Just finished prepping my brass and started to put in primers..Every once in awhile one would stick and not go in very far..So after 21 cases ( 3 primers not in properly) I decided to go over everything to see if I was forgetting something..Well I was..I forgot to check the brass for cleaning media prior to the primers.I'm using that Lyman pebble stuff that came witht the tumbler and it tends to get stuck in the primer pocket..I inspected all 100 remaining cases and found that 95% had some media in the pockets..NOW my question is this..Will the new primer push out the remaining media ( I'm assumung the 3 cases where the primer didn't seat had major blockage) or should I just de-prime the cases in question and start over..

What would happen if the primer seated properly but the flash hole was partialy or fully blocked?

It is highly unlikely that you will push the tumbler media out through the flash hole. More like you will simply compress it between the primer and the pocket.

If the primer seated properly, but the flash hole is blocked, you're going to get misfires.

I'd recommend depriming all of them and starting over by cleaning out the primer pockets. You likely can even get away with reusing the primers afterwards. I have not done so myself, but have heard from a number of people who have deprimed live primers and reused them with no misfires or failures to fire afterwards.
 
I agree with TimberPig... I'd deprime them and start over for safety sake. If I tumble after depriming, I inspect all of the cases and use a small finishing nail of there is any tumbler media stuck in the primer holes. It's a bit time consuming, but it works OK.
 
Be very carefull if you are going to de prime live primers. I personally would not try to save them, they are cheap. I would fire them if possable or soak them in water for a few hours.

Thanks,,just gonna deprime the little buggers,,A GOOD LESSON LEARNED..glad I didn't complete the rounds..
 
Knock the primers out carefully with your resizing die, no big deal. Primers are cheap, why risk a misfire or hangfire reusing them. Once my brass is cleaned they go into a loading block primer pocket up so the flash holes can all be checked.
 
I use fine ground walnut shells. I add jewellers rouge and some case cleaning media. I NEVER have a problem with media in the primer pockets. Tumbling after sizing has the advantage of cleaning the primer pocket as well as the case.
 
I polish after depriming and then use a push-pin to clean out the flash hole when there's a bit of corn cob stuck in there. However I've noticed a difference between cleaning media as to what portion of casings have to be poked out. The Lyman media I have usually leaves a chunk of itself in the hole. The RCBS stuff I've used most recently, sometimes, gets lodged in there. The Lyman is just coarse enough to get caught up. The RCBS is fine enough to pretty much pass through. Both have done excellent jobs in the cleaning process though.
 
Didn't know you could deprime live primers, good to know.

I usually clean after resizing to get rid of the lube and clean the primer pocket as well, it doesn't take to long after that to clean out the flash holes.

I would be very careful with this as one can flash and it is quite the bang.
I would run the primed ones though a rifle first instead of trying to push a live one out with a decapping pin.
