I used either RELODER-7 OR IMR-4198 in my 30-06..

The velocity was slower,around 2850 to 3100..I found
the little bullets to be more accurate at this velocity..
I suppose you can use the same powder in your 308..
Not sure without looking,so you better check it out..

Never played with this bullet much so can't tell you
alot..Good luck..
