Have an MP mold I received from a gentleman on here that casts both HP and FP’s. HP is at 180’ish and HP at 195’ish. I know around 200 gr. Is pushing case volume for the .40 but was wondering if anyone had some powder suggestions. Also, after purchasing many once fired cases a while back I discovered some that were a few thousands short of the .845 trim to length (like .840+”).
EDIT: my bad, I found a 200 gr “RCBS#10mm-SWC” section in Lyman 4th Cast Bullet Handbook. Still listed under 40 S&W. Any other ideas are welcome.
