[QUOTE="AKGuide, post: 1010989, member: 64701"] I have a tight neck chamber also in 300 RUM, but have found with FL resizing and bumping the shoulder .0015" that the ghost ejector mark is extremely faint and you have to look at it very hard and in the right light to see. Sometimes you will not see pressure signs with virgin brass as some of the energy is converted into expanding your brass to the chamber specs. I try to do all load development with once fired brass as a result of this. It was nice just decapping and trimming brass, but when I switched to FL sizing many gremlins went away. Reuben [/QUOTE]
