Was chatting with Young Son last nite. Asked if he knew what "rifling" looked like.
"Yeah ... that James Bond spiral."
Close enough.
Nice video explains one of the methods of mechanical magic used to achieve rifling.

Theres days I feel that we live in an age of magic and wonder. So many clever things that are part of our daily life that folks take for granted.
