In my oppenion the Rock River Coyote is the best gun on the market. All of the coyotes I have ever shot have been running and I have only killed 2 with 1 shot kills. The last 1 I killed I shot at 6 times, and hit it 5 time, they are hard to kill. I do use eather a 224 TTH or a 6-284 and soon to have a 6-300 WSM for long range, well any time I`m going to be shooting over 300 yrds. I use a drop chart and a range finder and dial up the hold over so that I can keep the cross hairs on the target. These set up are not the best for under 300 yrds.
