It is nothing like the 45-70. Firstly, it was designed from the onset to be shot out of a Winchester lever-action 1876 'Centennial' rifle or carbine, in 1879. It was intended to fill the gap between 44-40 and 45-70 Government - as a deer-getter. It was discontinued by the only factory making it back in 1935. The firearm lasted in production only until 1897.
It was also used in two other 'weak-action' firearms - the Kennedy lever-action repeater [the what?] and the Colt Lightning pump-action repeater....
Ballistics -
45-60 - 1315fps - 1152 ft lbs
45-70 Black powder - 400gr lead - 1400 fps - 1306 ft lbs
45-70 Nitro - 300gr SP - 300gr SP - 1880fps - 2355 ft lbs - Ruger No 1 or modern nitro-proofed arms only - NOT ANY type of Trapdoor Springfield
45-70 Nitro - 405gr SP - 1330fps - 1590ft lbs
None of them is an elephant stopper.
The general consensus is that a minumum of 3500 ft lbs is needed for elephant.
But please feel free to prove me and generations of African shooters wrong!
Can we watch?
