Been loading 124FMJ with 6.2g of Power pistol. Seem pretty stout, not seeing any pressure signs, haven't chrono them. Accurate. 1.125 OAL. The cases are pretty full, close to being compressed. Was thinking seems to be a pretty heavy charge considering I use 6.7g behind a 180g FMJ in .40. They got some bite out of the M&P. Have to take into account the pyrotechnic display of P.P. I need to take the chrono to the range.
