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.
