I picked up a rcbs flash hole deburring tool and a large primer pocket uniformer. The deburring tool works nice. Its the primer pocket uniformer thats troubling me. I am working with once fired PMC brass, usually use winchester but got a bunch from a friend so. I used the tool on about 60 pieces, and It just bareley cut around the on the bottom of the pocket hole on 4 of 5 pieces. Is this what it is suppose to do? i thought that factory brass would be further of the spec and it would remove more brass?? I see that it is adjustable it has a set screw on it does it need to be adjusted? Thanks

The best way to test the results is to seat a primer. If the primer is raised above the level of the brass, then the uniformer isn't cutting deep enough. If the primer is seated properly, then the uniformer is doing its job correctly.

Sounds like your primer pocket uniformer needs to go in the drawer with the other gizzies you've bought but didn't really need. I've got a drawer full of 'em.

YOu don't want them cutting too deep either. I've used the rcbs quite a bit over the years and on some brass it does what you describe....perhaps better to say it uniforms the carbon.....and sometimes it takes a pretty good bite. Once I had some virgin win brass that had shallow pockets and it was a bit of work getting them in shape with the uniformer. That was one time I has happy it didn't dig deeper. Also....as you fire the brass with warm loads and get up to your 4th and 5th loading you will take more brass too.
It is the way it is....if the primers set deep enough its set correctly.

DON'T TOUCH THAT SCREW except to tighten it. It's the weakness of the tool. Probably done so that RCBS wouldn't need to produce an additional tool to cover large pistol primer pockets. It can be self-adjusting.

After you have some experience with the tool you'll understand why they call it "uniforming." The primer pockets change continually.

He is right. I mistakenly did and it took me about 20 cases (and about 4 hours) to get it set back to where it was supposed to be. It comes set at SAAMI specs from the factory and some brand casses are deeper than others.

Really believe in this tool and use it on all my brass. You gotta have some sort of an electric tool to use it otherwise it will take you forever. I got the RCBS prep center and love it.

About PMC, I just had the same experience that you did. Win brass (what I usually use) cuts quite a bit, but the PMC not much and much more on once side than the other. Also, I noticed that the pockets on PMC are bigger around (primers fit much more loosly) I couldn't even use Winchester primers in them since they are a little smaller. I came to the conclusion that PMC is cheap ammo for a reason. The brass will be good enough for bulk ammo, but I will stick to at least winchester for my accurate loads.

I have the Lyman primer pocket uniformer tool. like using the primer pocket uniformer tool to clean out the post firing residue.
It works much better than the RCBS wire brush tool the wire brush really scratched up the bottom of the primer pockets.
