The .270Win, along with the newer .270Weatherby and .270WSM is a wonderful, long range shooter, capable of taking elk, moose, deer and on done the game range of animals. The .270Win will kill any coyote at long range. With FMJ bullets, you should not see much of an exit wound. The problem with .270Win for coyote, is the report. That rifle has a real booming sound when it goes off. Sometimes two coyote are working in on your call and when you shoot one with the .270Win the report is so loud that the second coyote always skeedaddles off. Sometimes, when you use a .223Rem or .222Rem the report is mostly swallowed up by wind and will not spook the second coyote.
