7x65R 7mmRem mag light

7x57R 7x57 is a tried and true round 100 plus years old and has killed everything on this earth.

6.5x57R 7x57 light

30 Blaser 30-06 in a flanged cartridge

30-30 Win

My pick for Deer would be the 7x57R but if I was going to shoot anything bigger the 7x65R.

What kind of rifle?
