Bear2000,
I use one each and every time I reload for rifle. If nothing else, it cleans the fouling off of the bottom of the pocket.

I don't think you will wear out the brass. The primer pocket uniformer only goes so deep. The whole idea to make the uniform them and go no further.

At the most once and certainly not with premium brass. Getting compulsive about cleaning primer pockets is a waste of time.
The purpose is to have all pockets at a consistant even depth. Grit in the pockets defeats uniforming and should be removed if you think the pockets needed reworking in the 1st place. Even with "Premium" brass.
I use a uniformer once, then clean with a RCBS casemaster. I don`t like cleaning with my Sinclair uniformer due to fact I worry the carbon grit might be hard on the tools edge. I like nice sharp cutters and the RCBS primer brushes work very well on the ash IMO.

P-P Uniforming
Every time a case is fired the brass flows, most will flow to the neck but after a while you will see it flow into the primer pocket. We started making uniformers with tool steel cutters, and the carbon did make us change it to carbide. if you clean with a carbide uniformer you take care of any flowing brass. If a carbide ever dulls send it back. they should back it forever

Well, IF brass were flowing into the primer pocket, they should get tighter and that just doesn't happen. Think a bit on why brass flows and I think you'll see that it's not going to flow into the primer pocket.
And for you folks who think you primer pocket cleaning/uniforming does any good, do your own double blinded study on it and I believe you will not be able to see any difference at all on paper between rounds shot with spiffy primer pockets or those that are dirty or as they come from the factory. The only possible exception might be those competent enough and who are shooting a good enough gun to consistently shoot groups of 0.25 inches or less at 100 yards.
But, go ahead and waste your time if you like. After all, it's your time.

Its the "web" of the case that worps into the pocket. Not the primer pocket "walls". I don't use it for the fact that I want clean primer pockets. And yes I know it doesn't do much good for paper. I do it for the safety of not having high primers. The last time I measured of what I removed was .0010" to .0015."

Yep. Even after having removed some brass at the bottom of the primer pocket, after shooting a heavy load, you will likely remove some more brass at the bottom of the pocket the next time you reload.

I use it on expensive new '06 brass that I'm loading my best hunting/target loads in. you'd be surprised at the 'flash' I've got out of there with it.
just regular 'blasting ammo I don't bother.

Well, I have had some Federal 308 Winchester cases since about 1984 that have been reloaded so many times I've lost track of it and my failure to keep uniforming the primer pockets has yet to give me a high primer.
In a gun club I belonged to quite a while ago we had benchrest matches. One of the regular competitors, who was much better than I, used the same cases in the match. He had 5 cases and between strings of shooting would knock out the primers and reload them right there. The bullets were seated with his fingers and he definitely didn't uniform the primer pockets every time he shot. If this guy who did consistently shoot 5 shot 100 yard groups in the .25 inch range didn't think continuous fiddling with primer pockets would help him, I doubt I could improve much on his procedure.
But, you guys do what you like.
