Hornady manual:
Warning! Notes: rifle: Remington 700; barrel: 24 inch, 1 in 8 inch Twist; case: Remington; primer: Remington 9 1/2; bullet diameter: 0.264 inch; maximum C.O.L.: 2.800 inches; maximum case length: 2.035 inches; case trim length: 2.025 inches; NOTE: USE 129 GRAIN BULLETS DATA FOR LOADING THE 120-123 GRAIN GMX OR A-MAX BULLETS.
Sometimes what seems like it should work, doesn't.
I noticed this when researching loads for 6.5CM, Hornady has the follow note:
Warning! Notes: 120-123 grain bullets Hornady #26110 GMX #26172 A-Max or #26171 A-Max; COL: 2.710"; rifle: Remington 700/Custom; barrel: 24", 1 in 8" twist; case: Hornady; primer: Federal 210M; bullet diameter: 0.264"; maximum COL: 2.800"; max. case length: 1.920"; case trim length: 1.910"; use maximum loads with caution.
In the case of the CM, all 120-123 are listed as same load data.
