No, I shot pretty much only birdshot out of mine and have yet to experience a malfunction. The birdshot has ranged from the sale deals at Big 5 to whatever Wallyworld has. Even 100 rounds of the the dreaded Winchester Universal 8 worked fine.

We took it out to Burro Canyon and shot a bunch of stuff through it and had no problems.

Then we got the prototype stock made. Now we had to cut down the recoil spring tube to fit in the stock. We took it out to the range on Saturday:



We experienced double feeds with low brass bird shot, but buck and slugs ran flawlessly. One of the guys we were shooting with, who works for Homeland Security, said this was an issue common to Mossberg 930s, that they ran best with tactical loads, not low brass bird shot.

Does that sound right?
