I'm in the process of building a 6BR with an 8 twist (just in case I decide to go heavier) to shoot 70 grainers as a live varmint rig. If anyone has played with this combination and can give a powder recommendation of what to start with, I'd appreciate it.

Right now the powders I have to choose from are:
RE-7
IMR3031
N133
H335
IMR8208XBR
H4895
RE15
Varget

Opinions on what to start with please.

Neither are on your list but I've had great results with h322 and n135, with light bullets, up to 74 grains, in a 6br.
 
again not on the list but very good and very popular is h322
