Apologies if this has been hashed out elsewhere, I did try searching but did not find what I was looking for (possibly confirmation bias, who knows). I've done some hand-loading of cut/formed 24ga Magtech brass and shot out of my Snider, I think pretty successfully. However now I need to RE-load this stuff and am struggling with the right equipment for de-priming.

I do have the Lee Snider dies, although waiting for delivery of the Lee Classic Cast Press which will fit them. HOWEVER... I would like to deprime the cases independently, as I'm not sure, having fire-formed the cases, that I want to deprime them.

I picked up the Lee Universal Deprimer - but it maxes out at .560, just shy of what I need for these wee buggers. Does anyone know of another large-sized depriming system that may work here?

Alternatively... outside of the frequently-used but possibly beyond my non-metal worker head... could anyone out there suggest anything else for depriming these cases?

Cheers,
Wade
 
Years ago, I used to use Lee Loader reloading tools - before I owned a press. I still use the de-priming rod for a 22-250 - in most cases that I want to de-prime - sometimes takes some "feeling around" to get the little pin into the flash hole - before I hit it with a hammer - I do not rely on the diameter of the thing within the case neck to keep it straight. My workbench has a 3/8" or 1/2" diameter hole - I can set a garbage pail under the work bench - drive used primers from the case through that hole into a bucket. I do have a metal lathe and did make a couple metal bases to hold various size case heads, but I am not sure those are really necessary. Maybe an idea for you?
 
As Blackpowderburner says, just use the pin from your dies. Drill a hole in a scrap piece of wood and punch them out. Even if I were resizing to use minies, I wouldn't run fouled cases through my dies. Another tip I learned from guys who had been shooting BP a long time was to throw the spent cases in soapy water at the range. I drift the primers out while the cases are still wet so that the pockets get a good cleaning along with the rest of the case.

De-prime as above.
Re-prime large pistol primers using a hardwood dowel with a blind hole drilled in the end to fit over the primer pocket inside the case. Or a socket the fits similarly. The Magtech brass is semi-balloon head.
Place one primer at a time on a smooth metal plate and drive the case down onto it. A mallet with a bit of mass works better than a lighter one.

I've done thousands this way over the years and even mashed a few primers that weren’t perfectly aligned without ever having one go off. Would still recommend gloves and glasses as minimum ppe.

I have decapped both Snider and brass shotshell cases while holding the case and the punch in a gloved left hand after setting the decapping punch with my right hand. It's easy.
a bench with a piece of 2x4 lumber with a small hole in it to catch the spent primer however is even easier!
Here's all you need.
I set my Snider bullets by hand as well.
I set the the new primer on the coin to set it into the cartridge if I don't have the vice or some other hard surface to set it on.
