I do this on the 1st reload of all brass.
I i need to do it anymore?

My case prep center,will not allow to take off more than needed,it has a stop on it.
 
After uniforming the 1st time then the uniformer is a perfect tool to remove hard primer residue. I use my uniformer to clean the primer pockets.

You are braver than I am. I would worry that the carbon may dull the cutting edge on the PP Uniformer and render it useless. My 2 cents worth.


To the OP. You only have to do it once.

A few years ago somebody gave a warning on a thread about taking away too much brass away from the primer pocket area and then getting loose primers on your brass much sooner than you would have if you hadn't uniformed the primer pocket.

I bought a RCBS Case Prep Center and started uniforming primer pockets on all of my brass with both small and large primer pockets.

As soon as I started seating primers in the brass with the large primer pockets I found out that my RCBS Large Rifle Primer Pocket Uniforming tool was a little too large in diameter.

My RCBS Large Rifle Primer Pocket Uniformer pretty much ruined all the brass that I used it on no matter what brand of brass it was.

I did fine reloading rifle brass for many years without uniforming primer pockets other than military brass so no more primer pocket uniforming for me.

This is what I do with the Sinclair uniformer in a drill.

There are several tools made just for removing carbon. RCBS makes one looks like a witches broom, I use one from Lyman that is a small checkered barrel with a cleaner for small pockets on one end and large on the other. One at a time by hand. I cut the pockets once then just clean them, but not with the cutter.
 
I also use the RCBS cutter to clean my primer pockets. I really don't keep track. I just clean when I notice they are building up residue.

Good post here. Hopefully some will listen. I think a lot of guys do more harm than good to their cases and don't know it.......
 
I've never uniformed a primer pocket and don't own the tools to do it. I brush my pockets with the case prep center to remove the primer residue and that is it. I've never blown a primer and have tight fitting pockets on my Lapua 243's after 6 firings and who knows how many on the Winchester 223's. Honestly, I never saw where any good could come from it for my uses. My thinking is less brass=weakness. The only thing I do other than brush pockets is swab them with alcohol to remove any dust from brushing and debur the flash holes to remove the punched out flap on anything that isn't Lapua when I first get them.
 
I am the same way. I uniform once, then use my RCBS brush to clean with afterwards. I fear that repeated uniforming will thin out the primer pocket resulting in premature case failure.

You won't remove enough brass to notice a weakness. The primer cup is the weakness in the primer pocket, not a uniformed primer pocket.

Try this: Do a shoot off. A load sequence with brass having uniformed pockets, and an identical set of loads with untouched pockets. Make it a blind test....have someone give you the ammunition. You won't see even the tiniest difference in accuracy.

I just figured the uniformer on it,and it only takes like 2 sec per piece so i do it one the 1st load.I figured it wouldnt hurt accuracy,lol
i do know it eighter helped or Varget powder is the best ive tried yet.I just found a load that shoots better than any ive tied.with brass i uniformed on my prep center.lol
 
i read somewhere...beleive it was a precision loading/shooting book.. and i'll try to quote as best as i recall...." if you do nothing more than just squeze your cases down and stuff them w/ componets at least uniform your primer pockets/flash holes"....
 
Flash holes are worth doing, primer pockets aren't, IMO.

When you uniform a primer pocket you may or may not end up with different thicknesses left in the webs of your cases. Some walls may end up thinner than others, unless all started off EXACTLY the same. Either way, I do not believe you will see a noticeable difference in accuracy....

Just because someone writes it, doesn't make it true. I think it's complete nonsense. I'd love to see it shown that uniforming primer pockets has even the minute-est effect on accuracy. Any change in accuracy is strictly in the mind. But hey, people believe what they want to believe.......whatever sounds good and somebody thinks it's worth doing should do it.
 
Betcha it makes more difference on poor brass than high end cases! But then, ya can't make a silk purse from a sow's ear either. IMHO spend the time on flash hole de-burring and skip the primer uniforming.
 
Why don't you swage them? That RCBS crimp remover doesn't remove any brass other than the fine "ring" that's been forced out over the primer.

I get real good primer pocket life after using that, and the seating pressure on the primers is very consistant.
 
Have 8000, 223 brass, Trued pockets and flash holes 1 time, have been shooting same brass for years and have never cleaned again and have not noticed a difference in accuarcy.
