I purchased my PC carbine about 6 or 8 months ago for USPSA competition, PCC division. Started out great! Loved it. Then about 1000 - 1500 rounds later I started developing stove pipes, which became more and more frequent. I considered my ammo first. I was running 4.2 grains of WSF behind 124 grain FMJ bullets and thought maybe that was too light a load (all of a sudden). I increased the charge to 4.5 grains and the problem seemed to get worst. So I tried some commercially manufactured ammo (CCI Blazer). The problem was even worst. Leading me to think the bolt is cycling too fast rather then too slow. I generally clean everything after every 200 - 300 rounds so I can't blame it on a dirty gun. I've heard where the ejector can get bent, but mine looks fine (at least as I can tell). Any thoughts?
