Has anyone tried a reduced (managed recoil)load in the 308? I have a Knight KP1 single shot in the 308 and I wanted to try a reduced load for my daughter. I want to shoot a 125 grain nosler ballistic tip.

Also, has anyone have a good load (not reduced) on the 308 with 125 grain nosler ballistic tips?

I have tried 50 grains of varget and get decent groups but I think it could be better.
