October Country made a 4 bore
A 4 bore is about a 1.00 caliber ....1400 grain ball...
but these are/were muzzle loaders and very costly...
Tropical hunting rifles...
Hughes...Robert, not Howard made a 4 bore as well with 1800 grain bullets
a 4 bore is a monster...dwarfs a 600 or 700 Nitro...I cannot imagine
and some of these are cartridge puppies
these guns typically cost as much as a fancy Clayton Double Wide and up....way way up...if it looks British or Austrian or German...fuggedaboutit
Wouldn’t a “4-bore” shoot a 1750-grain ball?
