Bill Davis used to make them. He lived in Florida, but moved his business to Utah now. I just checked his site and found this message.
We are updating our site and products, and relocating our business to Utah.
Orders already accepted/processing will be filled before the move, but we cannot accept new ones
until we are done moving, which can be as late as April 2008. We apologize for any inconvenience,
for questions please call at 352-473-0380.
Bill makes a good bullet. His turn around time was getting a little slow I was told, although I never had a problem with Black Jack Hillwhich is the company Bill Davis owns... Give him a call and see if he is in operation. I would guess he is not but you never know. He sells a wide selection of muzzle loading bullets like the REAL bullets, and some other ones..
