I believe most military 8mm is berdan primed, which means there are 2 holes in the bottom of the brass, and there is not one big hole in which to punch the primer. Last I knew this meant they were not able to be re-loaded. Maybe over the years someone has invented a system.... There will be plenty of folks here to tell you all about it.

you can reload Berdan primed cases but it's not worth the hassle.

It's not so much about the hassle of depriming berdan primed cases, if your setup to do it.

But it's much harder to source the primers, as there's no standard sizing with berdan primers, and ya need to get the size of primers suited to that calibre. That's the big headache about it.

Depriming 8x57 Berdan primed brass, then repriming, is not a problem. Finding the primers is. You also have to worry about Berdan primer diameter and height, as there are a zillion sizes.

There may be another supplier that brings in Berdan primers soon: Wolf. Thankfully, most Berdan brass you encounter, except most 7.62x54R and .303, will be .217" size.

PMC was the last company that brought them in (.217" only), and that was about 7 years ago, and all those are gone. RWS brought in many sizes, but have not in over a decade.

There are many manufacturers around the world that make Berdan primers, just nobody is importing them.

22LR, play on words, you say the 200 cases have corrosive primers, does that mean the primers are live, not fired? I have 500 8X57 cases that have live primers, I wanted the powder and bullets, I did not want the primers, I formed 8X57 cases from 30/06, corrosive ammo at $4.70 per 70 rounds, from .01 to .08 cents each for 30/06 cases and $15.00 for a forming/trim die plus time made the effort worth while. I have not considered using the Berdan primed cases, all are like new inside and out, this speaks well of the way the ammo was made and stored.

I thought about loading Berdan cases, the Ol' Western Scrounger talked me out of it, he said he would sell me the primers at about the same price as bullets, 15 cents each, I also considered making two different type swaging type tool to reduce the diameter of the primer pocket, I got over it, I purchased case forming dies instead.

Ya ive got 200 rounds of live ammo right now that im wanting to shoot but not sure if the brass is usable or just through it away. Im leaning towards just saving them for now and getting my 30-06 set up running first.

If you need 8mm brass what I do is wait. Winchester runs 8x57 brass once a year. Thats why you can only get it some times.
Or I make 8x57 brass out of 30-06, 280 or 270 brass any time of year.
You can always save the berdan brass and turn it in for scrap, brass is worth at least a couple dollars a pound.
I have an old turkish mauser. I have cronoed 185gr SP at 2880, the 28'' barrel and rounds loaded with winchester 748 untill 2-3gr shy of the first high pressure signs.

Privi is selling 8mm brass... at least 8x60.
Pick that up and trim to 57mm :)
But I think they sell 8x57 as well
