Does Primer Pocket Uniforming Weaken Brass?

[dan45hk]

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.

No they dont remove much it may look like alot but weigh it. Its like flakes of foil look big but they are ultra thin.

+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.

You could probably prove it does in a laboratory.

I also use a Sinclair PP uniformer on all of my new 300 win mag brass. Never had an issue.
