Neither of my manuals have the 123gr Amax. They have 120 and 125 gr bullets. Can someone give me the min and max for H4350 using 123gr Amax in 260rem. Thanks

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.
