If you didn't get any on the cheap (~$280-$300 per 480 round carton), then you are better off hand loading.
I've tried swaging and cutting out the anvil to convert the GP90 brass to boxer primers, and it was a fair amount of work with varying degrees of somewhat success.
Alternatively, PPU brass is pretty decent.
The Berdan primers that Canada Ammo had and maybe still does, work quite well.
I made up a two prong punch to knock out the dead primers from the case, with a hammer, over a base on my bench, with a hole for the spent primers.
When I size the milsurp cases, which are very good, I just take the decapping pin out of the stem, but leave the neck sizer ball in place. Of course, I still back off the stem.
The brass used by the Swiss for their GP11 ammunition is very good.
I've got close to ten reloads on 60 unaltered Berdan primed cases
I was using an RCBS Berdan decapper tool, but it's a pain in the butt/hand. Fine if you're only doing 20-30 cases at a time but it's god awful slow.
Before I got the Berdan primers from Canada Ammo, North Sylva was my go to supply business.
I have several obsolete cartridges that I hand load for. In some cases it's just a labor of love, because I just like shooting old transition type rifles, such as the 8mm Kropatschek. The rifles were built by Steyr and in VG+ condition, inside and out. They shoot very well. Smooth as oiled glass actions with fitting that would make modern firearms builders blush if they were compared side by side.
