I'm loading with Power Pistol, used 115gr LRN from Space Coast Bullets, 5.2 grains with the OAL at 1.095", (I would've loaded longer but that's one of my guns, a PF9, needs). So far no problems, I recently ordered a chronograph so at some point I'll find out how fast they are. I AM new at reloading, don't see any real problems with leading, all the rounds went 'bang' and the guns still work.
