RE: NEED HELP, QUICK!!!
In 30 years of coyote hunting, I don't think I've ever seen a coyote standing still at 600 yards "at least" long enough to set up a shot on one. As well, at that range they present a target small enoughthatsome kind of rest or bipod is almost a requirement.
I've hunted coyoteswith a variety of calibers, but have found that the .223 is theMOST effective inMOST shooting situations.
Ispent a couple days at the range last week shooting E-silhouettes (iron maidens)at 600 yards with a .308. In spite of it's apparent lack ofvelocity and heavier bullets, it EASILY gets out that far, butI don'tintend tobe shooting coyotes that far out - ever.
