Whats the difference and why can't you reload Berdan primed brass cases? I want to start reloading, but don't have the first piece of equipment. A buddy saved a bunch of brass cased ?Australian? 308 and I am wondering how to tell if it is Berdan primed and why? Any advice is helpful, as well as what tools/setups/kits should I be looking to buy? Should I buy a kit or components? I will be primarily reloading .308, 30/30, .223, 7.62x39, 9mm, 45acp, and .357/.38. What do I even need? Thanks
