Okay, now - - One last time
The general consensus is that the .22 rimfire cartridge is NOT a sporting OR humane choice for shooting a coyote at 50 yards. I don't know most of the posters here personally, but at least a couple are known to me as very experienced hunters. Their advice is not to try it.
Even if you could make a carnial cavity head shot, there is too little energy remaining to ensure penetration into the sloping surfaces of the skull at that range. And, please remember, just any "head shot" is not a rapidly killing shot. There's plenty of energy there to break a jaw, though. Do you want to watch an animal, ANY animal, dash into the brush with a dangling, bloody, mandible, knowing that if it doesn't bleed out in the next few minutes, you've just condemned it to a lingering, painful, demise by starvation or infection?
You want to get into the camo gear and varmint calling, fine. You can probably get some 10 or 15 yard shots. I submit that your 16-ga shotgun with some #2 or BB shot might do an even better job at that range. I'd use lead shot for bettter energy and penetration.
A .22 LR will indeed KILL a lot of animals. But it frequently won't stop the larger ones quickly. Now, if my family was hungry, I bet I could provide a lot of meat from deer, cattle, horses . . . . In a survival situation, I might ignore not only humane considerations, but the law as well. (And, I don't pretend to know the Vermont law pertaining to coyotes.) But in a sporting situation, I will be a responsible sportsman. We owe it to the animals, even varmints, to provide a quick, clean demise.
Has this thread pretty well run its course?
