Re: Choke Tube Constriction ?
A standard 12ga bore is supposed to be .729 in diameter. Problem is each manufacturer has their own idea of "standard". Whatever the Remingtons mic out at, Nitro has probably found that .670 is the ideal diameter choke for that set up. Another brand will probably get a tighter or looser recommendation.
