I read in Olson's book "Mauser Rifles" 3rd ed that the Czechs M23 case had a central drilled grooved anvil. This would allow de-capping with a conventional boxer arrangement. My question is: Has anyone done that? How would it affect pressures in a Berdan drilled case (i.e. central hole plus 2 smaller)? The reason I ask is that I have 5,000 Berdan LR primers and a ton of great Berdan brass. I could hydro de-cap once, drill, and then load as usual, plus use my /Lee trimmers.
