Missing, bad hits....it is called, "Hunting"....
Coyotes coming into a call often do not stop, you can yell at them, whistle, bark....they just keep hard charging! You leade them, follow though with your swing, and you hit them all over the body... Hits behind the diaphragm on coyotes, usually means a lost coyote with sub calibers.
Hits behind the diaphragm with a 243 and 22/250 AI means a very dead coyote. I do not save hides, so I am a, "cutt'em in half kind of guy" with the caliber I choose. I have killed plenty of coyotes with 22 Mag Win HP, 22 K Hornet, 17 Mach 4, and 17 Rem.
Out West, we slaughtered the chucks in Idaho and Utah. I liked the 222 with a 50g Ballistic tip and 50g Sierra blitz as a minimal cartridge after seeing more than a few crawl off...I hate crawlers. Chucks can be tough to anchor solid on quartering angles, and WIND is always an issue.
We had a ranch we shot that was a feed lot for cattle. The chucks would move in out of the dessert/lava rock and looked like terminates moving in on the cattle's feed bins, which were 2x12' nailed in a V form with legs on the bottom....just the right height for a chuck to crawl into. The trick was to flip the chuck out of the feed bin and not bloody up the feed for the cattle. Unbelievable that the rancher told us to not worry about hitting a cow, just come and get him if we did hit one....we never did.
My favorite Chuck rifle is a 6 Rem AI with 70g Blitz Kings at 4100-4150(26", 14T, .020 FB). I like to see the chucks getting T'd off like a football going for a Field Goal! Flying...not crawling...
Topic is shot placement, so I place my shot to get the most Air Time.
