[QUOTE="Bullet bumper, post: 1309682, member: 17844"] Where a certain bullets surface contacts the lands is dependent on shape of the ogive curve and at what point on that curve the bore diameter comes up . Long slender ogives will go further into the bore before the bore diameter jams . Short blunt ogives will go less into the bore . It will always jam at the bore diameter but the length from there to the base will vary between different style bullets . That is why you may get one particular style of bullet to the lands and not some other styles. Flat base gives more seat out room than a boat tail of the same ogive shape and same total length .
