I am thinking about buying a 7mm-08 barrel for my encore. I would like to use 162 amax. I would like a 500-600 yd rifle for deer. I am also condidering a .280 barrel. 1. Would the 7mm-08 with amaxs be my best bet. 2. Is the 7mm-08 enough gun, or would the .280 be better suited. 3. I want an accurate, compact 500-600 yd deer gun. I think the 7mm-08 would be tough to beat. Am I missing anything here?
