I've taken a few hogs over the years with my 30-06 browning and norma vulcan 180grains

Now I'm feeding the rifle with hornadys 150 grain Interbond- That bullet is one hard hitting M*F.

Got 2 scopes mounted in Leupold QR. A Aimpoint 9000L for those driven hunts and a Zeiss 6-24x56 illuminated for those dark nights. You do not really need bigger than the 30-06...
