I feel like this warranted another thread because it's a completely different option for those of us making our own caps. This idea dawned on me last night, and I know it may be a bit sacrilegious but I own a 3d printer that I bought for making parts for my airguns and slowly learned how to use CAD software. It took me a few tries but I made perfectly fitting caps and they do work with the priming compound in them. I can turn out over 100 an hour. And I'll still be making the forming die for the metal ones. This is a very good alternative. If interested, its as easy as buying the printer for 150, filament for 15 and sticking the SD card in and hitting "print." Im even willing to share the file with you all.
