Which powder is most likely to give me the best combo of velocity and accuracy? What is a reasonable velocity expectation with the 140-142? 3050ish fps?
Sam, I suggest you read this: 6.5-284 Cartridge Guide
Looks like the bulk of the benchers use either H4350 or H4831SC.
That said, don't forget that Vihtavuori N160 and N165 have been top choices for this caliber for many shooters.
I was told the guys at Best of the West have been using up to 59.0 grains of Retumbo, but they may go back to H1000. These powders are used with the 140 Berger VLD.
I am curious as to how well H414 and Ramshot magnum would work.
