In all half-seriousness... I'd like to have an M1A. Save the good optics for bolt guns and use the extra cash to buy a lot of ammo and magazines. Not sure if you'd be picking them (varmits) off under 300 yards, but you could certainly cause much havoc within that range if they decide to organize into a heard or something.
If you gotta be at the 1000 yard mark, I'd take a .50 BMG just for kicks or the .300 winmag like someone mentioned.
