Did I fix my reloading problem, do others do this?

[QUOTE="TnTom, post: 472685, member: 21944"] not uncommon that the expander ball tweeks the neck as the case hardens, cure is to anneal the case. If you are seeing .0025 out of the chamber you chamber is not concentric. If I'm understanding what your saying you are full length sizing repeating the stroke as you rotate the case to achieve a minimum indicator reading at the same time you decrease the life of the case as there is a degree of work hardening occurring from the excessive working of the case material. I'll F/L size new brass and pay little or no attention to run-out then load and once fire. At that time run-out should be less than .0005" if the chamber itself is any good, then simply neck size, there should be no increase in neck R/O. I anneal about every 5th firing and F/l size again at that time. I'll reload a case usually no less than 10 times unless I see some signs of cracks at the mouth then I'll toss in the bucket. Ive found R/O is usually the sizing ball tweaking the neck. Use some 2000 grit emery and polish the ball and be sure the case mouth is lubed before you size. I have found the FL die on one occasion with i.d.'s not concentric and returned the die. One way to determine is to remove the sizing ball, run the brass through the die and check run out on that case. If the neck is not concentric its in the die. [/QUOTE]
