[QUOTE="Gene, post: 469512, member: 7402"] That is true, its the point where the fattest part of the bullet (called ogive) first touches the lands in the bore. Jump means the distance the bullet goes before hitting the bore, and jam means how far touching the bore the bullet is seated. Bearing surface: The length of the bullet jacket which actually is engraved as the bullet travels thru the bore. [/QUOTE]
