I'm having problems getting OAL to be consistent when loading Hornady 150 gr. SST's. I'm using Lee dies in an RCBS PRO 2000. Get it set for 3.210", then it'll run 3.30" Adjust down and now they're too short! If I slam it into the seating die a second time at the original setting, then they're good. This ain't right! Suggestions?
