For each 100% multishot one extra bullet is 'guranteed' and 'free' to shoot from the gun (costing only 1 ammo), the remaining 80% will be for a third bullet, but there's a 20% chance it will stay at 2 bullets.

Shotgun pistols like bronco has a more direct conversion, 7 pellets base + 7*1.8 = 19.6

So 19 guranteed pellets with 60% for 20.

Not sure what it does with beam weapons like the spectra, would be nice of someone could find that out.
