[QUOTE="Freebore, post: 897636, member: 873"] I suggest you check your brass wall thickness in the neck area. It should be uniform all the around. Ask the 'smith what is the neck diameter of the finished chamber. You may have to clean-up your brass in the neck by turning just hitting the high spots. This is not usual but not unusual either in a custom barrel with SAMMI Spec chamber. It could just be I'm sure a min spec chamber. So the brass has to be cleaned up of high spots. Yes it is possible you may have a bad seating die. Call RCBS pretty good folks there. I have that issue with a 220 Swift. Lee die wont bump shoulder back enough but RCBS will. A Min SAMMI Spec chamber. [/QUOTE]
