Tumbler Media Sticking In Primer Pocket

After the final cleaning and polishing of my brass about half to two-thirds of the cases need to have bits of cleaning media removed from the primer pocket. Perhaps this is just a fact of life. But if anyone knows of a way to prevent build up of media in the primer pocket please clue me in. Thanks.

Easy, do remove the spent primer, toss them in the tumbler.

That's just what it does when you tumble brass that has been deprimed. I made a tool from some stiff piano wire and a file handle just for pushing the kernals out of the flash holes.

I've never found a way to keep the kernals from sticking in the flash holes and have just learned to live with it. I consider inpecting the flash holes another part of the loading process for brass that's been tumbled after depriming.

Hope this helps.

I tumble before sizeing and they come out with the primer.

I also tumble everything before sizing, but I also tumble again to remove case lube on those calibers that must be lubed prior to sizing. That's when the media gets in the flash holes, which is probably what he's talking about.

Hope this helps.

I just stand them all in a 50 round loading block and punch them out from the back with a sharp scribe while I am inspecting the heads for other defects.

On the otherhand, I doubt a single bit of walnut media left in the flash hole would make the slightest bit of differance when the primer goes off behind it!

It is going to come out and be consumed before it even gets out of the case into the bore.

Couldn't prove it though, because I've never been able to find one to look at. :D

Try some of this stuff. It's cheap very fine, and does not stick in the primer flash hole. It is untreated. I used 10 capfulls of Nu-Finish and it works great.

please clue me in

I tumble my brass after decapping only. I ignore the media that may be stuck in the flash hole. The decapping pin pushes it out when I resize.

I tumble first then de prime. Also i use lyman treated media (ONLY). Yes i know you can use any tumbelin media. Go to a petstore add new finish.


NOPE NEVER AGAIN.

I was always using lyman media. Then i gave it a shot and added a cap full of new finish. Well i noticed no difference so i added another capfull.

Ya for almost 2 months afterwards i would have to Wipe down every friggen case. As the nu finish would leave a white powdery like film on all the cases. So now i jus use lyman treated media. Thats it thats all i use and all im going to use.

Tip though add either dryer sheets or small pieces of paper towels.

I don't know what equipment your loading on, but when I clean the lube off rifle cases after sizing them and have corncob stuck in the flash holes, I just use a universal decapper in the first position on a progressive press.

YMMV

1. tumble with spent primer in the cases
2. lube if needed when resizing/decapping, same step for me.
3. Load primers while checking flash holes
4. Load powder
5. Load projectile
4. Tumble loaded rounds to remove any case lube and/or fingerprints.

Should be the least amount of plugged flash hole risk this way.

I hear ya. I deprime before tumbling, and now punching the walnut media out of the primer hole is just part of my brass prep routine. Fortunately, I reload in small amounts, so it's no biggie. FWIW, I deprime and full size (handgun; neck size rifle), then soak in a vinegar solution overnight, rinse and tumble. Primer pockets come out clean as a whistle, but often plugged.
