[QUOTE="eddybo, post: 489256, member: 7194"] It must have been a recent change because new brass I used was probably bought in 2008. Measuring using a barrel stub made with my reamer to very closely approximate mid point of the shoulder, they are GTG. I was using a member of this forums brass for the fired cases and his rifle to test fire the new cases. I am not sure when his brass was purchased maybe he will speak up, I know he is aware of this thread. All of his once fired cases were very close in length using the method I used to measured them. I would expect some variances being that none of those once fired cases had bullets jammed into the lands to help hold the case heads against the boltface. I originally thought that I had a newer reamer and go gauge, but checked and my reamer is older. My gauge is newer. I cannot recall what my gauge states for dimensions but it is a .280 gauge -004. Unless the gauge manufacturer made some changes to the gauges to reflect the differnces I think nosler brass is okay to use. I will state that is only a sampling of one. I checked a few cases from my personal .280 AI and all of my cases were .003 than the other rifle. I did have a very hard time chambering remington 280 brass in the gun I was using to test the cases. My conclusin is this either none of the 280 AI nosler brass I have around is affected, or Dave Kiff changed the 280 - .004 gauges to reflect the saami specs. I can not say which occured. [/QUOTE]
