Okay, I changed the stats in one area and modified them in another plus added a new rule to cover the earlier mentioned "recoil" in the flavor text-thoughts?
Note: Please note that this contains some custom material from my own custom 'verse and material from the Metal Gear series of video games and is my first attempt at creating a unique weapon of this nature for a player's suggestion.
Capsule: The Ballista-class of Rail Gun was one of the last experimental weapons to come out of the design labs of United Galactica in the years shortly before the events of the United Galactica Civil War and the "Long Dark Night" that occured afterwards but this weapon was left in the weapon design labs on the planet of Northrend for a hundred and twenty years before it was accidentally discovered by a woman known only as "Fortune" who took the only two in existance with her during a mission on the planet by the black operations unit that she was apart of.
The Ballista prototype allows a person to use a man-portable rail gun which while compact packs as much firepower as a tank turret and can punch through pretty much anything (within reason) that it's used against and like all prototypes, it's got a few bugs mostly due to it's recoil due to a design flaw with the inner rail electromagnetic release system which while granting it's ability to fire a projectile the size and weight of an average pencil through even the toughest armor, it produces enough of a recoil that it requires a strong grasp or powered aid to keep the weapon from bucking out of the wielder's grasp.
As previously stated only two prototypes of this weapon exist-both in the hands of the PMC known as "Werewolf" (as Fortune is a member of this group along with the other members of her old black ops unit).
Name: United Galactica Weapons Developement Labs Ballista-class Rail Gun
Type: Electromagnetic Rail Gun
Scale: Speeder
Skill: Blaster Artillery-Railgun
Ammo: 40
Cost: Unknown
Availability: Rare
Body: 2D
Range: 5-50/500/2000
Fire Rate: 1/2, Delayed (see below)
Damage: 5D
-Melee: STR+2D Physical (Blunt)
Game Notes:
RATE OF FIRE (1/2, delayed): This weapon has a specific rate of fire for how it functions. Because of it's charge time before discharging it's energy beam, the operator will have the last initiative in a combat round. If they are attacked, Dodge, or any other appropriate action to distract them, the weapon's charging stops and must start again. This is the "delayed" portion of the fire rate. Further, because of the time needed to cool down the weapon before it can fire again, the operator must wait a full round before making another attack with the weapon. This is the "1/2" portion, as it operates similar to a turbolaser weapon from the Star Wars setting.
CHARGING: The rail gun needs to charge up for 1 round before firing each shot.
RARE: There are only at present two Ballista-class Rail Guns currently in existance despite however there have been rumors that somewhere a factory rushed several production models into existance but as of yet, these rumors are unfounded.
HOLDING: The character must have a Strength of 5D to hold the gun due to the recoil. _________________ "I've never seen a sloppier, more amateurish operation in my life... If you ever do something like this again -- count me in!"

Took a look at the ammo=40. How massive are the projectiles? |

I've got it set that it shoots a projectile which is the same length/width/weight as a standard number two pencil. _________________ "I've never seen a sloppier, more amateurish operation in my life... If you ever do something like this again -- count me in!"

You need to write in what happens to those who don't have the min str and still want to carry it/fire it. Also since it has powerful magnets and coils, anything special happen if its destroyed? _________________ Confucious sayeth, don't wash cat while drunk! |

I would think something more dense would be a better choice - less wind deflection and more penetration. So either more massive or smaller. |

Bren's, got a point, here. He can be annoying that way.
But, a easy workaround would be to use projectiles that fire a lighter substance with penetrator core made of a denser, harder,substance. That would not only work, but would also not require you to redesign your weapon.
It would even make some sense, too. The lighter material would be cheaper and probably fragment upon impact, creating nastier wounds, while the penetrator core would penetrate through armor and damage vital organs. Oh,and the ammo might be cheaper that way, too. |

That said, a denser round would probably be more accurate. _________________ Or that excessively long "Noooooooooo" was the Whining Side of the Force leaving him. - Dustflier

Haven't weighed one, but from a google search it looks like the mass of a pencil is 6g - 10g and it's made of wood, graphite, and clay binder - which are relatively low density materials.
Using something like tungsten, iridium, or some Star Wars hull metal would give better penetration. Since the weapon is speeder scale, I assumed it should have some anti-armor capability rather than being predominantly effective against soft tissue. Hence the need for a more dense projectile. |

A piece of straw is even lighter, but the winds of a strong tornado can drive one into a telephone pole.

Yup. Although as I mentioned earlier, a light projectile with a penetrating core would work as well, and save on the R&D work. |

Hurricanes just aren't all that fast.
- Category 5 hurricanes starts at 157 mph.
- Highest surface wind speed (which appears to include hurricanes) 253 mph.
- Fastest speed for a tornado is 318 mph.
- 9mm Parabellum 886 mph
It also seems like a straw compared to a telephone pole is probably a lot closer in density than a pencil compared to tank armor. Anyone know what the density of straw is compared to the density of different woods? |

Note he said "tornado" not "hurricane". The difference in maximum wind speeds in the center of a EF5 tornado v.s. a hurricane could potentially be over 100mph. I doubt that is enough to make a difference, though, or even any wind speed low enough that it doesn't just whisk away the tree trunk as well.
That said, penetration is not how hypervelocity railguns work. They're not better hole punchers. They're solid matter vaporizers.
The relatively low density of a small comet versus the high density of a forest in Tunguska may be a better indicator than straw in a tree trunk, anyways. _________________ Or that excessively long "Noooooooooo" was the Whining Side of the Force leaving him. - Dustflier

I'm thinking that the material used in the railgun's rounds would have to be made of somekind of dense metal which is light but strong-kind of giving it 1D of damage while the other four d6 is the actual kinetic and magnetic energy put behind the round.
Does that sound like a good thought? _________________ "I've never seen a sloppier, more amateurish operation in my life... If you ever do something like this again -- count me in!"
