OAL for 115gr MG JHP

Remember that the Max OAL for 9 mm is 1.169. The shorter the OAL, the higher the pressure. I load both 124gr Berry's RN and 124 gr Montana Gold CMJ to 1.150 in my Gen3 G34. I advise you to experiment with different OAL's to determine what's best for you and your gun.

I loaded some to 1.175" and they were dragging on the front of my STI mags. SV mags, 38 Super with no spacers, work fine, but STI's are iffy. I dropped the charge and shortened them to 1.155" and the issues went away.

My CZ likes an OAL of 1.145.

As was said before, you will need to size your rounds based upon the particular platform.

A tight match barreled 1911 usually shoots it best at 1.080 OAL. I have found that loading them to 1.120 is a good compromise length that runs in pretty much any platform and is short enough to get a good burn with medium powders, which gives great accuracy.
