I shoot Sierra 60gr HPs at 3600fps out of my 243, and I don't have any exit wounds unless you hit shoulder blades, and then its not even a 100% guarantee of an exit wound.

I shot the 70gr Blitz Kings for a while and I wasn't impressed with them too much, as they wrecked everything I shot with them.

Hornady 75gr HPs do a good job as well, and are fur friendly.
