... I use a Skeet's bore gauge. I do all right with it on wild Bobwhites though. ...
Mike, I've never hunted wild Bobwhites. But they must be pretty easy to hunt if you can use a bore gauge to take them. (or are you just measuring them?) I heard those dogs of yours were really good. Maybe that's it?

Chuck you misquoted me again! I wish you would get your facts straight.
My dogs have been known to catch a pen-raised Bobwhite during a field trial.
And of course what bird dog owner would ever challenge the statement "I heard those dogs of yours were really good. Maybe that's it?"
Best,
Mike
I am glad to be here.

I have no actual facts to back this up, but it would seem to me that to throw similar patterns from the various gauges the constriction should be proprotionate to bore diameter, IE the reduction of area be the same. Lookung at various factory specs for chokes over the years has revealed they generally & loosely somewhat follow that pattern.
Based on this constriction of a 28ga equivelent to a 12 ga would be as follows;
12ga------28ga
.040"----.030"
.030"----.023"
.020"----.015"
.010"----.0075"
.006"----.0045"
CYL-------Cyl
Note the constrictions for the 12ga are essentially the "OLD" card & felt/fiber standards for full, 3/4 (Imp Mod), ½ (Mod), ¼ (quarter choke), Imp Cyl & of course Cyl is 0.000 constriction though anything .003" or less is often referred to as Cyl. It is also noted that many US shotguns over the years stamped IC have traditionally carried ¼ choke constrictions. Many makers of course also varied some from these exact standards.

Lets not forget that the "small" gauge patterning is done at 30 yds while the 20 and up are 40 yds.

The 28" barrels for my 28 repro were choked .034/.043. Had them opened to ..008/.018. Not worried about resale value. I had a 16/20 combo with Krieghoff barrels. The gun was really nice with the 28" 16 barrels but did not balance well with the 26" 20 ga barrels. It was a single-trigger gun and I never had a problem with it.
Given the price the 16/20' are selling for you can probably find an original 16 ga DH for close to the same price except if you are looming for a gun with a straight stock.
Around the steel no tortured worm shall twine.

Man! How did this happen? I remember a couple years after they hit the marketplace they started getting bad press/wor do mouth. If I can recall, the stocks were cracking at the wrist? I don't think you could buy one for more than a couple, couple and a half dollars

Larry, My original unaltered 28-ga. Repro chokes, carefully miked by a professional using a professional bore gauge is as follows:
Q1/Q2 = .004/.008
IC/M = .006/.016
M/F = .014/.034
We all know that actual constriction doesn't tell the whole story, you have to actually do some empirical pattern testing with various loads to determine what kind of pattterns your particular gun shoots, right? In your post above you never admitted that you actually shot your M/F choked barrels to determine effectiveness. It would also seem that either:
a) The chokes on your guns were mismarked.
b) You used inferior equipment to measure the chokes.
-or-
c) Operator error in measuring the chokes.
...and since you weren't able to even get the gauge into the barrels to measure them, it leads us to come to only one conclusion. Darn WS . . . I've seen "professionals" using the same Skeets gauge I use, and I've seen some use other gauges. I've checked the readings on mine against the readings they got on theirs, and I've never come up with more variation than about .001/.002--and that's plenty close for government work. Using a bore and choke gauge ain't rocket science. If you zero the gauge correctly to start--and I always zero mine before using it--it's about as difficult as walking and chewing bubblegum simultaneously. The fact that your chokes did not read exactly what mine did (please note that one other poster came within .001 of my readings) is neither here nor there. No guarantee they will be the same on every gun of the same model and gauge. That's why it's a good idea to use a bore and choke gauge! Same deal with stock dimensions. Most Repros have little or no cast, but I've run across a few that have a fair amount. And are you suggesting that a 28ga ought to have even .034 constriction for full choke? If you do, that's interesting . . . because I have a set of Briley thinwalls for a 12ga, and the full choke tube only has .030 constriction. It'd seem you disagree with Briley there. And you can only draw one of two conclusions when a bore and choke gauge won't go into the muzzle: either the gun is severely underbored, or else it has a whole bunch of choke. And since the Repro 28's I've measured have all been slightly overbored--in the .555 range vs the standard .550--that pretty much leaves a whole bunch of choke as the only possibility.

Maybe not, but it's a pretty good indicator about what's gonna happen before you light it off. A common choke constriction with a common profile and a common shell is more'n likely to give a common result, less they not be able to mass produce these things.
