Good day all. I recently came into possession of a whack of .303 ball ammo, Berdan primed, headstamped U 60 MK7. I believe it to be South African, made in 1960. Some of the rounds are discoloured, I'm assuming from bad storage, but they don't look unsafe to shoot. We all know how hard it is now to find good milsurp ammo. In amongst the lot were some DA and DIZ (Boxer primed) and one lone DC16 round (WWI). I've been shooting Lee Enfields since before the Dead Sea was even sick, but I've not shot the SA stuff. My question for you guys is has anyone encountered this same ammo before? Though I value opinions, I'm more interested in actual experience with old ammo showing the same characteristics. IMHO, it's probably safe to shoot since for plinking ammo. I took the liberty of attaching a pic with a clean round in the middle. As you will note, some of the rounds are almost a copper colour.
