    Quick answer? No. Though Tony Rumore converted a Saiga .410 to .444 Marlin. And some AR manufacturer makes a .308 pattern AR into a .450 Marlin but I've got an expert opinion that says feeding can be problematic.

    If you want a semi-auto throwing large chunks of lead look into a Rock River Arms .458 SOCOM, Bushmaster .450 or an Alexander Arms .50 Beowulf.

    Very true, but it was a dark day, because I didn't get to shoot it.

    According to the Zombie Survival Guide, no, not currently.  But just because it hasn't happened yet, doesn't mean it won't happen ever, so I second what Raptor said.

    I would imagine that the individual viruses don't discriminate between human brain tissue and other animal brain tissue. If they don't, then we're all doomed and need those rifles. If they do discriminate, well, we need those rifles anyway. ;D

    Might be possible to modify an SVT or PSL. The rim of the 7.62x54R is .570", while the .45-70's rim is .608". With a difference of less than 1/32" in diameter (1/64" in radius), it could possibly be done.

    Who's going to offer up their rifle for experimenting?

    NOT IT!

    Heck even if it was a new version of the 45/70 i.e. same bullets, I don't care what it's called as long as it's not from Alexander Arms.  Something that each of the ammo companies would make some for, so ammo would be available.  And give us 15+ rd mags for it!  preferably 20+

    A 45-70 likely couldna be made fromma Kalash. But perhaps some species of Dragunov could be bred te do the trick. The receiver's fair long.

    But a PSL is far more Kalashnikov than Dragunov. A lot less spendy too.

    To my understanding the big holdup is the cartridge length in regards to 45-70 and the fact that it's a rimmed cartridge right?  

    So how much shorter would it have to be to fit either, or both, the AR family and the AK families?  Ok and then get rid of the rim.  

    Call it 45-70 Auto or .457A or .457badA

    The lost in length, what kind of change in power levels would we be looking at?  Enough to matter?  

    It seems you'd gain a lot, unlike going with a new bullet or style etc, using existing bullets of the .45-70 family you get a lot more options for reloaders and custom runs right off the bat.  

    Thoughts?

    That brings up a good question.  Does anyone know of any Dragunov like weapons chambered for anything other than 7.62x54r?  (and that's actually available and doesn't cost a billion dollars?)
    UtahIt doesn't cost me to be nice, but nothing gets you nothing and everything's got a little price.

    Well, if you took a 45-70 and shortened it to fit in an AR, lost the rim and made the case a little fatter to replace lost case capacity you would have just recreated the .458 SOCOM that's been around for nearly a decade.

    So the .458 uses the same bullets as a 45/70?  Interesting.   :hmm

    Anybody have any ballistic data comparing the 2?

    458 SOCOM factory loads exceed Remington or Winchester 45-70 loads by a fair margin and are reasonable close to what a handloader might safely achieve in something like a Marlin Guide Gun.  For example, CorBon claims 1900fps for a 300 grain JHP from a 16" barrel.  I get 2200 fps from a 22" barreled Marlin 1895 45-70. The SOCOM runs a 405 grainer about 1700fps from a 16".  I get 1875 from my Marlin with 6" more barrel.
