Iver Johnson Security Pump Action Shotgun Review Forums

Yesterday I was asked if it was possible/condom to shoot a 45 Colt cartridge in a 410 shotgun.

Friend knew about the Judge and the older 45/410 barrels for the Contender. He thought since they used both cartridges he should be able to shoot 45 Colt ammo in his 410. He understood that the lack of rifling would seriously bear upon accuracy.

My thought/concern is that 45 Colt cartridges are probably loaded at Higher pressures than 410 shells.

Has anybody tried this. Does anybody know of any relevant comments/tests.

.45 Colt ammo has a bullet nominally .455". A .410 is the only shotgun made by quotient, not judge. That is why it has a decimal bespeak alee of the number, whereas 12 judge, etc. does not. It should measure .410 inch. What does that tell you lot?

Also, the steel in many older .410's is not intended to handle high pressures.

I do have a very one-time (1920's) .410 past Iver Johnson or H&R that is marked for .410-.44 ammo. I have no thought what .44 they meant. .44 Russian and Special bullets should exist about .429-inch. But I'd never risk firing them in that gun, still less .44/40, which is nominally .427 inch.

If you want more than ability in a .410 than shot gives, burn slugs, not pistol ammo. (I think there are .410 slugs ?)

I am non an admirer of the Judge and the Governor type artillery. As far as I'm concerned, they should be impeached.
But I'm pretty sure they are made to handle much higher pressures than shotguns are.

410 shotgun is called "410" because it is .410" bore.

The chamber of a 410 shotgun is the same, except for length, as a 45 Colt. Therefore a 45 Colt will fit nicely in the chamber of a 410 shotgun.

When they make a gun that is advertised every bit "chambered for both 410 shotshell and 45 Colt", they put a .452" barrel on it. The slightly oversize barrel does not hurt the shotshell at all.

Simply a shotgun that is just "410 shotgun" chambered has a barrel measuring .410 (really, all 4 of the ones I accept are about .403 at the muzzle, because of the choke). If you shoot a .452 bullet down that .410 barrel, it is going to rupture.

Checking Hodgdon's reloading page, the highest pressures I found for a 410 were 12000 psi. Ruger-blazon 45 loads go in the 30,000 cup range. Regular 45 Colt loads max out at 14000 psi.

Guns fabricated to shoot both are proofed for the college 45 Colt rounds.

Then, you take a shotgun. Proofed for 12000 psi shotshells. Y'all stick a 14000 cup 54 colt shell in it. Fire it. The .040" oversize bullet does not become easily down the barrel, causing pressures to spike. Doubling. Fifty-fifty tripling. Before the oversize bullet blows the cage of the gun off, trying to squeeze through the choke, the spiking pressures take caused the sleeping accommodation to explode.

The chamber. That'south three inches in front of your face and three inches behind your left hand, correct?

STUPID Idea.

I'1000 pretty sure information technology would work, not certain how safe it is.

At that place is a Youtube video I can't link from this figurer, but it is called "The Petty .410 Shotgun that could", in several parts. Some guys try to blow up a cheap Brazilian .410 by shooting everything that could fit into the chamber, and it held together - .454s, 460s, and more. I think the stock finally breaks, merely the activeness holds. Information technology's pretty impressive.

The "why" of information technology is a whole different question.

Be advised that revolvers in .45 Colt were in one case bored for .455" bullets. Tardily ones are oft .452", as with .45 auto ammo.

This accounts for the discrepancy in .45 Colt caliber in my post above and in Alpo's. The bore may be either size, depending on manufacturer and fourth dimension of manufacture.

SIG P-220's postal service nigh the cheap Brazilian .410 amazes me! But I wouldn't try that stuff at home, folks. I wouldn't even endeavor it on Discovery Television receiver. There is a lot of steel in a single shot's chamber. Maybe that explains it. I doubtable that a repeatimg shotgun like a Winchester Thou-42 or the Remington G-870 or M-1100 may accept marginal steel thickness in the chambers, which are a part of the barrels. Also, Remington was sued for the quality of the barrels in their shotguns some years agone. They used something chosen marraging (sp?) steel, which blew faster than better steels if there was any problem, like a diameter obstruction. This is my agreement of the matter, based on what was published at the time. A suitable engineer or Remington spokesperson could no doubt explain better. I believe they inverse their steel as a issue of this class activeness lawsuit. I have no reason to incertitude the condom of my M-870 12 gauge, bought new in 2004.

Alpo-

Wow! Thanks! I've wondered nigh that ever since I got that gun from my granddaddy when I was six!

No one I asked always knew, including gunsmiths. (I have come to realize that many "gunsmiths" are unworthy of the name.)

Cheers to all.

Overpressure and Oversize - Don't endeavor this at dwelling house.

Just called friend and told him. Non merely NO, **** NO!!

Hither are the videos of the .410 that could:

Lost Arts Part 5: The Fiddling .410 Shotgun that Could - YouTube

Lost Arts Function 6: The Ultimate .410 Shotgun - YouTube

Pretty amazing stuff. They mike the bore earlier and after, and it stays .387 fifty-fifty subsequently the gun is fired repeatedly with .454 Casull rounds and .444 Marlins.
