I'm thinking this round is like the 260 Rem.
6MM = .243 doesn't it?
Nice rifle BTW.
than the 243 but you are right about the bullet size. Scarecrow
I bet that baby will sizzle a bullet of the .243 cal.
I guess it could be .243 or .244 cal. couldn't it? Remington renamed their .244 cal. to the 6MM Remington years ago.
