Looks like the Rem 600 but with a box mag.

I have a 600 with a scout scope and it is very easy to carry as
the scope is forward of the balance point and your hand can
go around the rifle easily. Mine is 308, but for those that
wanted a bigger bore or more power it was offered in 350 mag like
the photo in the link.


A slower powder like w760 is most accurate in mine so far, despite the shorter barrel.
