[QUOTE="Bob Wright, post: 1991804, member: 104363"] This^^^^. Check and see if your fired brass will easily accept a bullet. If it has any drag going into the neck, you have a tight chamber/neck area. Alternately, measure your fired neck o.d. to a loaded round. .004 difference is a good average clearance. Turning necks might be in the equation. Second, your "trim to" length needs to be consistent and to your loading manual. Third, a hard carbon deposit may be in the neck area adjacent to the throat, causing your brass to pinch the case mouth, driving pressures up. It may be something more like a bad chamber job, but these are easy inspections I would start with. Know anyone with a borescope? [/QUOTE]
