This is about as close as you're likely to get. This might also qualify. As would this. And maybe this. The whole "assault cannon" thing (a completely ludicrous concept by name) most likely came from the "Cobra Assault Cannon" from RoboCop. They were just movie-fied Barrett M82A1's. :) |

Out of interest, why is it that semiautomatics are considered less accurate than bolt action?
I personally continually think of Assault Cannons as being similar to the Assault Cannon from Dark Forces. Man, that was cool. ~J |

I would imagine the added shift from ejecting the casing and chambering a new round.
Not being a rifle shooter, I can't swear from personal experience. -Siege |

When I think of an assault cannon, I picture a multi-fire multi-barrel weapon chambered for a 12-15mm round. I see the Panther Assault Cannon as a 20mm autocannon that can be fired from either the hip or on a bi-pod.
And to go a little off subject, the OICW might not be an assault cannon, but that does not make it no less deadly. The OICW advantage comes from its ability to launch a ABED or other wise known as a air bursting explsive device on a relatively flat flight path. This gives it a very big advantage over normal grenade launching devices as in you can easily shoot it though a window. And the fact that ABEDs can be air timed means you can program then to explode a few seconds after they land. Making the people inside the target think it failded to arm and no longer warrented there attention, then boom it detonates and there are dead or seriously wounded. |

The action of a semi-auto doesn't tend to lock up in exactly the same way every time due to the forces involved in cycling the bolt automatically. Therefore each cartridge is headspaced in the chamber slightly differently than the next, which can lead to inconsistent pressures and consequently velocity and accuracy (meaning consistency from shot to shot). The pressure variation is usually very slight, but the further away you are from the target, the more difference it makes. There are ways to minimize the lack of consistent lock up, but generally it takes a lot more money and time to make a super-accurate semi-auto than a bolt action. Being loaded manually, bolt actions can be loaded much more consistently and less violently, which will generally allow a bolt action to stay more accurate over a longer period of time. a nicely-treated action tends to wear a lot slower. There are a few semi-autos out there that will regularly outshoot a lot of bolt actions. But they usually cost an arm and a leg. For instance, a company called Tactical Operations makes rifles based on the Remington 700 action that are gauranteed by the factory to shoot 1/4 MOA groups (that's three to five rounds inside of 0.25" at 100 yards, 0.5" at 200 yards, 0.75" at 300 and so on). The rifles cost anywhere from $3,500 to $4,500 (no optics; tack on another grand or so for that). A Heckler & Koch PSG-1 doesn't leave the factory until it shoots 50 rounds inside of 1 MOA (1" at 100 yards, 3" at 300, etc). The PSG-1 could likely shoot just as well as the Tac Ops rifle, but it costs upwards of $10,000 (with optics), weighs nearly twice as much, and will probably require a lot more maintenance to retain that level of accuracy. But in both cases, it takes quite a bit of training for a person to be able to even utilize that level of accuracy. There are also tactical advantages and disadvantages to using each kind of rifle. |
