[QUOTE="MNbogboy, post: 2063356, member: 18849"] When anything seems out of place most likely it is. Very wise of you to question this anomaly. Neck clearance, donuts or carbon at the case mouth end of the chamber will all cause your "issue". Definitely not condusive to any type of consistency. If it is a neck clearance issue, the "springback" in your necks is the cause of your tight fired necks. Remedy will be to neck turn. If it is donuts as Kmccord mentioned it may be your transition of neck sizing and bumping the cause. Reaming and/or neck turning may be required for the fix. Carbon in the chamber is often the cause of a "tight" neck at the case mouth end of the neck. Here the case mouth is not allowed to fully expand and easily springs back to undersize. All three conditions could lead to higher or excessive pressure and IMHO should be addressed. Check neck clearance first (chamber dimension & loaded case). Inspect brass for evidence of donuts. Inspect chamber with bore cam for carbon that could impinge or restrict normal expansion. Hope you get it figured out. [/QUOTE]
