I shot a 12ga M24 quite a bit when I was a kid. My uncle payed a whole $25 for it at a farm auction. He wouldn't sell it to me but I was allowed to borrow it anytime I wanted to. I killed a bunch of birds with it but I'd be lying if I said I never had trouble with the extractors. Some brands of shells were worse than others but it was almost a given that you'd stick one every now and again. The antenna on the pickup never failed to knock them loose.
