as for not bothering with berdan brass? I disagree. If its a hard to find cartridge and you like to shoot it a fair amount, berdan brass can be used.
You have to decap it differently, yes. It takes longer to decap, yes. And Berdan Large Rifle primers are harder to find. However, if your brass is getting expensive and/or hard to find, its worth it.
you can either decap it and clean up the crimped pocket(if it has it), and then prime with Tula primers, then load as normal. This is fairly easy. Definitely takes longer, but not the end of the world.
or you can convert the decapped brass to boxer. This is much more work initially, but once done, you are set and can use it just like regular boxer brass.
I recently bought a bunch of 8x57 brass that I thought was boxer and it turned out to be berdan, so I am going to attempt some conversions. I already do Berdan reloading with the Swiss rifle, so I may try something new.
oh and just because there is a central hole and no primer in the pocket doesn't mean its boxer brass...
