My rem 870 express super mag 3, 1/2'' chamber is jamming on almost 1 in 3 rounds with the cheapo winchester walmart rounds. I used to always use them with no problem; then I switched to federal for awhile, and now that I switched back my gun hates winchester.
Basically the shell is getting jammed in the chamber and will not eject out when pulling back on the pump action.
I tried a mild polishing with some steel wool wrapped around a cleaning brush on a cleaning rod to no avail - I have seen some people online go at it with a dremel brush is this a good idea? Does anyone have any other possible causes?
Thanks.
