I've been shooting my stainless Interarms Rossi .45 for a few years now using +p+ loads. I found the sweet spot at 23 grains of Lil Gun under eithe a 300 gr XTP or 315 gr WFN. With receiver sights, it will stay under an inch at 50 yds. That steel buttplate sure lets you know it's there! I'm guessing those loads are about 35K psi and I'm using cut down 454 brass.
