[QUOTE="Huntsman66, post: 2784240, member: 117569"] I have noticed the same issue… not to the extent you did, but still surprised me a little. Had a box of Nosler bullets and grabbed the next in line and they were 14 thou different from the previous box. But correct me if I’m wrong, but if you are measuring to the Ogive thats the first contact point for the lands. So the relationship between the BTO and touching the lands of the barrel should remain the same even if the over all length of the bullet changes a slight amount. Thats why you dont use COAL when setting your jump, because of those variables… [/QUOTE]
