Loaded up some Missouri 180gr hard cast over 9.3 grains of Blue Dot (Plinking Loads). The issue I had was after belling the case it seemed when I loaded them they bulged the brass quite a bit, even made it difficult to eject a live round from the chamber. Any idea what would cause this? Maybe the bullet diameter is larger then .401? Any help is appreciated, can upload pictures if needed. Wanna kill these ads? We can help!
