Cleaning primer pockets

21 posts in this topic

How about skipping the brush and just using a primer pocket uniformer? If you're going to use the uniformer anyways, it does a good job of scraping out the crud.

I haven't used the primer pocket brushes in several years. The problem is you can remove brass and damage while cleaning the primer pocket, making correct depth seating a problem. I use the Sinclair 8000 Series Uniformers in small and large primer sizes. I also use them in a drill or drill press to speed the process. Primer pocket uniforming is a case preparation task that should be performed each time you reload. The Sinclair Primer Pocket Uniformers are designed to cut the depth of primer pockets to the correct SAMMI specification and also to clean the carbon out of the primer pocket after each firing.UN-8001.jpg

Thanks, John. You've steered me in the right direction before so I am going to give it a try.

That makes excellent sense! Now why didn't I think of that!!

When I was shooting a lot of straight wall pistol ammo, I cleaned the cases with rice hulls in the cleaner. The sharp hard point of the rice hulls would clean the primer pockets pretty well. Don't try them with bottle neck cases though.A17Shooter

Because they get packed in the case and are a pain in the butt to remove. Right Gary ;)

Well my package was supposed to be here today but it never came. I guess I will have to wait until Monday for the new tools and to set the trigger on my Remington.

Get your cordless drill battery charged up so it will be ready when the uniformer arrives. :)

Is there a better (easier) way of cleaning primer pockets than to use one of these?
yes, go to http://www.championsbrand.com and purchase some Media Modifier C/PX or their new Ultra-60 anduse it in conjunction with their champion's grade media blends which is a combo of corn cob and walnut mediaUltra 60 will clean your brass including your primer pockets in less than an hour - you will think you just purchased new brass

Mine got here too. I'm going to test it out this weekend in a new tumbler that's been sitting around waiting to get tested. Remember that media already has the modifier in it. At least mine does. :lol::)

I've got some sized brass in the tumbler right now with the new media and the compound that Goguns recommended. It's got a half hour to go before the one hour is up.

The clock is ticking! tick tock, tick tock. :( Did you use the correct amount of modifier with the media? A pound of brass to a pound of media. :angry:

Nope. I only had about 30 or so of the 17 Remington cases that I hadn't already cleaned primer pockets on. 15 minutes to go.

Not a fair test. Bogus bogus... :( Clean doesn't necessarily mean shiny in a primer pocket. Maybe I better close and lock this post before the clock runs out. :angry:

I am actually pretty impressed at how much that brass was cleaned in an hour. With the condition that my brass was in when it went in the tumbler I was guessing it would have taken me 4-5 hours with my old media to have it looking good.

just got back from an IDPA match very interestingok, so I am biased (is t hat spelled right)I found with up to .223 size casesa pound of media to a pound of cases works greatthe more action the betternow a big tumbler such as dillon or a big lyman (mine just died)the mix will changeyou cant' clean 17 rems with a pound of media in one of those big tumblersi just cleaned 13 pounds of 9mm with 10 pounds of walnut/corn and ultra 60 in a dillon 2100ti did the job quicklybut with small tumbers like frankford the above ratio works very well17 rems will not create that niagra falls effectwhich is necessary to get the job done quicklyanother thing is, I assume that you clean the primer pockets each time your reloadbecause if you don't, that primer pocket is glazed with carbongoguns and out
