Wow this is strange. When using in the drill I start and for some reason I can not tell when it is not cutting anymore. I have no feel for this yet. It appears when I do this the corners of the pockets are shiny and a small amount of brass shavings. [b]So it appears just the corners need uniforming on my brass now]/b]
Yup, you're learning! A properly set primer pocket uniforming tool will ONLY cut a primer pocket deep enough to allow a primer to be set to the bottom of that pocket, which will result in the top surface of the cup to be .003-.005 BELOW flush. Cutting it deeper than that could result in miss fires.(Firing pin can't reach the primer).
