  1. Does anyone think 9mm MG 115gr FMJ over 5.0 HP38 seated to 1.125" would be pushing it to exceeding recommended max pressure? I chronoed this same load at 1.150" and it measured about 1130fps out of a 5" barrel. With the .025" shorter COAL, will it push the pressure/velocity pretty significantly? I know the books and the powder label call for 5.1gr max for 115gr for 1.125", but that's for HP. Not sure how long GDHPs are, but mine are .562" long.
