BRIDGE .410
I trolled this one a couple weeks ago. The firing pin was sticking out keeping it from closing every time. Easy fix. Made for a big hardware store in St. Louis, until 1930., by Crescent arms. Several barrel makers. The 12 mm choke is tighter than the .410 Stevens I've got by a good bit. Elmer Fudd would be proud. I'll give a pattern report.

Leave it as it is. The ages have been at work on it and man can only mar it.

Re: BRIDGE .410
Yea Man
. What ? Killer idea ? The 12 mm must be O.D. at the muzzle, a 12 mm wrench will almost slide on. It shot about a 2' spread @ 25 yd. with Remington high brass 3" #6, some cheap lo brass #6 the same. I want to get some bb loads and try in it." There are two kinds of people, the good people and the ones that aggravate the hell out of the good people"
Re: BRIDGE .410
Sounds like its choked about Modified, maybe Light Mod.. Miking the muzzle should net you about .390-.395, if the bore is truly .410. Nice little knocking around the woods gun!

Re: BRIDGE .410
I borrowed an old choke gauge that gauges the Stevens right on the .410 mark (full), the Bridge is a little tighter. Extra full ?

NEAT!!!
Damn, I'll bet that's going to leave a mark! Probably hurt too!

Re: BRIDGE .410
What is the constriction? A bore gauge measures constriction by measuring far enough down the barrel to get the actual "cylinder bore" size, and at the muzzle, and the constriction is the difference.
Here is a chart that shows what I am talking about:
https://www.royalarms.com/wp-content/up ... e-size.pdf
This is a bore gauge:
https://www.trapshooters.com/threads/di ... ed.884971/
So per this chart, your Stevens is Cylinder bore. (hence the name of the cartridge, '.410 bore' )
For instance, My Ljutic Trap gun is backbored to .740, and the dia. at the muzzle is .705, meaning it has a constriction of .035, or full choke.
To measure true constriction you would have to use the device I mentioned. Some call other instruments a bore gauge that aren't, like a micrometer, or a 'wedge', or dime.
Assuming the true bore diameter is .410, per the chart, to be a full choke, the muzzle would have to measure .395. I was a little off on my guess, but I rarely deal with .410's, usually 12 ga.
