Sorry had to pick on ya. Comparing the shock, awe, and damage from a .22LR to a .223 on is kind of silly. If you shot a yote close range, for instance the 75 yards the post orignally indicated on trying, a .223 and a 22-250 would rip through and either be stopped after breaking bone, or passing through ultimately. A .22LR in the chest at 75 yards is not even the same as a high powered .22 caliber, not a stinger or the like, but .223 and higher. And shooting a yote with a .22 LR in the chest instead of a well aim brain shot is also silly, borderlined irresponsible as well. My advice on the matter, if you cannot gurantee an accurate brain shot on a coyote with a .22LR, don't shoot it at all. Upgrade your gun for a more powerful caliber so you can take the yote or predator in the chest vitals.

thx for the info guys, I'm also thinking of investing in a .17 hmr can someone please clarify the difference between that and the .17 mach 2 and which is better for yotes and a good gun in either

17 HMR is a 22 magnum case necked down to .172' diameter and the 17M2 is a 22 long fifle case necked downt to 172' . with a 17 grain bullet the 17 M2 give about 2100 fps from a rifle and the 17 HMR delivers about 2600 fps from a rifle also. Im not sure about the size of the coyotes in your area but the 17 HMR is completly capable of taking a coyote under 100 yards. Im talking from personal experience here too. i would be kinda shy about using the 17 M2 on coyote though. as for using a 22LR on a coyote, if thats the gun you can shoot, use it. a chest shot will work but should be avoided at almost any cost as the animal would run a great distance. Just make sure that you use a good scope that is zeroed correctly and dont shoot beyond the distance that your gun can keep 5 shots under an inch and a half. follow these directions and you should be fine.

you really shouldnnt have to do any thing to an AR-15 except mount a scope for coyote hunting.

Rick Pallet from Vermintators, the designer of Thumper and Tweedy calls uses a 10/22 mag for coyote and bobcat, the 22 mag is a 40 grain bullet and the 22lrviper is 36 grains, the golden bullet is 40 grains. The 22 mag is 1900 fpsmax for a 40 grain, the 22lr for 36 grain is 1900 fps and the 40 grain is 1500. Do you claim 4 grains of bullet makes that much difference? Now as for the shooting coyote with 22lr, yes 223 and 22-250 are faster, bullets are better, but I beleive the question is will the 22lr work at 75 yards and the answer in my opinion is yes, but your goal should be to call it closer. Is the 223 and up abetter tool, yes, but at 50-75 yards you won't notice the difference. I beleive shooting any animal in the head is irresponsiable, the reason is the contours of the head sometimesdeflect the bullet up the scalp, some bullets will explode rather than penetrate, other just flintch and hit the snout. Whether a 3 inch exit wound from 223 or 22-250or a 1 inch exit wound from a 22lrthe coyote is dead just as fast. And the 22lr yellow jacket is 33 grains and 1700 fpsandactually explodes which is why I recomended it. But I do respect your opinions.

thx again guys for all the info... I'll let you know how i do this weekend

I would never EVER use a .22 LR under even 10 yards with a coyote[:'(][>:][&o]. The bullet is way too small, it doesn't have enough power (or even close) and you will most likely need a couple of follow up shots.I don't know what your thinking about shooting a coyote out to 75 yards with a practical BB/pellet gun.[&o] An RWS would even be better than a .22 LR(considering certain factors)! A .204, .22 mag, .223, and .243 are the obvious choices in this case.I CAN'T EVEN KILL A GROUNDHOG OR RABBIT WITH A .22 LR at 50 yards[&:][:'(][>:][&o]!!! My friend put 7 shots into a fat groundhog at a paced off37 yards until it died[>:]. And a rabbit has REAALLY thin skin and I still have yet to kill one at even 35 yards with a .22 LR[:'(].

Take em' in the head deerslayer !

A 22 magnum or a 17 hmr for shots under 100 yards is my feelings on this one ive experinced 1 shot kills on yotes with a 17 HMR. a 22 lr ummm well..... Ive been there shot a yote at about 30 yards with a cci stinger hit him square in the lungs good pink foamy blood trail when I caught up with it I put another right in the boiler room again he run another 50 yards when i caught up with it the second time I stuck one right in the cranium then a second for good measure. not my idea of humane kill having to put 4 shots in a yote to dispatch it. but then some guys might get a kick out of that, but thats not for me. for awhile i used my 17 hmr but after a few kills I decided even it wasnt enough especially if you hit a rib you might need to stick a second round in it. Ive since went back to my feeling of nothing smaller then 17 cal centerfires for yotes.

if money is the issue you are lookin to use rimfire guns, you should look into a stevens model 200 they run about 275 bucks not a whole lot more then a rimfire rifle but they make them in all the best varmint calibers the .223, 22-250, and 243 any of those 3 you wont have to second guess wether you have enough gun or not.

Howler and HighDesertWolf are right. putting 4 shots into a coyote isn't the kind of gun you need. and also you DO need shots under 75 yards. I wouldn't even try a .22 LR if it doesn't even kill a groundhog with 5 shots.

Here in WV we can only use a rimfire for yotes at night.
Would the 22 mag be the best for 75 yards or less?
