Since it seems next to impossible to buy percussion caps or the ones I'm finding are close to $10 a hundred, got me thinking. There used to be a line of replacement nipples that used small pistol/rifle primers. Now that it seems the primers are getting to be easily availabile again seems like a good thought. Anyone tried played with these nipples and are they still available. This is for tradition muzzle-loaders such as my T/C's...
