PPC's should be like other energy weapons, and do damage as a beam (which is actually a series of individual hits like an MG, but the art and sound effects trick your brain a bit).
To me PPC's should be a tri-burst weapon and fire three shots in rapid succession.
That is what they're doing with the Clan Ultra AC, and probably because of the C-UAC-20 in particular. I think this also needs to apply to the PPC's, and then maybe we wouldn't have needed ghost heat?

Nah it should fire once but the damage should arc like lightning across multiple locations. So instead of doing all 10 damage to one location it might do 6 damage to one location, 3 damage to an adjacent location, than 1 damage to another adjacent location. PPCs are described as being similar to lightning bolts and we know it does electrical/emp damage so having it arc across locations makes sense.
"The tank's main weapon is the Parti-Kill PPC. Unlike other particle cannons, the Parti-Kill does not use an energy collection capacitor or similar chamber. Instead, it uses a series of magnetic collection bottles that gather their energy straight from the fusion reactor. These energies are then channeled through a larger magnetic bottle and released from the cannon. This fires an energy 'shell' that loses cohesion and disintegrates at 540 meters. The Parti-Kill's bolts are unstable at ranges under 90 meters." -

In addition to the above, every canonical reference to PPC fire from 'Mech- or tank-mounted weapons describes the weapon as firing a single bolt or pulse of what looks like "man-made lightning".
With regard to the notion of "arcing": a PPC bolt is described as looking like a lightning bolt, but it is nothing of the sort; it is a
particle beam weapon, not an
electrostatic generator.
"Consisting of a magnetic accelerator, firing high-energy proton or ion bolts, PPCs can flay armor through kinetic and thermal damage. While popular belief may hold that PPCs are an electromagnetic weapon, it’s worth mentioning that even though most PPC bolts look like a flash of manmade lightning, the actual electrical component of a PPC attack is little more than an intense burst of static." -

However, smaller units - namely, the Man-Pack PPC and the Semi-Portable PPC - can fire either single larger bolts/pulses or bursts of smaller bolts/pulses (for the burst-fire modes, the MechWarrior RPG rules for SMGs are used), according to page 110 of TRO 3026.
Coupled with how the various autocannons are described to work (see here), the only weapons that should be both "pinpoint" (e.g. be able to concentrate all of their damage in a single specific location) and front-loaded (e.g. deliver all of their damage instantly when the salvo connects) are the PPCs, the Gauss Rifles, and the UACs.
The rest of the weapons should be one or the other - lasers and burst-fire ACs (which is how
the vast majority of AC types work in the source material) would be "pinpoint" but not "front-loaded", while LB-X cluster rounds and the vast majority of missile launchers (where # of tubes ≥ # of missiles) would be "front-loaded" but not "pinpoint".
