I am considering an AR in one of the 6mm wildcats. (AR15 platform). Mostly for coyote hunting and the occaional deer / antelope. I am looking at the 6mm woa and considering Carey Custom Rifles to build an upper as one possiblility. The 6.5 Grendel and 6.8SPC are not really what I am thinking. Appreciate the experience/feedback you may have.
