[QUOTE="noel carlson, post: 362242, member: 16138"] MR, Where a sixty degree angle on the land wall matches the sixty degree angle of the engraving-band wall, projectile "floating" is aided. 5R geometry is good for this, but a three groove configuration has advantages that will eventually find place in the high performance barrel. Best, Noel [/QUOTE]
