RE: the 17hmr and yotes?
Too small.
I've used it on prairie dogs and at much beyond 75 yds, they sometimes make it back to their holes.
It is accurate, just not enough power. Or maybe the velocity has dropped off and the bullet isn't expanding as rapidly as before. I haven't taken the time to look for exit holes on the longer range ones. Close range, it is farely obvious that the bullet is doing it's job.
