Small pistol primers are not cheap either and I would rather save them for my cartridges. I still think for anyone who is stuck purchasing a #10 or 11 percussion cap maker and Prime-All is the way to go. Some hobby shops sell small sheets of copper that I prefer over soda cans or Mcmaster. Though using small primers is a great option.The video on how to adapt small pistol primers to shoot on a percussion lock was interesting.
