45/70 in a Taurus Judge

[awg1203r]

Anyone know why this would or wouldn't work in the magnum model?

I use a Marlin 1895 in 45/70 and it would be nice to have a backup in the same cartrige when out in the woods.

Because it won't go in the chamber?

And if it did fit, the gun would blow up.

The 45-70 is loaded to about twice the pressure of the .45 Colt, (28,000 PSI vis 14,000 PSI) which is already higher then any .410 shotshell.

You can buy a .45-70 revolver, though, if you want one.

The thing is, you don't really want one. You might as well just carry a second carbine.

Just carry a revolver in a revolver cartridge.

This "shared ammo" idea that people have seems to be going way too far.

.45-70 won't chamber in .410 or .45 colt. Case is too big.

If you want backup in your rifle cartridge, Magnum Research makes their bfr's in several large calibers.

Good luck

The BFR is not a great carry gun, though.

And I'm saying that as someone who owns a 10 1/2" Super Blackhawk -- with a holster.

It's stainless, so you could use it as a field expedient boat anchor.

You could also use it to pound stubborn tent stakes, to club big fish, as a "cheater bar" when changing a Jeep tire...

Endless uses for the outdoors!

Ay yi, holy crap. Fortunately for people with ideas like that, .45-70 is too wide, as mentioned.

To be precise, .45 LC case diameter specs at .480" and straightwall, while .45-70 is .505" at the rim, tapering to .480" at the mouth.

However, wasn't there a .45-70 "CA-legal" version of the old Thunder 5 which preceded the Judge? I suppose that wouldn't tax the frame or cylinder much more than .410s, as long as you stuck with trapdoor loads (<14,000 PSI).

 

[awg1203r]

that was fast! I didn't realize that the 45/70 was a different diameter than a 45 LC.



"Ay yi, holy crap. Fortunately for people with ideas like that, .45-70 is too wide, as mentioned."

-Isn't that why you RESEARCH before you "just do it".

"oh yeah I'll just stick it in there and see what happens..."

idk, I carried my 7.5" BFR in .500 mag for hours on end with an extra 15 - 20 rounds on me when I was out shooting in the desert.

Then again, i'm 6'4" 350lbs and a 5lb+ revolver aint much to me.

Yep, I own one. They recommend factory .45-70 loads in it.

 

[ArmedBear]

At half your weight, it would make me walk with a pronounced tilt.

My 3 1/2 lb. Super Blackhawk is all right, though.

as long as you stuck with trapdoor loads (<14,000 PSI).

SAAMI spec for modern factory loads is 28,000.

Most standard pressure factory loads however, are loaded to around 21,000, and are safe in trap-doors.

There are no 14,000 PSI trap-door factory loads being loaded by anyone I am aware of.

Yeah good thing you researched it first, though they said the .45/70 wouldn't fit anyways.

Looks like we were both wrong, at least according to Accurate Powder. Their stuff says trapdoors shouldn't get anything much heavier than 18,000 PSI.

I just remember hearing, long ago, that 300 gr jacketed bullets at 2,000 fps are for lever guns only, and 405 gr lead bullets at 1,400 fps are for trapdoors or levers, and that the 405 gr ones were loaded to lower pressure. Those two seem to be about the only really common factory loads.

And according to Alliant again, a 300 gr JHP at 2,000 fps requires 27,300 PSI, and full power 27,000 PSI+ loads shoot a 405 gr lead bullet at 1,600 to 1,817 fps. But 405 at 1400 can be accopmplished with 16,100 PSI.

American Derringer made tham, but I did not see them listed anymore. I have a BFR in 45-70, and I would not want to pull the trigger on a 45-70 Derringer.

Get a contender. Infinitely more useful with the .45/.410 barrel and you can swap barrels for the .45-70 if you want. I have a .410/.45 Colt barrel, but it's mostly just a fun barrel. My deer/hog barrel is a scoped .30-30 and I have a .22LR and a 7mm TCU barrel for it. It's more accurate than ANY, I repeat, ANY revolver ever made in the history of the universe. Well, anyway, if anyone has ever made a revolver capable of MOA at 200 yards, I've never heard about it and I'd have to see it done to believe it.

Speer doesn't agree with them I guess.

The closest fit of a rifle cartridge in the Judge is a 444 Marlin (and the 1985 Marlin is also chambered for that). Those are way high pressure (40K+ PSI), but the bullet is .429 for the Judge's .451 barrel. So it may make a huge blast, the bullet won't be stabilized and may just flop out of the barrel, and it may blow up the cylinder anyway. But, you'll have some fire formed 444 Marlin brass that you can load with wads and shot if you don't want to mess with the 410 shotshell hull.
