Does Primer Pocket Uniforming Weaken Brass?

I have Sinclair's primer pocket uniformer and after uniforming some 556 LC cases I noticed quite a bit of material accumulating in my pile that was removed. The tool is not adjustable so I can't really goof up with it. I load to 556 pressures.. should I be worried about weakening the brass? I'm only doing this to prevent slam fires, not for accuracy.

No.

Worry about high blood pressure.

I use the Sinclair PP uniformers and they're safe at what they do.

+1 on the concentricity; uniforming the DEPTH of primerpockets is no concern for brass strength, but if slighltly WIDENED, the brass will last you lesser number of reloads s the pocket will sooner get loose to hold and seal the primer.
