Why does bad stuff always happen at a match? I picked up my new Mossberg 930 JM, shot a couple of rounds of trap, patterned it, shortened and modified the stock, shot slugs through it and thought I was set for the Ozark 3-Gun Championship. Guess not. The first (and every) time a stage required an empty chamber start, I couldn’t get the first round to pop out of the 9-round magazine tube and load into the chamber. With one or two rounds in the tube, everything worked fine. Put in 9-rounds and I had to rack the bolt handle four or more times before it would feed. Once the first round was out, everything ran fine. It was just that first one that was a problem. I overheard another shooter talking about the same problem. He said he’d taken the magazine tube off and polished the end of the carrier latch through the front of the gun to solve the problem. Looking into mine, going through the magazine tube opening seemed awfully tough. Luckily, Mr. 930, Jerry Miculek, was also shooting the match, and I asked him about it. He told me some of the guns have that problem, others don’t. Polishing the tip is the cure. He also gave me a pointer on how to get the carrier latch out of the gun. There’s a small slot, just below the latch (Photo 1, below). The pivot/retaining pin for the latch passes through that slot and is held in place by a little bitty version of what I’ve always called a “hitch pin”. Jerry suggested using a flat pronged automotive fuse, and putting a 90º bend in it to slip into the slot and slide the “hitch pin” out of the way.
