Is it normal for a Winchester SXP to double feed shells when you don't have a super tight grip on the gun? Ive noticed for this gun to run reliably you must have a very tight grip, shoulder the gun aggressively and cycle the action hard and fast. I know this is the proper way to handle a shotgun but would would this gun be consistently double feeding when not handled like this? My buddy has the same SXP and it has never double feeded under any circumstances. Any advice is appreciated.
