Not sw.. In many other movies they do reload..sometimes with much frequency (die hard!)

Yeah, but more often you get the guy with a revolver shooting a dozen or more times without reloading (see Raiders of the Lost Ark), or someone with a SMG or assault rifle blasting away all day long on full auto with a 20 or 30 round box magazine.

Reloading in movies is not realistic at all.

David Drake is one of my favorite military Sci-Fi authors, and a lot of the tech he features makes for some interesting conversion ideas. In this case, in his novel Redliners, the primary military sidearm is called a Stinger. It's essentially a hand-held rail gun that fires a 10-grain projectile at extreme velocities. I've researched the size of a grain, and the only thing I can figure is that a 10-grain projectile is roughly the size of the projectile for a pellet gun.

The key here is that the gun fires the projectile at such high velocity that being hit with one at close range is like taking a grenade at point blank range, and the size of the projectile means that the weapon is capable of carrying a large ammunition supply (a shoulder arm Stinger carries 1,000 rounds fully loaded). The only drawback would be the lack of a stun setting. Here's a my on-the-fly stat conversion:

Name: Drake Armaments SKE-33
Type: Personal Firearm
Scale: Character
Skill: Firearms
Auto Fire: 2D
Range: 3-50/100/300
Damage: 6D @ Point Blank, 5D @ Short, 4D @ Medium, 3D @ Long
Ammunition: 1,000 (fired in bursts of 10 rounds on Auto Fire)

I have an NPC that uses a railgun anti-materiel rifle. It fires a small caliber projectile at a little more than 5,000 feet per second. No grenade-like blasts, but he also doesn't have plasma trails from surface heating giving away his position.

Mine isn't really a grenade blast either, just a small projectile that inflicts massive damage from pure kinetic impact. In Redliners, atmospheric interference degrades the effectiveness of stinger projectiles the further out you get, so that while they would splatter a human target at point blank range, at longer ranges they do little more than a good punch, and the soldiers have to compensate by using hand-held rockets for long range work. Larger vehicles come equipped with "coil-guns" that operate on the same principle as stingers, only with larger rounds.

Id say that gun would have one hell of a recoil!!

Mine sure does. It weighs 30+ Kg for a reason!

Coil guns or stingers? The only coil gun seen in use was turret mounted on an APC, and going strictly off memory, I don't recall whether stingers had much of a kick (although some other weapons in the story kicked like a mule on steroids).

The stinger sounds a bit weird. Grain-sized projectiles sound like a shotgun
Either the projectile is aerodynamic to reach those high velocities without spinning. But an aerodynamic projectile with such a high velocity will have some difficulties to "apply" the kinetic energy to its target, without just passing through the target.
Or it has some kind of a flat nose (like HP ammo) to inflict damage. But then it won't travel that far because the projectile will start to spin and then anything can happen.
All in all an autofire burst of 10 rounds (10 rounds out of 1000 equals by the way the 100 rounds of a blasterrifle, which is quite high, as mentioned earlier in this thread) wouldn't inflict much damage.

Besides micrometeoroids came to my mind. They are small, have extremly high velocities and even a space suit offers some protection for persons.

IIR, it was a actually a type of Gauss Gun rather than a railgun.


Aren't the two basically the same thing?

Nope.

A Gauss Gun uses magnetic coils to accelerate a projectile like a maglev train.

A Railgun uses two electrically charged rails and a conductive projectile...

Ah. Learn something new everyday. IIRC, the stingers were actually Gauss guns.

Powerguns are also pretty cool and they look/act a bit more like a sci-fi ray gun or blaster. http://en.wikipedia.org/wiki/Hammerverse

one of my favorite weapons of Sci-fi has always been the Gauss/Rail rifle - it fires a bullet at supersonic speeds using magnetic coils to propel the bullet - the only gamesystem in ever saw it in was GURPS Ultratech, which btw is a great source of inspiration for weapons.
