Lots of different ways to go about this. Some people decap first and then clean their brass. Once the brass is clean they resize. The theory being that you get a cleaner primer pocket if you use fine walnut shell as a medium. Of course if you use a power pocket cleaning tool it doesn't matter. I have and use a Lee universal decapper. A berdan primer won't break it. They will break a std. decapping/sizer die pin. Ask me how I know this. I load a lot of military brass from outer space.
Lee Universal Depriming Decapping Die
This is an extra step but so is seating and crimping with different dies.
I got tired of adjusting my seater die for 38 to 357 and back so bought another set of dies. Yeah, I've got money to burn.
One thing about dies, you can always sell them here for half of what you paid for them.
