My daughter has a Winchester 1400 in 20 gauge that has been great for her. However, this year at our dove hunt, she kept having jamming problems. Once a shell would fire it appeared like the bolt cycled without ejecting the spent shell, so that we would have a new shell on the carrier and the spent one in the chamber. It was a bear to get out, I'd have to use a screwdriver to push the fresh shell back into the magazine before I could get the spent shell out. Does anyone know why this is happening? I was on almost every shot. It also happened whether she shot or I shot. It was very frustrating. Could it be just a lube problem or something else? Any help is much appreciated. Thanks.
