First I'd like to thank everyone for their input. I took all suggestions and did some experimenting. The first problem I had was with the 12rd Surefire magazines. I have 3 and all of them had a lip on them where the top of the magazine joins the main body of the magazine behind the brass. This was causing brass to catch. As pointed out in the last post you can check this easily by manually cycling a few rounds. Also as previously mentioned, they can be fixed by sanding down the back edge of the magazine until you can run you finger nail over it and not feel the edge. Then retest by manua

I'll lower the setting on GUN FIXER GAS PLUG to -1 and try smoothing out the mag. Also, I read at http://earthseaphoto.com/SagaofMySaiga.htm that it's better not to fill the magazines past 90% and to break in the gun with Wolf brand slugs. Any thoughts?

The mags that came with it were 12 round mags so there was no OEM Russian mag with the shotgun on delivery. I've tried to find them but locating OEM mags is just about impossible.

It either misses the round all together or catches the round just before it gets chambered.
