Was making a run of 1,000 45 acp yesterday and about 150 rds in this happened . The press started to feel wrong in the upstroke then It jammed up , so work stopped, pulled all the rounds off the press and in station one I could see spent primers jammed under the shell plate. I also noticed that allot of the primers were split which I think caused the problem . Took about 15 minutes to clean out the spent primer chute. Anyone else have that problem with a Dillon SDB.
