    My only try at water depriming gave me expanded neck and shoulder and the primer still hadn't moved. I drill out the old berdan primer with a drill a little under the size of a shotgun primer and cut a recess for the rim of the primer. Then install shotgun primers. They seem to be a lot easier to find now than most other primers and a lot cheaper.

    Found this after searching for what to do with hundreds of berdan primed .308 cases I was given. Like a dufus, I did not know they were berdan primed until I had spent days cleaning them. So now what to do....sell them as scrap, find berdan primers, modify them like Larry has posted, or convert them to use 209's.

    I do not reload rifle calibers on the progressives so that may factor into how I proceed.

    I have read the whole thread and it was an eye opener. Watched a number of YouTube stuff as well.

    This is a great resource. Thanks to all that contributed.

    Thanks for the info everyone. I loaded up 9 steel case 7.62x39 to test out. It was successful. Small rifle boxer primer stayed in place. Shot them through an sks-m. Used .308 bullets because thats all I had laying around. Over 24 grs of DP2200. Next will be to experiment with cast boolits. And if there is anyway to streamline the process. The drilling takes awhile. Click image for larger version.
