BSA, I'm not much of a believer in the idea of "best", but I doubt it'd be hard to beat a good 160 grainer.
I helped a friend pull a 160 HotCore out of the offside of a bull he shot w/ his 7mm RM... bullet looked like it came from a Speer catalog. Picture perfect.
Speer, Sierra, Nosler... they all make em.
That's what I was thinking Mac.... I didn't think you were a 7mm shooter but you did help me with finding a good load for my 300wsm. Thanks again for that. By the way, your new 30-06 is a shooter and that bull was a beauty!!!! I'll be out and about trying to find mine tomorrow.....
