[QUOTE="ShtrRdy, post: 1905350, member: 40852"] I believe this could be caused by at least two possibilities. 1. The seating stem contacts the bullet at a different place than where the ogive is considered. If the dimensions of the bullet are not consistent you can end up with different CBTO measurement. 2. If the neck tension and friction are different from case to case the extent to which the bullet is seated can vary. I like to count on the firing residue inside the neck as the friction layer. I simply run a polymer brush in and out of the case neck once to burnish it slightly. [/QUOTE]
