    What was the normal bore dia.on these barrels? I have a friend that has one and we are trying to figure out how many thousands of choke it is. The end is .6925 so if it is .740 that would be.0475 of choke and that sounds very tight to me.

    Mine had a constriction of .042" and I had it opened up to .034". Don't remember what the bore was but .737" sounds about right. The choke was just too tight with STS LH8's and my reloads which pretty much duplicate the STS loads.

    .690 dia. at the end is equal to a x-full choked gun according to charts.
