[QUOTE="bigngreen, post: 1906784, member: 13632"] When we fire headspaced brass, especially new brass the base to shoulder or headspace moves and since our bullet jump when a bullet is seated of the lands is based on the shoulder to ogive we see a change in jump from one headspace to another, I've seen it change a fair bit on some rifles not much at all in others. Base to Ogive is a comparative measurement but not an actual reflection of the chamber unless you subtract your headspace measurement. [/QUOTE]
