Caliber is fluff for the size of the barrel that the shell or shells are fired from and no standard caliber has been set for any of the classes of Autocannon. Autocannons in a class vary by manufacturer and model. With the fluffed number of shells and caliber being specified, no Autocannon has been specified to be one shell fired for each "round" or burst of fire.
What does this mean for High Damage Alpha strikes?
Simple: Instead of the AC20 and AC10 firing a single slug that transfers all of its damage to a single component, it would fire a set number of smaller projectiles in rapid succession that each deal less damage, but totaling in the same amount.
Up close and Stationary targets would still take the majority of damage to a single component, but moving and twisting targets would spread out damage due to the "burn time" duration of the shot, each slug potentially hitting a different component because of Time to Target.
For example:
AC20 = 4 Shells @ 5 Damage Each
AC10 = 2 Shells @ 5 Damage Each
UAC5, AC5, AC2 = Unchanged.
OR:
AC20 = 20 Shells @ 1 Damage Each
AC10 = 10 Shells @ 1 Damage Each
AC5 = 5 Shells @ 1 Damage Each
AC2 = 2 Shells @ 1 Damage Each
