Editing Gauss (section)

=== Imperium ===
Strangely enough, heavy bolters use coilgun tech to further accelerate its bolts, so they can use much lighter ammo with less gunpowder (as real life gyrojets have shown, more "kick" is needed to make it viable at ranges below a dozen or more meters).

Also, the [[Nova Cannon|NOVA CANNON]] is sometimes described as fuckhuege railgun, though this is only one of a half dozen completely different explanations of how the NOVA CANNON actually works. (which is actually surprisingly fluffy, when you think about it.)
Macro Cannons, the Imperium's go-to for ship-to-ship broadsides each utilize a massive coil gun in the outer muzzle shroud to accelerate their shells even further.

Other possible Imperium Gauss weapons are [[Autogun#Accelerator_Autocannon|Accelerator Autocannon]] of the Sicaran Tank, the [[Accelerator_Cannon|Accelerator Cannon]] of the [[Fellblade|Fellblade]] and the Macro-Accelerator cannons on the [[Astraeus]]. If not they are gravity accelerated like Eldar [[Shuriken_Catapult|Shuriken Catapults.]]
Since all but the Astraeus are relics that even the most adept [[Techmarines]] and [[Tech_Priest|Tech Priests]] are too paranoid to mess with. Modifying these weapons for other platforms or using them like [[Havoc|Havocs]] armed with [[Autocannon|Autocannons]] are unlikely. With [[Cawl]] being the sole possible exception.

For the record the [[Galvanic Weapons]] used by the [[Skitarii]] and [[Secutarii]] are not coil-guns despite the fact that the term implies it uses electric currents. The chemical reactions would mean that they are [https://en.wikipedia.org/wiki/Electrothermal-chemical_technology Electrothermal-chemical] weapons powered by a battery.

====Magnarail Lance====
[[File:Magnarail_Lance.JPG|200px|right|thumb|Magnarail Lance]]
Possibly the only known handheld Imperial rail gun (as of yet). The Magnarail Lance is one of the primary weapons of the [[Tech-Priest Manipulus]], with the other one being the [[Sonic Weaponry#Transonic Cannon|Transonic Cannon.]] The Magnarail Lance is an odd-looking railgun in all honesty. Resembling more like a harmonic pitchfork, the weapon is externally conducted by two electromagnetic rails, that launches the projectile within the barrel.

On the tabletop, the Magnarail Lance is an 18" Heavy 1 S7 AP-3 weapon that deals d3 damage or a flat 3 damage if the bearer did not move. Can go up to 21" range if you use the Manipulus' bolster weapon rule.

In contrast to the Transonic Cannon which deals with hordes at close range, the Magnarail Lance is designed to terminate vehicles and heavy armor from longer ranges. However, by doing so, it limits the Manipulator's other weapons and equipment which are all at close range.
