Read my post 670951 where I recommended you "measure" the chokes. Very few posters seem to think that is how you tell. A Winchester bored modified and full will show IC and IM on any choke gauge including a bore micrometer. Winchester chokes are notorious for being anemic. If you don't have this bit of knowledge as well as a bore micrometer, you have no business attempting to buy $5000 Winchesters.

You are absolutely correct, eightbore. Coming soon!! Among other things. Thanks! 👍

Interesting, my experience with Model 21's does not match up with eightbore's post. My 20 gauge 21 Skeet with two sets of barrels has skeet 1 and skeet 2 (in and out?) in the skeet barrels and measure tight on my non-micrometer measurement tool with the tighter barrel approaching modified. The other set of barrels which are marked M/F provide readings at tight modified and full. I wonder if these measurements are a result of the age of the gun (1948) thus the use of fiber wads? I anticipate that modern plastic wads may result in tighter or at least denser patterns.

My trap grade 21 12 gauge has barrels measure light full and full consistent with the markings on the barrels.

Thus I don't think these are anemic constrictions.

Schwings Model 21 book indicates that Skeet #1 has 87% of the pattern in a 30 inch circle at 20 yards and 33% at 40 yards. Skeet #2 is reported to have 93% of the pattern in a 30 inch circle at 20 yards and 50% at 40 yards. Skeet #2 is reported to provide the same shot distribution at 30 yards as the Skeet #1 at 20 yards.

After writing this I think one reason I miss the high going away shot in 5 stand is I am shooting the wrong barrel at that target.

That brass gage is useless for choke. I had a 16 ga. that the barrels were cut, someone took one of those choked gages and it stated full.
First, if you don't know the bore than you won't know the correct choke.

I have a Skeets gage that can read 16" into the barrel, read what it states then zero it and read the constriction. If you are not math-challenged, don't zero it, but I do.

Right, David. That is what I said in my post. I measured a couple that showed I/C and they were Modified chokes from Beretta. Or the likes. At least two of them that I measured and were factory--the gauge was way off a couple steps. I did measure a Browning, Ithaca 37 and Remington Wing master and all four were 20 gauges and the same on the gauge. So, I figured the 21 was full choke. The guy in the store showed me how he measured the chokes with the brass gauge and he didn't read it right. Then he wrote it wrong on the tag. I didn't measure it the first day I saw the gun. I should have. I'll know from now on. Thanks for the info and the help. I appreciate it, David.

Just for grins I thought I would post the device I use to measure choke in 20, 16 and 12 gauge barrels. It is a Frank Mittermeier Universal Choke Gauge probably from the middle 60's. I inherited this gauge from my father and I have found it to produce reproducible results corresponding to known choke in my guns.

Five posts and not one of the five mentions thousandths of an inch either for bore or choke measurements. That is the only measurement that means anything.

I understand eightbore, but there isn't anything more I can do at the moment. As long as the chokes are full and modified like is stamped on the barrels, I'm happy for now until I can get the correct instruments to measure exactly what they are. I just placed an order with Galazan last night for a few things I need. I'll let you know when things work out. But thanks for the advice.

I've had one of those for probably 40 years. Bought it from an ad in Shotgun News, it works well enough for my needs.

I have seen those before, jlb. I think we discussed those on this website years ago. I believe somebody else had one of those. I can't remember who it was, though. Maybe it was you who brought it up before. But, thanks for sharing it with us. 👍
