I like seeing alternative ways to do things. It’s good to have options. Others drop a pre-measured tube over and just trim with a knife. I see benefits of both methods 👍😎
I use a mini lathe, but then I do 1000s of shells for commercial starter blanks ( 12ga-30 and 60mm) and Film Blanks (12ga 65 mm Roll crimp) The Tube cutter gets a bit noisome after about 20 shells. But Horses for courses... Good Video. DocAV AVBFilmGuns Australia.
