I built my 6.8 SPC to give me more energy from an AR-15 platform on large coyotes. The 6.8 is working perfectly on called coyotes, but I don't care for it as a spot and stalk open country rifle. If I'm going to hunt around open fields I use a bolt action in .22-250 or .243 Winchester. in open country I can go to kneeling and make a 250 yard shot, when a bedded coyote stand up, with these bolt action rifles. I'm not comfortable trying it with my 6.8 and won't attempt it. When I'm calling from thickets it's my 16" 6.8 SPC, which I think has no rival as a quick handling easy swinging brush gun. No different than when hunting with any other AR. I don't use them for long range open country hunting. Each rifle has its strong points. Use the right tool for the job.
