I picked up some 155 grain cast lead round nose bullets. If I seat them to 1.135 , there is quite a bit of the shoulder still above the case. My Lyman manual lists a OAL for a cast 150 grain ( # 40164 ) as 1.090 . If I go with that the shoulder is right at the case. I just am always worried about overpressure on the 40 if i seat to deep. Any suggestions? FYI I am using 5.5 Grains Unique , shooting a Sigma.
