Heavy 9mm success! 158 grain SWC.

[lotech]

As for overall length, I seat all 9mm bullets to maximum OAL as long as they chamber. I've tried many and found very few that could not be seated to max. These include the SAECO 120 grain FN, RCBS 147 grain FN, and the Lyman #356637 157 grain FN, and a couple of .38 Special SWCs. I wouldn't use a 9mm bullet that couldn't be seated to max. magazine length. Powder capacity is just too limited.

wonder what the velocity is with your heavy 9mm rounds

With the starting load of Bullseye from the Lyman #45 manual the 16" RRA run 890 fps and the 4" PPQ ran at 788 fps for the 158 gr RN and the 147 gr FP was close to this velocity also.
These were loaded to 1.165" OAL and will not chamber in some other 9 mm's.
