Though this leaves me wondering about the path of destruction that is 'left out' of this explanation when we go this route. We should have small explosions going in a cone, affecting potentially multiple targets especially as we go further out. And with this fluff explanation, we're left with something that doesn't quite fit.
To a point, that consideration is at least partially addressed by the Multiple Targets rule for LB-X cluster rounds (
Tactical Operations, pg. 100).
"For an LB-X autocannon firing a cluster shot, make a single to-hit roll against the highest to-hit number plus 1. If all damage is applied to the first target after a roll on the Cluster Hit Table, then no additional damage is applied to the second target. However, if some of the damage missed the target, use that 'missed' Damage Value as the new number to roll on the Cluster Hit Table to determine what damage struck the second target. For example, a controlling player rolls a 7 on the Cluster Hit Table roll for an LB 10-X, resulting in six 1-point Damage Value groupings hitting the first target. That leaves 4 damage and so the controlling player would then roll on the 4 column of the Cluster Hit Table to see what damage is applied to the second target."
As "both targets must be in adjacent hexes and within range of the weapon", this would indicate that a single LB-X cluster round could be spread/"walked" across two targets that are as much as 30 meters apart (e.g. center-to-center distance of laterally adjacent (relative to the viewpoint of the attacker) hexes).
However, it is obvious that spreading the damage between two targets 30 meters apart at a range of 100 meters requires a very different (and much larger) spread angle than spreading the damage between two targets 30 meters apart at a range of 500 meters (on the order of ~8.62 degrees at the weapon's muzzle for 100 meters versus ~1.72 degrees at the weapon's muzzle for 500 meters).
Shrapnel-style proximity-detonated or timer-detonated shells, by their very nature, cannot achieve that level of flexibility/variability in their spread, as they tend (by design) to focus their submunition release in a relatively narrow area in front of the shell's path-of-travel (see the Wikipedia graphic, below) - which, incidentally, is one of the main reasons why some MWO players have advocated for that style of implementation (see Bishop's graphic
here).
"
The explosive charge in the shell was to be just enough to break the casing rather than scatter the shot in all directions. As such his invention increased the effective range of canister shot from 300 to about 1100 m."
"
In addition to a denser pattern of musket balls, the retained velocity could be higher as well, since the shrapnel shell as a whole would likely have a higher ballistic coefficient than the individual musket balls."
That exact problem can - and, since approximately 1950, has in reality - been addressed in real-world shotguns by the idea of an adjustable choke mechanism.
Imagine: a servo-driven variable/adjustable choke system slaved to the "Mercury-VII targeting system" (cast as essentially a dedicated
gun data computer for the LB-X ACs which is, in turn, slaved to the 'Mech's Targeting-Tracking System (which serves as a
director/predictor)) with the choke being set to "fully open" when firing LB-X slugs or when firing LB-X cluster rounds at extremely close range (to allow for relatively wide spread), being set to "full choke" when firing LB-X cluster rounds at long-range targets (to allow for narrow spread, to concentrate damage against distant targets), and having intermediate settings for targets at intermediate ranges (where the Mercury-VII unit automatically adjusts the gun's choke setting based on the range-to-target).
The presence of such a system would help to explain the high price difference of the LB-X weapon itself (400k c-bills for a LB 10-X, vs 200k c-bills for a standard AC/10), as well as the lack of ammo interchangeability (e.g. why a LB-X AC of a given bore size cannot simply fire standard AC rounds of the same bore size, instead requiring specialized "standard-esque" rounds that cost twice as much (12k c-bills/ton for LB 10-X "slug" rounds, vs 6k c-bills/ton for AC/10 standard rounds), which would be designed to account for the presence of a choke mechanism on the LB-X weapon).
