My experience is the same as Brad's. While have gotten pretty good accuracy with some Interbonds, they often refuse to shoot as well as Interlocks in the same weight/diameter--and at .308 velocities sincerely doubt you will find any difference in terminal performance either. In fact doubt you'd see much difference there even with today's 165 SST's, which expand and penetrate at least as well as Interlocks.
The .308 will shoot well with a BUNCH of powders. I tend to use Varget because of living and doing most of my hunting in Montana, due to both its temperature resistance and fine accuracy. It is VERY rare to find a .308 that won't shoot 165 grain bullets with around 46 grains.
