I think your decision to go .308 is a good idea. Why pay 30-40 dollars a box for over powered ammo when you can find .308 in a hardware store next to the 30-30 and 30-06. your .308 will actually rise 3" at 100 and 5-6 " low at two hundred. Get a heavy bullet known for expansion and start...
I hold a grudge but also believe that what goes around comes around. You wait for someone's stupidity to work against them w/o a person wronged even becoming directly involved.
