RE: boss system reloading
songdog, I have a 30-06 Browning with the Boss. In finding loads for it, I check several sources for data. I tend to look for loads that are relative fast, use enough powder to fill the case. I try to find loads that are consistant in speed. Then start loading up plenty of ammo. Then at the range I start with the suggested Boss sitting, shoot 5 shots off the bench and adjust the Boss about 1/4 turn. Then repeat until i find the best setting.
Good Luck & Good Hunting
