South African .50 Bmg ???

[Navin85]

Hey im new on the forum and fairly new to the sport. I recently purchased some South African .50bmg Round that were in a sealed case. From my research, after the purchase i learned that they use beridan primers which are corrosive. Due to the corossive nature would it be recommened to pull the bullets and use the powder and bullet in a boxer primed shell? Also if anyone can shed some light on the South African ammo that will be greatly appreciated. Thanks in advance
