One Rifle and One bullet? It would probably be my HVA lightweight 308 w/2x7 Leupold and 165's. As I shoot gophers to Moose I would use cast 165's at 1300 fps for goph's and book max loads of I-4064 w/165gr partitions on everything else. Or I would choose my HVA FN Lg. ring 7x57 and 160's as above. Muddy
