Yes, I do. In keeping thing simple I use the same loading of H322 at 24.5 grains, cci 400 small rifle primers and 50 grain SXSP's that I worked up for my Savage Md 11 in my AR. The only difference is that I use LC 02 brass so if I loose a few out of the semiauto action I have plenty to replace them with. They shoot very well out of the Shaw 1/9 twist 20"barrel. If I can hold the round forarm still enough MOA is easily obtainable. I haven't chronied them out of the AR but in the Savage they leave the 22" 1 in 9 barrel at 3253 FPS. A half MOA center to center has been printed using 5 shots a 100 yard a number of times with this combination. In testing if the SXSP's are pushed any faster then the jacket started to shred and many times the back stop wasn't even touched. The velocity acheived now is the highest I could use with out this problem. As long as the leg bones are missed the coyote will die and usually right there. Sometimes they will exit and other times they grenade completely in the chest cavity with spectacular internal damage. I started using them out of an old 222 and had such success that I stayed with them for the 223. Good bullet but if it weren't so populated in this area I think I would use a heavier, stiffer bullet. Even so not a coyote I've hit with them has ever been lost to date.
