COAL & OGIVE ???
The COAL to the lands very in lenght from bullet lenght. The Ogive COAL should always be the same, but it's not this puzzles me. The lead angle of the lands does not change, but the bullet angle will very some in the same weight bullet & a lot in another weight bullet, where as it does not make contact at the same OD of the bullet or the same ID of the land's. .300 is .300 unless it's bullet OGIVE, HELP is it the bullet angle contact that makes the OGIVE very. ???
