Wonder what these fellows would call:
a 60 - 60+ cal.
a 72 - 72+ cal.
Guess they should go back a bit further in history to see what the calibers of rifles were used in the American Civil War.
Go back a bit further in history to educate themselves on the 70+ calibers rifles used in the American Revolutionary War.
The .577 (.58 cal)(BP)
Elephant gun? Not.
Lion, Leopard, Tiger,? Yes.
Then again.....truth is stranger than fiction.....they my have found some obscure journal entry....by some forgotten, or unknown, hunter that used a properly constructed paper patched bullet, pushed by a near shoulder breaking, barrel bursting powder charge, who actual successfully shot an Africa or India elephant with it at 40 yards or less.
Or perhaps a person that in a last ditch effort for survival shot killing a charging elephant.
Then again this guy most likely things anything bigger, recoils harder, than a .243 is an elephant gun.
