[QUOTE="baldhunter, post: 2784897, member: 11853"] I've personally loaded brass with multiple ejector marks without any problems.If the brass is measured with a mic.,it probably will show a fair amount of case head expansion too.The brass I was using at that time was either Winchester or Remington.Even though I was getting ejector marks on the headstamps,I still had tight primer pockets.Fast forward to more recent times,I worked up some loads using Remington and Winchester brass for a rifle that were giving me good accuracy and velocity.I tried those same loads with Norma brass and was getting ejector marks and loose primer pockets.I checked the volume of the case with ball powder.The Winchester case held the least amount.The Remington case held about one more grain and the Norma held about two grains more.I backed off the loads about a grain and the ejector marks stopped on the Norma brass.After that,I backed off another grain to keep my Norma brass from getting over pressured.This showed me that the Norma brass was soft,not only at the case neck and shoulder,but throughout the whole case.I can easily run my loads up with the Winchester and Remington brass and get around a 100fps more,but it's probably better to use the Norma brass as my pressure indicator and know my loads are running at a safer pressure.
