Hi! Looking for some 410/12mm brass head stamped shot shells in about 2" length empty or full for an old French gun. Most of them I have seen have been made by Eley or US Cartridge Co. and maybe other brands. They are not the ones that they first put out for this as those are marked 12mm CANNE or 12mm W.S. and are probably gone or used up by now. However these will work fine as they have the thinner rim thickness and I have one cartridge that a nice elderly gentleman gave me to see if it would work as he had one spare he said he could part with and it fits nicely. Also need some Good Berdan primers made by RWS #6507 or Eley #172 and there measurement is .254 x .133 I was told. If anyone knows what other Berdan primers will work let me know. I guess I'll be making some brass cases out of 444's or something similar if I can't find any that already fit but I thought it was worth buying some for a couple hundred bucks to save some work I don't really have time for so it is worth a try. If anyone has any that could use a welcome home let me know. Thanks!!
