I bought a $500 Armscore 9mm 1911 last week and loaded 6 grains of PP with a 125 hard cast bullet sized to .356. It was getting late but I benched it with 9 rounds at 25 yards. The group was about 3 inches with 7 about 1 1/2 inch. No muzzle flash out of the ordinary and it shot point of aim. I am not a 9mm fan but it may grow on me. I already had the brass and mold and lead so $5 per 100 will be fun as soon I smooth the trigger a little. The OP is asking about PP.
