400 Whelen maybe.

I do not see a belt but I am just on my phone.

Not enough taper in my opinion for the H&H. Also looks like a medium rim IE .473

It is definitely not a 9,3 Mauser... the bullet is clearly bigger than 366


If you are not actively engaging EVERY enemy you encounter... you are allowing another to fight for you... and that is cowardice... plain and simple.
