Problem solved. Dropped H1000 powder charges down from 80.0 grains to 75.0 and 75.5 grains. Velocity went from 3150 FPS to 3000 FPS 162 grain SST. I guess the Remington brass was swelling too much. Primers and case heads looked fine at 80.0 grains and bolt lift was fine. Case was just getting stuck.
