed to hit the range with my BIL and my new .45 Colt Smoke Wagon and 255 rnfp handloads using 231 (HP-38), Unique, Universal, Accurate #5, Sport Pistol and Titegroup: all "cowboy" type loads, nothing "hot".
IF I get to go (I have my doubts, my BIL isn't the most reliable guy I know) I'll report back with any relevant observations.
