I've found a pile of bullets lately but nothing like this one. I can't find my caliper set but it measures roughly in the mid-40's caliber wise. Maybe it's not actually a bullet but had some other use. Any info would be appreciated.
Probably much more common down here in the U.S. than up in Canada.I thought at first that it might be from a .455 Martini Henry(a british rifle since youre in Canada),but the .455 doesnt have the rings and is paper patched.
