Most USPSA (IPSC) shooters reload. There is a minimum power factor floor
of 165 (bullet weight in grains X velocity in FPS divided by 1000) to make
major power factor.
For a 230 gr bullet that translates to a minimum velocity of 717.4 fps.
Adding in a little cushion, I reload 45 ACP to 750 fps for a 230. That is
a bit lighter than the military ball load.
On the other end of the scale, I reload 9mm to major power factor for my
open guns--pushing a 124 gr bullet to 1350 fps. W-A-Y over ANY factory
load in 9x19.
