To be honest I tried and tied to get the 120's up to breaking 3000 fps, it just never happened out of my 24" barrel. What I did find however was that with RL-22, lit with Win-WLR primers in both Rem and Win cases, I could get 3150fps with the 115gr Partition along with 1/2" groups at 200yds, so I settled for that and was happy.
If I had those powders I would at least give the 25 a try, as well as the 4831. The others might be a bit slow for it. I never tried the 25 in mine due to it not being out when I was working up loads.

I never got the 120's over mid 2800fps no matter what powder or what seating depth I tried. Not to say that wasn't good enough as it was an awesome accurate load using the 120gr Speer or Hornady. Just that I was looking for speed with that accuracy and it simple wasn't there. The 115's gave me the best of both worlds and also held up on up close shots where the others failed miserably.
With the same load the 110gr Accubond will run right at 3200 and also gets the same size or slightly smaller groups.
Now in my AI version the 120's rule, but your not asking about them.
Have all above powders RT. With H4831 which primers 210's??????Work up toward 52 grs H4831 with the 120's and you should find what your are looking for. If you can get some IMR or AA 4350 give 49 grs with CCI 250 primers a try. It really shoots lights out with the 120 grand slam Speer in my 25-06.
