Logan Metesh, the Firearms Specialst at the NRA National Firearms Museum, was brave enough to shoot a caliber converted Thompson Center in .600 Nitro Express. According to the video, the barrel was made by Match Grade Machine.
The recoil and muzzle climb looked much tamer than I had imagined it would be.
Does anyone know what that confetti looking discharge was? A paper wad?
I was expecting recoil and muzzle climb similar to this example 9 years ago.
I was unable to find .600 Nitro Express as an option on Match Grade Machine. But I’m sure you can just call them to special order one.
Edit: This was a Thompson Center Encore. Logan contacted me to correct himself which he misspoke in the video.
