So I would think anything over 1800 with the 120 should work
I use 120 @1950 in a 7tcu
One of the considerations when using light bullets, e.g. 100 gr., 110 gr. and such for Ram; is that you have to drive them at almost 2500 fps muzzle velocity to maintain a decent TM at 200m. When you do this, you damage the 50m Chickens and most Match Directors will pull you from the line if you start to damage their targets; unless you use a lower velocity load for C,P & T (which just complicates reloading and shooting for some of us). Remember, TM is only a consideration for Rams !!!!

When I shot 6BR in my UL XP, I ran 107's at 2400 fps, with no target damage. At least I never heard of any! :)
