Few years back, before the price went through the roof, I picked up a couple of battle packs of South African .308 ammo. Good stuff, though Berdan primed.
Got to wondering if those Berdan primers I'd picked up would fit, so deprimed and resized some brass I'd saved, and tried them; fit perfectly.
Loaded up twenty rounds with my standard cast-bullet practice load for such cartridges, and tried them this morning. Worked perfectly.
That makes 7.5x55 Swiss, Yugo 7.62x39, and now that .308 that will work with them. Makes me glad I saved that stuff.
