Most of the 280AI data in Nosler #6 is simply reprinted data from #5, (24" barrel). The only data they re-shot with the 26" tube is that for the 140's and 160's, (I presume because the Fail Safe bullets were dropped from production.)
Since there isn't alot of factory chamber 280AI pretty hard trying comparing 7mag to 280AI. My 280AI dosen't have a barrel that match either Hodgdon or Nolser data I guess on paper data you might do it.
