Reloading .303 British : Berdan Primers

This link below has a lot of useful information on Berdan primers including sizes and what they're used for. Acquiring Berdan primers in Australia seems to be impossible these days, especially the RWS 6000 primers that were used in the 303. I don't even know if RWS produce them any more. At the present time all primers, including boxer primers, are in very short supply in Australia, especially pistol primers.

If you intend to reload ex-military 303 Berdan primed cases, be aware that if they've been fired with primers containing fulminate of mercury, the cases are essentially ruined. The mercury gets into the brass and makes it brittle. There's a high chance of the brass failing on the next or subsequent firing. Most early 303 military ammo was loaded with mercuric primers which as a general rule can be identified by the copper color of the primer cup. If the primer is brass colored in appearance it's a fair bet it's non-mercuric. Some post WW2 303 ammunition while still loaded with cordite was loaded with non-mercuric primers and can be reloaded if you can find the correct Berdan primers.

Either way, reloading Berdan brass is a pain. It's far easier to just stick with modern boxer primed cases.
