[QUOTE="LouBoyd, post: 345953, member: 9253"] Polygonal barrels have been around since the time of the Civil War. Qute a few Whitworth rifles were imported from England. They had hexagonal bores. This is a .451 Caliber. The bullet mold was shaped to match. They were among the most accurate rifles of the time both as small arms and field cannons. [url]http://www.whitemuzzleloading.com/images/whiterifles/histor10.gif[/url] There's no magic. An accurate rifle has to spin the bullet without excessive asymmetric distortion but with minimum blowby. Can a polygonal barrel do that better then a "land and groove barrel? After 150 years it's still debatable. [/QUOTE]
