M98, M70, or M77 (CRF) SAAMI .458 Winchester Magnum, with a standard 3.42" inside-length magazine box.
Load that box with 3.340" COL routinely. Single load with special purpose rounds up to 3.540" COL.
3.540" COL is the maximum, unfired COL that can be ejected by cranking the bolt of my rifles.
We can get about any .458-400gr bullet to surpass 2400 fps MV from a 24" barrel at 3.340" COL. That is really plenty for all-purpose use.
Special Purpose: We can get a selected 400-grainer over 2500 fps from a 24" barrel at 3.395" COL. We can get a selected 400-grainer over 2600 fps from a 24" barrel at 3.425" COL. The former works through the magazine of the Standard rifle, the latter does not. Single load the latter.
