I asked the same question a couple of months ago. Since then I've shot 3 coyotes with the 40gr V-Max. 1st one @ 165 yds, spun 3 times, no blood, just entrance hole in chest, broadside. 2nd one @ 200 yds, spun 3 times, ran 20 yds, no blood, just entrance hole in chest, broadside. 3rd one @ 294 yds, DRT, no blood, just entrance hole in front of chest, facing me straight on. I used 52 gr Sierra HPBT and Hornady 52 gr HPBT before and generally had 2 holes and blood out their mouths. This is out of .223 AR 15's with 20" and 24" barrels.
