I've decided to move from rifle reloading to now doing some pistol. I tried my hand at loading a some 9mm rounds using Shell Shock NAS3 cases, Federal 200M primers, Alliant Power Pistol powder, and Zero 147 HP bullets at 1.145" OAL. I loaded up 50 rounds at 4.0gr Power Pistol and just got back from shooting them. Observations....
In my Grand Power Xcalibur, the rounds fed and fired flawlessly. The recoil was extremely smooth / buttery - I could shoot this all day. Very accurate. Slide locked back consistently but just barely. There were two cases where I ejected a mag and the slide closed. I've never seen this before. I'm using the "standard" strength recoil spring.
In my HK P7M8 the rounds fed and fired flawlessly. Accuracy was the best I've ever seen. The slide consistently did not lock open on the last shot. The recoil impulse felt on par or stronger than the normal 115gr range ammo.
I'm thinking that 4.0gr is a tad weak and I'm going to go up to 4.2gr to increase reliability. I think I'm still within safety margins both because I don't see any pressure signs and because the NAS3 cases can deal with higher pressures. I'm paper punching / fun shooting and want an accurate and reliable round with reduced recoil. I'd love some advice from more experienced pistol shooters on tuning this load.
