I was interested in this after talking with a few shooters that load many thousands of rounds per year. Some have done it, most suggested starting at the lowest charge and reduce that by .2 gns. The only drawback I've heard about is maybe a light primer strike in some pistols.
I figured the best place to start was with the Ruger PC9 since it's after all, a rifle.
Here's what happened today.
Brazos 147gn Hi-Tek RN
3.0 gns W-231
1.125
902fps avg.
Winchester SPP
Brazos 147gn Hi-Tek RN
2.8 gns W-231
1.125
867fps avg.
CCI SRP
Looks like I could have loaded the same charge without much difference. I may try some lighter bullets in my pistols and see it I have any issues. Good to know I can extend my 9mm shooting with them if need be.
I meant to post this in ammo and reloading, move if need be.
