My go to is a Cooper Phoenix in 6.5x284 with a Leupold 6-20 VXIII mounted on it. Using 140 VLD Berger bullets it is a laser beam.

After that I mostly use a 223 Sako stainless laminate with fluted barrel. It has a 3-18x42 Leupold VX6 on it.

I've been really impressed with a friends Valquartsen 17 WSM, out to 200-250 meters it is unreal.

I'm not a fan of the 22-250 or 220 Swift, just not enough umpf for wolves and to much for ground rats and such.
