[QUOTE="tinytree, post: 787330, member: 65938"] i recently got a box of hornady vmax 204s, and ran into the same thing. i figured it had to be the bullet lengths varying, so i measured all of them. there was .019 variation from shortest to longest in the SAME box of 100! the difference seems to be in the plastic tip, and evidently doesn't affect the ogive profile. i have used vmax forever, but have never run into this much variation. i contacted hornady, and they said .017 was their max acceptable variation range for the 204 vmax. i switched to sierra blitzkings and they have been very consistent, not over .006 range out of any box. all that being said, once i found the problem, and realized they were hitting the rifling at the same "jump", i went ahead and loaded them, and they shot fine. i agree that the published C.O.A.L.s are for magazine fit, and it is definitely best to work up your own ogive/rifling jump.
