Mysteries Revealed: How Cut-Rifled Barrels are Made
For anyone interested in accurate rifles, this is absolutely a “must-watch” video. Watch blanks being cryogenically treated, then drilled and lathe-turned. Next comes the big stuff — the massive rifling machines that single-point-cut the rifling in a precise, time-consuming process. Following that you can see barrels being contoured, polished, and inspected (with air gauge and bore-scope). There is even a sequence showing chambers being cut.

Thank you, Mr. John Krieger and your crew for all the great barrels.

interesting question would be why all gusmithing videos use identical tune?
Lots of steps in the process! Cool video
It’s generic stock music that isn’t particularly offensive to people(unlike say, generic metal or generic electronic),and is either cheap or free to use.
