[QUOTE="VinceMule, post: 2914213, member: 122164"] A tube micrometer should be used to measure the thickness, And a regular micrometer that measures the .0001 would help you decern dia of the neck change and neck wall thickness. The bright ring around the end of the case mouth indicates that the end of the case is scraping somewhere. Magnum's and Sherm's posts are noteworthy. A carbon ring at the end of the chamber may create a slight bulge when the case is chambered, similar to if the brass is just too long, the magnum's post of "look in the chamber" is the first and easiest thing to do. If you blacken the end of the case mouth with a candle or cigarette lighter, chamber the round, if it is touching either carbon or end of the chamber, it will rub the soot off the end of the case mouth.
