Don't think it was the 930's fault, but just ordered 500 rounds of better stuff from graf. It feeds low powered target loads with no hiccups.
I did do some tweaking, some needed some ue to ocd. Initially pellets and slugs were hitting really high, so replaced front bead with taller one, problem solved. Shell lifter was chewing my left thumb so i tore it all apart and cratexed the sharp points, plus opened the loading port, which was already beveled, and no more thumb bite and it feeds more smoothly. The trigger was somewhat creepy and pull was about 4.5 lbs. Some mild stoning and polishing and its a smooth, short 3.5 lbs, no overtravel thanks to factory installed overtravel screw in trigger guard.
I have only recently started 3 gun, shot 3 to date, and did not want to invest the typical $1100 for a big name sg, so the 930 made sense. From what i've read on brian enos' forum, all the factory guns need some tweaking; ports opened, lifters welded, extended mags, etc. For the money the 930 is a good deal, and can get the job done.
