[QUOTE="backwoods83, post: 587206, member: 29890"] Cross sectional bore area, less lands typically means they cut tighter, more friction but also more accuracy in most cases, the different shaped lands R and C's also squeeze in a different fashion but last longer and are easier to clean. Think of it like this, with a conventional 6 groove after the lands cut its just kinda skimming on through, take half of those grooves away and it has to be tighter (only by about .0005-.0007") to spin the bullet up as fast, less surface area. I don't know if that explains it for you or not, but this is from my observations, kevin cram, kirby allen, or shawn carlock may have a better explanation. [/QUOTE]
