I"ve used them out of my moms .243 at 4100fps on a few coyotes. The ones I shot were all bang flops. They did not exit, but the entry holes were pretty nasty. Its kinda toss up because IMO, they can be a good fur bullet because there going so fast, there a light bullet, and they dont penetrate to well. So with that being said, yes they can be a good fur bullet, but look out for entry holes as sometimes they will be just as big as an exit. I would try to stay away from the shoulder if at all possible. Try for behind the shoulder and you'll be good to go!!!
