Removing primers

[Hotwheels81]

Universal decapper in hole #1, FL die/rapidtrim in hole #4, bath in the ultrasonic after...

What is this "medium" you all speak of? Cleaning brass to me means getting crap out/off of it not putting a bunch in/on it intentionally that is more dangerous than what your trying to remove...

....3hrs to clean brass? Wow.

The crushed walnut shells used for industrial deburring of plastic parts etc., are the same as that used for lizard bedding. Acquired a part bag, for free, years ago. Got an unfinished C7 forestock too.
Doesn't really matter what order you de-prime. As mentioned, tumbling after does both, cleans the pockets and attracts the media. Haven't cleaned chemically myself for eons. Adds another step. So does having to remove the clotted media in the pockets though. No free lunch when reloading.
Uniforming the pockets is only done once, if you bother with it at all. Doesn't make any difference if you do it or not. It's a bench rest technique

Lol...why do you think the bench rest guys do it? For their good looks? It's just one of several small steps that add up to an accurate round.

Another vote of support for universal de-capping die followed by wet tumbling in SS pins. Working well for me.

using a tumbler to clean and polish the brass. throw it in and forget about in for a few hours

SS tumbling yields me some very clean primer pockets without having to manually clean the primer pocket - which is why I deprime before tumbling.

There are dozens different sizes of walnut media. Need to go to a place that sells blasting abrasives.

I agree with Sunray on this one- assuming they need "uniforming" at all- once would do it. If the pockets are changing after firing, they're likely stretched beyond further use. They sure aren't going to get any smaller.

Cleaning the pockets doesn't seem to make much difference either. I stopped cleaning them long ago.

ymmv.

I've read all sorts of statements that clean primer pockets give 'more reliable ignition', but I think that 'reliable' is not the correct term. It gives more CONSISTENT ignition. Primers still ignite reliably when seated over a pocket with burnt primer residue. Perhaps the residue absorbs some of the initial heat that would otherwise ignite the powder. Eliminating the residue reduces that energy loss (if there is one), and it also ensures that new primers will all be seated identically to the same depth and thus ignite more consistently.

Pet store lizard bed crushed walnut cleans brass just fine and doesn't clog the flash hole (major PITA with the $$$ 'special' stuff the gun stores sell). Much cheaper.The only thing it won't do as well as make brass pretty-shiny; a tablespoon of Brasso tossed in will handle that if shiny is on your list.

I personally deprime before tumbling as it's another step otherwise.
