Hey everybody, first post, but a long time Mossberg user. I finally stepped up to a 930 semi-auto after shooting Mossberg pumps for many years, but out of the box I'm having issues with the gun. I got the gun home last week and cleaned off all the packing grease. I oiled it back up a bit and went out to shoot. Right away the gun was having trouble fully chambering rounds both 2.75 and 3" shells. Its like they were getting caught as they were just entering the chamber. They would get caught either when dropping the round in the chamber and hitting the bolt release, and, at other times, from a shell coming from the magazine tube. Needless to say, I'm pretty let down by the gun right now. I recleaned the gun and lubed the inside of the receiver/chamber with a generous amount of CLP. While running wet, there was not a single issue with chambering rounds until I wiped/dried off the CLP and the issue returned. One photo is of a snap cap that didn't chamber properly just like the various shells I was shooting. The second photo is of the chamber. I suspect a rough chamber, sharp chamber lip, or rough shell lifter, but I really have no idea. Any thoughts or questions are much appreciated. Should I send it back to Mossberg? Help!
