165gr Sierra JHP @ 1.260" 9.8gr Power Pistol w/ CCI LP Stock G20sf Average: 1,311 fps/ 630 ft-lbs Brass looked great (was using 1x Remington Nickle) and feel the book max of 10grs is perfectly safe. I'm really liking Power Pistol more and more. 10gr is shown to get 1314 fps and I'm right there with 9.8gr. So far with 10mm, Power Pistol has been very, very close to giving me what they said it will, and I like that. I tested some Longshot with the same setup as above today also and while it's velocity averaged higher, PP was a little more consistent. I'm sure it could be driven faster, but in the stock setup, I think 1300+ is plenty fast for a 165gr.
