I was wondering if you could make a 3in chamber a 3 1/2 chamber by changing the breech bolt assembly. and what is the difference between a 870express barrel and a 870exp supermag barrel and if there is a difference would a 870exp supermag barrel shoot 2 3/4 - 3 inch shells different than a regular 870exp barrel?
