Dunc2, I've used Nosler SBBT in my .270 exclusively for about 15 years now. I tried Partitions but they didn't group near as well as the SBs. And for deer and black bear, they are devastating. The only thing that comes close to shooting as well in my 270 is the Speer 130 gr SPBT.
I've been trying to find a good load for my 7-08 also. I would appreciate it if you would let me know how the solid bases shoot for you. So far in my 7-08 I tries Rem core-lokts 150 gr. and Hornady 139 gr. The 150s show some promise. If the SBBTs work for you, I may give them a try.
Its funny how each rifle likes a particular load, but that's what makes reloading fun.
I've been loading now for almost 40 years and I'm getting pretty good at finding a "starting" load then fine tuning it. It seems over the years that for my rifles I can probably get by with only 2 powders. IMR4350 and IMR4064,
