[ame]https://youtu.be/NsMzrg-9Q_snteresting[/ame] thread, having killed hundreds of coyotes with numerous 50gr bullets, ouf of .223, and 22-250's and 243s (Vmaxs in both the 250/243) I would have to say inside 300yds they kill well, however alot of how well they kill is where you hit them, and what area you live in. A little 22lb southern dog is ALOT different, than a 45lb northern dog, of course generally speaking if you double the bullet weight (similar BC) you should half the wind drift, vel being the same. So a 50gr bullet going 3000fps should have roughly double the wind drift as a 100gr bullet going the same velocity. Of course if you up the velocity on the lighter bullet than the TOF is shorter and that also can help the lighter bullet, I am wondering how practical a 53 gr bullet really is at 400/500 yds knowing you now have a couple of feet of hold off to hit the coyote? We can certainly do it via a Mildot reticule, but is holding TWO mil dots or more, when the coyote is standing so instead of aiming at his tail, you are actually aiming two feet out infront of his chest something you want to mess with everytime you want to shoot over 400yds in a light breeze?
I have a 12"/16" steel plate across the cove at my camp its 552yds to the plate, lots of guys can hit it when its flat calm on the lake, very few can hit it in a 10kt crosswind with 50gr bullets! Lots can still hit it with 100gr bullets
Something to think about....
I personaly think they can be very tough to kill sometimes, here is the link to a video showing one hit thru the side of the chest , down thru him and exiting out thru the back of his groin area, 87gr Vmax at 3100fps, basically end for ending him, see how far he goes!
