In which mechs?
I ask, because as a Dragon pilot back in the day, I frequently ran into this in my Flame. I can explain what happens:
Your weapons converge on the point directly under your crosshairs the moment you press the fire button. If you have your ERPPC's in wide set arms (See: Dragon, for example), those arms are pointed inwards quite sharply. If your target, however, was twisting while you fired and your weapons converged on a momentarily close point (like his arm) then that arm twisted out of the convergence point, the PPC bolts will cross each other in front of his mech. They could either hit opposite sides of his mech or, in the case of a narrow profile, miss on either side.
Or, you may have fired at a leg, but had your weapons converge at distant terrain between his legs, causing them to not angle in nearly enough and miss, again bracketing nearby targets and missing on each side.
Or, if you have to lead your target a bit, the above effect can come into play again - fire with your crosshairs on the target, convergence is good but projectile speed causes them to cross immediately behind the target. Lead your target, and the PPC's converge at the distant terrain/skybox, causing the arms to angle out dramatically and potentially render particularly narrow targets moving at a good speed literally impossible to hit.
With slower moving projectiles, these effects are particularly noticeable. It's not actually a bug, just an unpleasant side effect of how convergence worked. Ironically, back when convergence was not instantaneous, this wasn't nearly as much of an issue.
