I fondled an empty .45-70 case and tested its fit in several magazines. This seems like it would be a NICE round for the AK platform.
I am sure it will fit in the G3 .308 magazines I tested. I still have a pile of them! The FAL mag would require a bit more work to shape the top area due to the thin size, and it would hold less rounds, again due to the thinner size. My estimate is that perhaps 12-15 rounds in a G3 magazine would fit.
The PSL mags are really too thin at the tip to handle more than perhaps 5 rounds, if that much. I think the cartridges tip too much toward the middle, but I'd have to stack it full to see exactly how that would work.
I didn't have any other mags - PSL, FAL, and G3 were all I could find. I'd like to see how those US Saiga .308 magazines would work. I wonder if Saiga .410 magazines might work too?
Looking at the rim, it seems a 7.62x54R bolt could be modified to fit the .602" base of the .45-70. There would still be enough area on the bolt to cover the rim, and considering the rim really doesn't need to be directly supported, it seems almost too easy to modify it.
The Speer reloading manual has a section dedicated to the .45-70 with loads specifically tailored to "only the modern lever actions" that can handle the "extremely high pressure" of 35,000 CUP. That really got my attention!
The AK action should be able to handle this cartridge no problem.
considerable hunting platform. And a home defense platform too, assuming you put a big muzzle brake on it. I'm thinking a blast-redirecting brake like on the Barrett 50. I'm pretty sure I've seen one of those, perhaps on Global Trades.
I have no idea on barrels. I assume it uses a .458 barrel but I could be wrong. I'll have to check on what's out there. I think a nice 16-18" barrel with a whopper muzzle brake would fit the bill very nicely!
Wheels are a'turnin!!!! Someone talk me out of this! Why would this be a bad idea?
