Are you going to be handloading for this or factory ammo?
If you are going to use handloads the factory settings are kind of a waist of time. After many many rounds of bullet and powder combos you could still be pulling your hair out messing with the BOSS. The easiest way for me was to find a bullet and powder combo that gave me the velocities I was looking for and then stick with that combo. Then start adjusting the BOSS untill you find the sweet spot.
