OK, so the wife's brand-new 20 ga. 391 is sluggish with 7/8 and 1 oz loads to the extent that the bolt does not travel all the way back, creating a jam with the empty and fresh shell, or with a failure to eject. Works fine with 3" shells, but we got it for use with standard 7/8 and 1 oz loads. The gun has been cleaned and nothing appears out of order. Just needs breaking in? Suggestions?
