Favorite powders for 120 PT in 25-06?

I accepted a project to reload some 120 Partitions in a M70 25-06. What are some of your favorite powders for the heavy bullets in 25-06?

Rl22 used to be one of my favorites, RL25 would work, as would 7828, 4831, Retumbo, H1000 or RL26/23. I’ve tried them all at one time or another. I like slow stuff in the 25-06 myself especially with 120’s.

What do you have available to you Dan?

IMR4350 is the powder I use in my brothers 25-06 with 117 and 120gr bullets.

I use IMR4350 with 115gr Partitions in my #1V.

Scotty,
I am being given IMR 4831 to work with. I DO NOT plan to use irreplaceable powders from my personal stash (i.e. Re-23, Re-26, Re-16). Since this is a time sensitive project (finish before I leave for Montana) I will be limited to what is currently available at the LGS - probably some of the IMR and Ramshot powders.

I don't know what primers I will be given to work with either. I also have to find out if speed or accuracy is more important to rifle's owner. I was told that 1-1/2 MOA would be acceptable.

I will find some of this out tomorrow when I pick up the rifle.
