Heavy Stubbers seem to have larger barrels than Bolters. Autocannons are by far larger again. Yeh their mechanics are similar to a RPG, but their affects are the same as a 20/40 mm grenade, that is why I call them grenade launchers.

Heavy Stubbers have been said to fire normal .50 cal rounds, like our modern HMG's. Of course Autocannons should be in the 40/50 mm cannon range.
