All the labeling of choke and hole counting answers little for the hunter or practical shooter. What a shooter wants to know is; what does my pattern out of this barrel/choke look like at a given distance?
A 30" 75% pattern out of a 410 with #6 shot may not be dense enough for the hunter's needs.
More relavent to the hunter may be: how big is an effective killing pattern out of my x gauge gun with x choke and x load/shot at a given distance.

Less constriction in a smaller bore to produce the same pattern percentage as a larger bore, as mentioned above.
That being said, I'll add the following: From a table in Jack O'Connor's "Shotgun Book", it's quite clear that different manufacturers had very different ideas about how much constriction should equate to which choke designation (full, mod, etc). For example, in 12ga, Winchester used .016 constriction in its mod barrels, Remington .018, and Browning .024. (Generally speaking, if you measure chokes in Belgian Brownings, you'll find that they are fairly significantly on the tight side.)

How I miss the old days.
I spent many years on the drafting boards at the very end of the "Hand Drawn, Hand lettered" era.
Every time I see an old mechanical drawing posted here, I am returned to my youth, where line quality and lettering style were my existence. All gone forever.
Thanks Researcher.
Out there doing it best I can.

Gentlemen: Thank you for all of the responses - my question, which might not have been composed as well as it should have been, has been answered. When the weather in my area allows, I will do the pattern testing suggested.

Technicaly yes.
However take the skeet choke that most people use is .005 for all the gauges. Some people use tighter chokes on birds in the small gauges for the same reason.

To elaborate further, skeet choking goes against the grain. Shooters often employ as much, or more, constriction in their 28 than with their 12 (if they even use one!). This is because the endpoint is not pattern percentage (choke) but, rather, pattern density......at 21 yds.
As a corollary - because there are no free lunches - they must give up pattern diameter to maintain density. They choose to do this because they do not need a 30" circle to break 100 straight, and because they cannot abide a statistical glitch whereby a target gets through an overextended core.
You can have a "no-fly-through dense" 12 ga 1.125 oz pattern of around 30" - but you won't do it with 3/4 and 1/2 oz payloads.

Especially not 1/2 oz. You see some pretty high scores with the 28. 100 straight with the .410 is less common.

I own a Beretta 20 gauge Model 682X Trap that has .035 constriction in both barrels. They are marked improved modified and full. I have owned a Merkel 200E 12 gauge with .055 constriction in both barrels.

Sam Yeah Sam, that's what I was trying to say.
