I clean all my guns after I buy them. I've tried wwb, Speer GD 185 and 230 grain, federal, independence, ranger 230+p, umc, and blazer aluminum. Never had a problem cycling ammo. I read somewhere that it's an 18 pound spring, but I'm not sure? I don't reload so I can't give any input there.
I'd shoot about 200 rounds each range session of target ammo and then 4 mags of SD ammo. I figured that if it jammed, it would when it was dirty. It never did though!!
