Cartridge Case Headstamp - 303 ?
Looks like a .303, but I don't have one around for comparison. I've got a .45 Mag kicking around somewhere, but that doesn't really help much, does it?
I'm getting 57mm from mouth of case to bottom of base for mine, yours looks longer, might might be because you took the photo so close.
Just measured it with the micrometer and the length is 56mm
and 7.93 opening diameter.
So a 303.
