I used a 6 WOA AR-15 this past winter for predator hunting. Shot 29 coyotes with it and had to shoot 1 twice. The load used was a 65 grain V-Max with Benchmark powder yeilding 3425 fps in a 22 inch barrel. I also have a 243 WSSM, but the pinpoint accuracy is not there with it as it is with the 6 WOA.
Accurate rifle are interesting
