I actually have an idea what those gizmos are...and going along with that when you start measuring for accuracy take into account just how long can I hold my hand perfectly still to get a "solid" reading? and what is the temperature of the room I am measuring in, how do I take into account thermal expansion, does it matter ? well yes and no, and yes and know.. depends on the kind of tool you use to split the hair and the type of surface finish I have achieved in my final process. Lots of variables to consider. ..as has been stated by others, that thousandth or two won't matter much if I point and shoot straight. I am always humbled by the fact that the Parker gun is such a Marvel of metal and wood, balance and artistry and has been for well over 125 years....I am still studying but I should get back to my chores..Happy Easter to All...Thanks & Best,Paul

Bill, just so this thread doesn't become inundated with technical jargon..I'll pm my email address. I'd be happy to help you sort through and identify the various items if you'd like.

I just measured a 20GA two barrel set that I just bought and it measures as follows:
26 inch barrels = RT .618 bore .010 Constriction, LT .617 bore .016 constriction 28 inch barrels = Rt .617 bore .016 Constriction, Lt .617 bore .035 constriction I've always been impressed by how consistent the bores measure on these guns with very little variation. 26 inch barrels have 2 3/4 inch chambers 28 inch barrels have 3 inch chambers and both marked properly |

Welcome to the forum Steven! Congratulations on your 1st post and your new-to-you 12-ga. How about doing a little show & tell in the "Let's See Some Wood" thread", please?

In the first post, Bob had the 12ga ic/mod at 6 and 10. Is that typical for all the 12ga repro's to be that open?

All of the 26" Ic/M barrels I measured were in that range.
