I’m currently working on 2 loads with the 166hh in a 300wsm. My goal is to get to 3200fps. Staball shoots well but seems to be hitting pressure too soon. RL17 is giving me great results and takes up much less room in the case. I am limited by saami mag length as well.

I agree with the last paragraph above. I would consider starting out with the hammer Hunters to build confidence. They fall more in line with conventional loading data and are very forgiving.
There is a lot of info there. But to clarify the question, why do you think that the loads will be too hot?
FWIW…My experience with 2 rifles with HHs and 1 with AHs is that is should take less than 20 bullets to find your load.
