[QUOTE="MNbogboy, post: 826796, member: 18849"] A while back I did a small test with a small sample of twice fired, cleaned, sized & trimmed cases.....The weight vs volume test was done on the heavy three & light three cases of a 50 case lot with 3.5 grains of extreme spread.... These were Remington brand 25-06 cases expanded and fire-formed to 6.5-06....Volumes decreased in 5 of the six cases as weight increased (as expected)...With one exception the heaviest case had more volume than the lightest case!....I checked this three times....My conclusion was the brass distribution within that case was quite different than the others....In other words the internal shape may vary even in cases that weigh the same...As an after thought I wish I would have "sliced" the two extreme cases lengthwise and made measurements.... Granted this was one test and one instance but may be another reason to explain unexpected "fliers"...Even in complete volume tested cases....I would also have reason to believe that manufacturing processes could explain what I found and that "better" more expensive brass could have a better handle on this..... Personally I normally weight sort only after two firings and sizing, cleaning and trimming...plus or minus 1 grain...But my best sorting method is"placement in the group" during a session at the range using a sharpy on any suspect case heads and watching them on subsequent firings....Twice out of the ordinary unexplained results usually get them booted....I had at one time an electric tool etcher that I numbered every case in a lot....It was a lot easier to keep track of "bad eggs" back then...Maybe I should buy another one...
