I saw some of those (QUITE a while back) at a local store (which also sells some guns and ammunition)...
Personally, I don't know what's wrong with the .308 (without the Sabot) for Coyotes. That's what I've been using, and it works GREAT!
My friend (Chuck) has worked up a load of Hornady 155 gr. AMAX (which is a match bullet). It's chronographed at 2900 fps, and is VERY accurate. Any decent hit from a .308 will be fatal. Chuck has been amazed to see that the Hornady AMAX's leave a SMALLER (usually) exit would than his .243
On more than one occasion (from the front) the bullet has not exited (no fur damage). In fact the ONLY time we've had significant fur damage (still sewed up just fine, just took longer) was when I hit 'em too high...
I know lots of folks want to use a 22-250 or .223 or .243 or whatever... I use the 155 grain AMAX for Coyotes, and the 150 grain Interlock for larger game. The point of impact (at least for MY rifle) is almost identical.
Best of Luck with whichever one you choose.
Hunt Safe!
