In a passing conversation with my tool and die maker the other day. I asked him the cost to make a set of progressive dies for making brass or copper cups identical to the factory percussion caps minus the priming compound. He looked at a few Remington caps and said a minimum of $12,000 to make the dies. Then you would have to figure the cost of brass or copper stock, roll slit where it would feed the press on a roll feed in order to be cost effective. He said you would have to sell 750,000 @ .02 cents a piece before you would start to see a profit. Who ever bought the finished cups @ $2.00 per hundred, would still have to load with primer in order to have a functioning cap. Just a passing thought that I let float on down the river.
