Both long-range shots I've attempted on coyotes this season were 1st shot kills, one at 490 and the other at 350 in low wind conditions. Both were quick shots, lasered, referenced reticle hold on a sticker on my Butler Creek scope cap cover, in the 3-9X Burris, reacquire and shoot. 69 TMK did the trick, and once the trajectory is matched to the reticle it's as quickly referenced as just about any other system out there--IMO important for such a mobile target like predators, especially when hunting by myself with no spotter. Had one connection beyond 700 which I should never have tried. Hit but wounded only and the dog got away. 223 is good to about 600ish on coyotes and that's about it...IMO.
