my 870 but only when it was extremely cold. And only when I loaded it with shells from my pocket. I was suspecting that condensation was freezing the shells in the chamber but then thought there is too much heat and expansion of the brass for that. I also thought it was roughness in the bore. Again - nope.
So I stripped the entire gun down. Took the bolt and if you look there is a plunger that holds the extractor in place. I took a small screwdriver and pushed it back and lifted out the extractor. Then eased the plunger forward.
I thoroughly degreased, cleaned and lightly oiled the bolt and re-assembled and got rid of the problem.
A word of advice - it is best to r

What shells were you using?
Remingtons seemed to be the worst. I don't like them and neither does this gun which I thought was odd. I switched to Winchester I've shot the Super X in the silver box but mostly shoot the Supreme X 000 buckshot in 3" and it does it with both of those too. I've also shot Federal shells too. I think those are the 3 I've shot. I may have to try taking it apart.
