I have some cast boolits from the 90358 mold. They are .452 diameter and weigh 255 gr. (Mine seem to be closer to 249-250 with the wheel weights I used). I'd like to find a good load in the 750-800 fps range to shoot out of my Mod 625-6 Mountain Gun. I've had the cylinder relieved to accept moon clips. It really likes the Keith style 255 gr cast ahead of 7 grains of W231, but that is in the Colt. I'd like to find a similar load in the ACP. Anyone have any suggestions? I can't find a load in my manuals for a 255 gr cast ACP.
