i've tried the barnes triple shock in my 300, it didnt like it, which led me to the bergers. I may try some hornady interlocks. had good luck with them in my 243. is a sheeps hide similar to a deer or antelope? I was shooting a 168 berger through my 300 and have never a large exit wound in any of them. The only reason i went to the 185 is i got a Huskamaw scope and get more yards out of the turret.
