Here's what I've found. New NC spring, dry gas system, wet bolt, high brass 1300 fps shells. Tried AA 1300fps shells, and would not run more than 3 or 4 at a time and would double feed. I was very discouraged. Brought out the cheap Nobel high brass 1300 fps stuff I bought at the clays club and the damn thing was a sewing machine. I'm about half afraid to try buck or slugs.

I think the stock spring was too light, and let the follower bind it up past the extension tube. There is a rough spot at the connection, but right now above my skill set to smooth out. Can't explain the high brass, except maybe the shell stop just likes it better.

Hope this helps someone out.

I've had great LUCK with the Federal Target Load 1 1/8oz 7.5 shot. Had <2k rnds thru my SpX and around 1k thru my PRO. A guy borrowed my Pro last wkmd for a stage and shot some 1oz 7.5 and no issues
