Hah!

Your 7.62x64R gave you away..........that was some sort of Russian WWII rifle

and Lapua would sell it as 63R A somethingorother Nagant, I believe?

As I said, the x33 is the M1 carbine round................which was only issued to officers on the grounds that they could damage fewer of their own troops

At least, that's what a certain Gunnery Sergeant Major told me
