While I don't shoot it overly hot, only about 3870 fps, it is highly accurate and hammers the critters with no fur damage if I hit them center mass.
I have yet to shoot a coyote with them, but I use a healthy dose of Varget in my 1:14" twist CZ 550 Varmint Kevlar .22-250.
They shoot amazing out of this rifle, but I haven't shot a coyote with it. Every time I take the rifle, which is heavy, my son ends up shooting the coyote. Not a problem, it's good luck I guess.
WyoBull got me on these bullets because of all the success he has with them in his swift. I may even try them out of my .22-250 Ackley.
