My brother has killed about half a dozen yotes with a these bullets out of his savage predator in .223. All have been one shot kills, ranging from 60 yds to 280. I did watch one dog run about 50 yds on a lung shot from about 275 yds. None of the hits have left an exit wound, and all but the one were DRT. I've also seen him shoot 1/2 gallon milk jugs with these loadings at a range finder measured 425yds. A very good bullet for most applications in the 223.
