[QUOTE="VinceMule, post: 2880227, member: 122164"] Some years ago, a friend took a lathe, removed the headstock, attached a computer with a long stylus. He could measure the twist rate in .200 length increments and plot on a graph. It was amazing how twist rate changes in a barrel. He also invented and patented a new Barrel button that does not tip. Anschutz and Pac Nor purchased those twist-rate measuring lathes that I know of. [/QUOTE]
