I've started to reload berdan primed cases, and it's no big deal.
I shoot a lot of 7.5X55 Swiss. I do have boxer primed cases, but they are not cheap, and I hate to loose one in the snow or the like. So my first step was to deprime. I use the hydraulic method. I made a collar to support the head of the case but not the primer , then I made a tight fitting rod to enter the case mouth. Fill the case with water, place the rod into the case mouth, smack rod with hammer. Voila primer is gone.
Berdan primers are available from North Silva. (Find Anschultz web page, then look up the Canadian dealer, same people.)
Primers are $15.00 for 250. Works out to 2X the price of a boxer primer.
I use the lee Auto prime 2. Because the Berdan Primers are 5.5mm diameter, a bit bigger then boxer primers, I used needle nose pliers and place 1 primer at a time on the ram to prime a case instead of the auto feed. The crimp on the GP11 cases is no big deal and the cases prime easy.
Loaded my usual load of RL15 powder and Hornady bullet and the Berdan primed case shot the same as a boxer primed one.
I personally would not do a .308 case, as I have been hording .308 cases for over 20 years now, but I will keep reloading Berdan primed 7.5 Swiss cases.
I no longer see Berdan primed cases in a negative light.
