8208 XBR or Reloder 15 in 6BR?

[varminater]

I was wondering of those who are are shooting the heavier bullets (105-108 gr) in 6BR, and have used both of these powders, which one you like better and why. I had 2 questions in particular I would like to have answered:

1) Which powder is the most temperature sensitive? If so, how much more?

2) What velocities will each powder give with your maximum load, using the same bullet?

Any other comments appreciated. Thanks, Bill

even though i haven't tried 8208 in my 6BR, and have no plans for that matter, i can tell you that 8208 will be, or should be more tolerant of temp changes. 8208 is a single base powder which lacks nitro, unlike alliant re-15 which is a double base powder. but, re-15 should yield higher velocity at lower pressure than 8208 because it is a slower burning powder (according to burn rate charts). i think that 8208 is better suited to light to midrange weight bullets.

Cole, Thanks for the input. It sounds like the reloder 15 is the clear choice for my stated application. Bill
