have a new sbe11 and it will not eject first fired hull.im using 3 1/2" hevi-shot.I shoot left handed but have rth gun.concerned that gel pad which is made for rt handed shooter may be a problem. most of my shooting is done from a layout blind so the butt pad is not always tight to my shoulder when fired. i would think that it would still cycle that way but mybe not. please advise im very fustrated.
