[QUOTE="Bullet bumper, post: 1309901, member: 17844"] That's not correct . The lands are the bore diameter not the groove diameter . The bullet will stop some place on it's ogive shape at that bore diameter of the front edge of the lands if the lands are not eroded away that is. If a barrel is say .308 groove diameter size of the bullet , then the lands are around .300 diameter roughly speaking so the bullet jams some place because it's shank is .308 . There is only a few thou in it but it is on the edge of the ogive . [/QUOTE]
