You can easily get 2800 safely in a 24" bbl, probably even a 22". I've never run the A-max, but have run the 162 Interlock a little bit. 60 grs of R-22 got me 2970fps. I've run several 160s in the near 3000fps range with that load with no problems. Quickload predicts that a 160 Nosler Partition can run 2990 with R-22 at 65K psi. (which is SAAMI max for the .270, and should be for the .280Rem) Id stick to the slower powders such as H4831, R-22, H7828, N165, and the like.
