[QUOTE="Gerard Schultz, post: 1078626, member: 51"] Darkker, That thread is about bore and groove diameters - matching the bullet diameter to the barrel and so forth. It is of no relevance at all. My question specifically relates to whether the BC changes if you have more or less lands in the barrel. It does not matter what cartridge we are dealing with, it could be a 300WM or a 50BMG. Does a four groove barrel give a lower or higher BC than a polygonal barrel? Or does a 5R 5 groove barrel increase/decrease the BC over a four groove barrel, and so on? [/QUOTE]
