You could try Hunter with the 120 gr BT.
QuickLoad shows max @ 51.3 gr for 2923 fps with 100.8% case fill, at 63,041 psi pressure in a 18 1/2" barrel.

I don’t have any of the RamShot powders on hand. I tried them over twenty years ago and none of them really worked well for me back then, and I never tried them again.

To give you an idea of the difference in velocity I compared the speed from the 18.5" .308 Win. Ruger M77 RSI vs the 22" barrel from a Winchester M70 Youth Ranger. in .308. The load duplicates the now long gone Speer Nitrex ammo with the 165 gr. Grand Slam. I used the 165 gr. Speer Hot Core bullet.
Ruger RSI: 2550 FPS
Win. M70 Youth Ranger: 2610 FPS.
