[QUOTE="Rardoin, post: 1999961, member: 114954"] The 6.5 SS is based on the WSM case and has a magnum case head/base diameter. The .280/.280 AI is based on the .30-‘06 case with a .473” case head. Even if the case capacity is the same (I don’t know how close they are) you cannot necessarily substitute load data of one for the other. The case geometry is quite different and powder burn characteristics can be a bit different. [/QUOTE]
