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.
