Galazan's gauge that measures from 28 to 10 is not cheap, but does the job of two Skeet's gauges and barely measures 8 gauge bores, I think. By the way, Skeet's gauges are once again available.

To clarify my earlier post, the gauge I described is a $500 gauge, but well worth it.

Thanks, I bought one from "the unloader" (Gary) and so far it seems like a good gauge. However, I am going to add an adhesive tape measure to the rod to accurately identify the start of the "choke". Then, practice, practice, practice... A certain amount of the "reliability and repeatability" of a gauge depends on the user.

"THAT" is a true statement. Not everyone is a talented machinist, but it helps when measuring bores.

The Brits give each quarter ten thousandths. Ten to forty, ten being a 1/4 choke.

When measuring the "points of constriction" it's easy to establish the inside diameter of the barrel. The tricky part is measuring the "choke" at it's narrowest point. When you guys measure the end of the choke, do you try to catch the measurement just as the gauge is popping out of the muzzle? Or, do you measure inside a smidge, like 1/8" from the end or something like that? I had my gauge with me at Hidden Hollow. I should have compared techniques with a few of you. Jeff
