For the record, burst-firing autocannons exist in canon. While AC caliber/etc is never technically defined (a class 20 AC seems to be any ac that can strip off a certain amount of armor, regardless of caliber or round burst), ACs that fire a rapid burst of rounds then reload are confirmed to exist.
It actually goes further than that - burst-fire ACs are (literally!) the rule rather than the exception.
- "Rather than firing at a single target, any type of autocannon can be 'walked' across two targets close to one another. An LB-X autocannon firing a cluster shot and Ultra and Rotary autocannons firing at multiple targets are a special case."
- "Determine the to-hit number for both targets and make separate to-hit rolls against each target, using the higher (more difficult) of the to-hit numbers and adding a +1 modifier for firing at multiple targets with a single shot."
- "If the to-hit roll succeeds, the target is struck by a single hit that inflicts damage equal to half the normal damage done by the weapon (rounded down)."

Essentially, the more basic rules found in
Total Warfare can be seen as simply assuming that all of the shells in a given burst land in the same general area.
For example, if each of the shells in a three-shell burst (such as that fired by the
Marauder's 120mm "GM Whirlwind" AC/5) hits the upper leg (e.g. thigh), lower leg (e.g. calf/shin), and middle of the foot, the entire burst "hit the leg".
Likewise, having each of the shells in a four-shell burst (such as that fired by each of the
Demolisher's 185mm "ChemJet Gun" AC/20s) hit the upper arm, elbow joint, lower arm, and hand is considered to have the entire burst "hit the arm".
From a more official fluff-wise perspective:
"The existence of weapon classes is an old point of contention among purists and the pragmatic.
An engineer or armchair general might hold forth that the Crusher SH Cannon Autocannon (the only useful part of a Hetzer wheeled assault gun) is a completely different sort of weapon than 185mm ChemJet Guns of the fearsome Demolisher tank, because the former is a 150mm autocannon designed to fire a cassette of 10 shells while the latter is a 185mm weapon that fires a four-round cassette. However, not everyone can afford the luxury of such nitpicking, and so militaries long ago adopted a scheme of rough classes to judge weapon systems. In the case of the aforementioned autocannons, military personnel and casual observers would consider both weapons to be “class 20” autocannons as they both fire 200 kilograms of ammunition in a 10-second period at an effective range of just under 300 meters. Any autocannon that falls into that range of performance is a class-20 autocannon, whether they fire a single 300mm, 200-kilogram shell or scores of 50mm shells. Thus all autocannon that deliver approximately the same mass of ordnance on target in the same elapsed time at the same range belong to a single class (in this case, AC/20)."
