[QUOTE="antelopedundee, post: 1925277, member: 107384"] If you intend to keep the rifle I wouldn't mess with setting the barrel back; just re-fire form and shoot the thing until it's shot out. Size and expand the case neck .001 under bullet diameter. With no primer seat a bullet long in the case. Chamber this dummy round in your rifle. It may take a small amount of effort, but it should go. Extract the round and you should now have a round that is seated to touch the rifling. Seat your bullets in your loaded rounds about .002 or so longer and maybe with a bit more neck tension. When you fire them you should have a case sized to the rifle's chamber. The idea behind seating to touch or lightly jam is to keep the case from moving when the firing pin hits te primer so that all of the pressure is directed forward. [/QUOTE]
