J.P. Gemmer's Rifling Machine Makes Barrels in 2025 | Muzzleloading History - I Love Muzzleloading

I've seen that machine in use, way back in the 1980's at the Hawken Shop on Lindbergh Blvd. in St. Louis County. I had come in with my dad because I was interested in muzzleloading firearms. So he and I stopped in and I was shown that machine while it was being used.
