FC, Don't know if you will be using fac. ammo or not, but either way, all of the Hawkeyes I have and the two I've given to my BIL and nephew all love the Hornaday Interlocks. 150gr. in the .308 and 30-06 and 139gr. in the 7MM08s. They worked so well that I actually have not bothered to try anything else.
