Im curious. Ive not had a turret press. Were you using it sort of like a progressive, put shell in, do every step without removing shell until done? I thought the idea of turrets was to save time changing dies, not so much to use them like a progressive? Do one individual step on every case, advance to next die, do that step to every case, etc. So used, it would be impossible to repeat the mistake, as you would be inspecting each case and primer each step.
The Lee hand priming tool became my favorite for most priming on single stage presses. Ive not had any high primers of any sort make it past the priming stage with the single stage/Lee hand prime tool method, or with single priming in a single stage RCBS press. Every one is visually and feel checked when using the Lee tool, or the single stage press. With the Dillon 550, Im maybe a bit overcautious, but if a primer doesn't feel like it seated correctly, I stop that step, pull the case and check it. I check all rounds loaded on the Dillon also before assuming they are all good and boxing them up. With being suspicious of odd feeling rounds, Ive kept it to zero real problems of rounds making it to a gun. The occasional cases with really tight primer pockets get culled. They aren't worth the time to mess with to get primers to seat below flush. Ive used batches of culled loads with extra tight primer pockets and shot them up and just left the brass or dumped them. Maybe my priorities are wrong, but I tend to run the Dillon about 300 rds/hr. Ive never just tried for top speed at the expense of being super careful all steps work to my satisfaction, like visually checking every charge also.
