Anybody know of a source for Berdan primers in the States???

Good luck.

Grafs used to carry them, but I have not seen any there for a while.

Last I heard, some guy on Gunbroker was selling some, but I am not sure in what sizes. If they are from Russia, there is a decent chance they are corrosive.

I have almost no experience with berdan primers, but I do know they come in at least 3 different sizes.

I also know that you need a special decapping tool-RCBS makes one, but I do not like the design in which you basically pry the primer out from one side of the case. The better method seems to be to get some tubing with a plunger and rig up a device that uses water pressure to pop the primer.

And finally, if you are dealing with casings from fired ammunition, some cartridges will have crimped primer pockets. I seem to recall that there is another tool to decap crimped primer pockets.

Graeme Wrights book has a pic of a Berdan decapping tool.

I think RWS MAY make Berdan Primers.

I believe Shotgun primers can / have been used
as a substitute.

there are some on gun broker right now

2000 and 5000 count

i've got a few hundred stashed away in a drawer someplace that fit my old 450 3 1/4" if you need some
