I recently bought a bunch of 80'ish S.A. ammo that's Berdan Primed (cheap!).
After playing around I've found that the primers aren't that hard to push out with water (hydraulic pressure). Will #35 boxer primers fit in these cases? I don't have any handy to check for size! |

the berdan priming system is completely different than the boxer system. there are 2 small holes with the anvil in the case. The boxer system has the anvil in the primer and 1 central hole. If you tried to force a boxer primer in a berdan pocket, I think it would be trouble.

Measure the primer pocket and see if it is smaller than your primers. If so, then you may be able to mod the cases to take boxer primers.
A primer pocket uniformer will shave down the anvil between the holes, and make it easier to drill a central flash hole. Measure the size needed from a boxer case and drill the hole. If your pocket uniformer opened up the pocket (squaring the shoulders of the opening), you will need to chamfer the edge to ease the insertion of the boxer primers. ymmv Bret |

I remember a while back a guy on the FCSA forum was doing this on a lathe. Can't remember exactly how he did it but he did get berdan primed brass to go bang with CCI-35s after considerable work.
Unless you just have a heck of a lot of time on your hands and the desire to make something work, i'd sell the berdan brass as scrap brass and buy some boxer brass. Boxer brass is pretty darn available right now and not terribly expensive. Prices have eased a bit with base metal prices decending. -David |

It'd be a shame to throw away a bunch of nice brass, but I'm sure it would take a lot of work to convert them. 
I don't have any empty boxer cases or loose primers right now, so I was wondering how much different the diameters were––they look pretty close visually, but I don't have anything to measure. |

Well dogbuster, No reloader is without a dial caliber. There is no way in hell you can reload without a dial caliber or a digital one. So open the old wallet and get yourself one. You will need it sooner or later so just bust the piggy bank and get one now. 
Max I have one––it's with my reloading stuff (and some #35 primers), too bad they are a long way off right now! The only thing I have with me right now is one empty case. I was hoping someone would save me some time by giving me the answers before I get back home to check it out myself!
