Dogmann, I did a quick google search and found no website, which was exactly what I expected but wasn't sure. I do know the man who started and ran Gonic Arms died 5 +/- years ago, maybe more, and his son tried to take over and run things with meager results. Didn't find anything on current status of the company. There was a gun shop in New England that handled most of his sales and seemed to be pretty close. Renaissance Arms, I think, is it's name. They do have a web site, but a quick glance showed no mention of anything about Gonic, but a phone call there wouldn't hurt. I also know that Cecil Epps at Precision Bullets at one time had sabots made expressly for the tight bored Gonic 50's. A call there wouldn't hurt either as I find Cecil quite knowledgeable about all things muzzle loadable.
