Yeah I don't know why it doesn't like them. All this time I thought it was 2 3/4" shells when in reality it's just Winchester ones it doesn't like. Now I'm not sure about the random jamming it does with 3" and 3 1/2" as the Winchesters seem to do it less than the Remington shells I used to use. I've tried Federal too but not sure if I've had them jam or not. It seems like you can expect at least one jam every 20 shots with buckshot. Might not happen but you can almost expect it and it seems to be random and something different every time.

I thought about it needing breaking in as I was the original buyer of it but honestly I've probably put 2-500 shells through it. I want to say 500 but it may not have been that many to be honest. Then again it may have been. I shot a lot of 2 3/4" shells through it when I got it. I may have thought a lot would have been 100 or so though. Then I've probably shot 100 or maybe even 200 shells of buckshot through it. I'd think it should be broken in by now.
