For one of the local Doctors, that is attached to one of the Mormon Boy Scout Troops, I dissected and loaded some Federal 30/06 ammo for him..

Checking the powder used by Federal, the charge weight and then chronographing it, then reloading the ammo with RL 15, I got the same MV and same POI on the target.

So at least with Federal's 150 grain 30/06 load, they are using RL 15... both are owned by ATK anyway, so it makes sense.
