My T3 Lite is only 7 1/2 lbs with a scope and with a rest I can print nice groups at 300 yards. Its also a 30/06, so I would bet that a .308 would be even more accurate. I used to lug around a old Grampa gun that wieghed around 10lbs, and after a full day of hunting, and bushwacking, it sucked.
Carrying my T3 Lite feels amazing. I often catch myself smiling to myself thinking about how much nicer it is to carry then my old Grampas, wet wood rifle.
If I was planning on using a rifle strictly for competition target shooting, then I would get a Varmint style rifle, but unless you hunt with a ATV driving up and down logging roads I would'nt want to carry a 10lb varmint rifle for moose or deer hunting.
