I have been looking for a Hunter Arms Co. .410 double to shoot at our events and finally came across a Fulton Hunter Special .410 Gun is in very nice condition, with 26" barrels (all 295 Hunter Specials had 26' barrels). I measured choke constriction with a small hole gage and then miked it, the right was .397 or .013 constriction. The left was .380 or .030 constriction. I made a plug gage from aluminium .4086 to check diameter of bore. It went in with a little drag so I'm guessing bore is .410. Everything I tried to find on choke constriction for .410 listed .022 as full. I know I am going to have to pattern this and what is a good distance, I've read 30 yards. I know it is usually 40 yards at a 30" circle but for a .410 everything seems different.
I know that all L.C. Smiths were patterned at the factory and on the hang tag gave the choke constriction, but I do not know if the Fultons were patterned, I would think they would be but can't say for sure.

I use .002 for skeet, super pattern at 22 yards.

I had a late uncle who shot .410 at thousands of quail. Left barrel was choked at .030. He used a 3” shell in that barrel and used it on only long range birds. Funny thing is that I clearly remember him a asking a pair with his second barrels several times. I patterned it and found any shell over 1100 FPS had poor patterns but s 3” shell moving at 1100 FPS had decent patterns at 25 yards.

This gun is chambered for 3" but for right now I am reloading 2 1/2" at 1200 fps and another at 1220 fps. I will try both 30 yards and 25 yards to see what it does.

I have a new FAIR Iside Tartaruga Gold .410 that came with five screw in choke tubes. Both bores measure .409". I have not had the chance to pattern them yet, but the constrictions measure:
C - -.006" IC - +.003" M - +.012" IM - +.023" F - +.034"
It will be very interesting to see what they show on the plate.
My Dickinson has tight bores at .399" and .398" with fixed chokes that are ..008" and .008". They have worked very well for me on doves and quail for three years running.
My Yildiz has fixed chokes and bores that measure .400" and .399", and chokes are .011" R and .015" L. It works great on dove and quail, too.
The Verona O/U is bored .410" and .410" and is choked .004" bottom and .011" top. It has worked fine on doves, but never used it on quail.
All pattern well, so the jury is still out for me on what suits me best. Sorry I cannot be much help at this point, but I'm having fun figuring it all out, and killing lots of birds in the process.

My tightest skeet choke .410-bore is my pre-war Model 42 with .006". Other skeet .410-bore barrels I have are .002" (2), .004" (2) and .005". My .410-bore spade for my bore mic won't go in the full choke barrel of my Winchester Model 23 Classic, but I finally ran into one that would and that choke is .028". The Ithaca Gun Co. Standard Bore, Chamber & Choke for Shotguns drawing and tables gives .020" for a .410-bore full choke, but my NID has .024".

Traditional .410 pattern distance was 25 yds per O'Connor, anyway. Somewhere in his writings he said that's what the folks at WW-Olin told him. That was before shotcups.
Your 0.013" bbl is about like my repro's 0.014" ("IM") Briley tube. Kinda strong for a skeet field. I use it for SC. A centered 30 yd midi or battue kinda dissolves with #9s or #8.5s. Most any 2.5" best quality domestic shell in #9 or #8.5 can make a case for 30 yd patterning, in accord with what you've read. IME, Win 3" #7.5s would merit 25 yd testing. I'd wager the 3" RP equivalent will be a 30 yd shell through your 0.013.
Dunno what to make of the the 0.030". My Win .410 "full" bbls run from 0.016" to 0.020". But I can't call them legit 35+ yd barrels. One exception is the RP 3" #6. Through a "full" 42 I get a % in the high 60s at 40 yds. In fact all the pellets fall within about 20-22". There is no "outer ring". Not quite sure what to do with it, though. Don't figure on taking 40 yd pokes at ditch parrots with it. Probably great for road-wrenching grouse.

While you're patterning it check the barrels for regulation, David. It's just something you cannot assume is right. Most vintage guns are, but not all. The .410's regulation is affected more by how tightly/loosely you hold the gun, than are bigger and heavier bores.
Hope you enjoy it as much as I do mine!

Thanks to all, I just didn't know what to expect with those readings after seeing what some one had posted that .005 was considered modified from the same article that Samuel posted about what O'Conner wrote.
Full Choke, .410, .396, .014, 70 percent of shot in a 25” circle at 30 yards. Modified, .410, .405, .005, 60 Imp. Cyl., .410, .408, .002, 50 Cylinder, .410, .410, None, 40
This is what I copied that someone had posted on another site.
I will have to see how they pattern myself. Have plenty of choices for 2 1/2".

The "Old" 12 gauge standard for full choke was a 10% to 11% reduction in bore area for the choke. This gave a constriction of from .038" to .041". This same % of reduction in the .410 would give constrictions of from .021" to .023".
