3 inch to 2 3/4 sleeve ????
I am building a mossberge to shoot at turkey shoots with modifications ive made so far am winning meat, but I stumbled on an internet article some time back of someone talking about a sleeve to shorten the breech from 3 inches to 2 3/4 inches to give just a small bit more of barrel length for possible improvement in accuracy anyone heard of or know where i can find info on this thanks,
