In a 45-70 revolver, can 410ga be fired safely?
In a revolver chambered for the 45-70 Gov't round, such as the BFR or Thunder Five, can 410ga shotgun shells be fored safely? (assuming appropriate length for cylinder)
The pressure of the 45-70 is about 28K, way above the 410's 13K. The external diameter of the round is so very close but I am wondering if doing this may damage the forcing cone over time.

This subject is one where it depends on who you ask. I can only give you my advice. Dont do it!! Hope this helps.
Good Luck.

I don't reckon I'd do it cause it wouls give me an excuse to go buy one of those revolvers that is actually made for .410 gauge.

Well, according to :
http://www.calweb.com/~haas/ammoguide/runammo.html
The dimensions of each are the following:
.45-70:
projectile diameter: .458
case diameter (distal, nearest to projectile): .480
case diameter (proximal): .504
rim (vaires, but listed as): .608
.45 Long Colt (no 410ga listed, but if a 410 fits in a 45LC, then these dimensions should help)
projo diameter: .456 (varies I'm sure, as most are .452-.454)
case diameter (whole thing): .480
rim (varies, but): .512
So the 410 ought to snug right in the .45-70 cylinder. Maybe a little loose near the base where the 45-70 is larger, but should hold in place.
Now, that extra space may cause pressure problems and case bulging- which is what i am really asking.
Maybe some of those steel cased 410 shells available would work to holding the pressure? Maybe the tougher 45-70 cylinder (designed for double the pressure of a 410) would be fine in any case?
I suppose that is more specifically what I am asking. Would ANYONE know the answer to that?
I once spoke with the machinist at the Thunder Five factory, who said it would be fine. But I always got the impression he wanted to get me off the phone. So I never did it.
Anyone who actually OWNS (or has owned) a Thunder Five or BFR know anything about it?

Can't speak to the .45-70, but have fired many .410 in one of the combo .45 LC / .410 chambers - big dif in recoil, but that was it. I concur w/ SP, there could be an extraction issue because of the nominal extra 0.020" clearance around the base, and w/ papershells a failure. If I were to try it (and frankly if I had one I probably would), I'd at least start with the all brass shells. I am specifically not advocating this trial, however (with a nod to ATLA). 0 -
All brass shells?
Say, where can a guy find those?
I found the steel Russian ones, but no others.
Hopefully, my buddy with the Thunder Five will lemme know how it goes!
C-
