Hey Larry,
I can understand your reasons for wanting to be able to use Berdan primed brass. I, too, hate to throw away good brass, and time is not a big constraint to me. Now, having said that, what follows is really negative feedback.
Consider replacement with new Berdan primers: Berdan primers can certainly be removed with a special tool that is easily available, and the brass can then be re-primed with new Berdan primers and once again loaded. To me, there are two problems with replacing Berdan primers. The first is the removal of the spent primer. I know it can be done with the special tool, but it is a bother to me. The second factor is the high cost of Berdan primers today and the fact they are hard to find. I simply cannot being myself to pay more for Berdan primers than I do for regular primers.
As far as converting Berdan primed brass to use Boxer primers, I have also tried doing this with no satisfactory results to my way of thinking. Besides removal of the Berdan anvil and making a centered flash hole, there is also the whole problem of Berdan and Boxer primers being different sizes. I am not saying that it cannot be accomplished, but it is far more effort than I am willing to expend, and I am one of those guys who spends a lot of time casting bullets and loading on single stage presses.
When it comes to reloading for hard to find brass, I considered this to be the case with 7.62X54 Russian and 8mm brass. Neither are easy to find locally, but I simply gave up the idea of converting Berdan brass and ordered a case of each in S&B Boxer primed brass.
I have given up on the idea of using Berdan primed brass for the above reasons, but that does not mean you should do the same. In any case, enjoy what you are doing.
Best wishes,
Dave Wile
