Railgun better than a Laser Cannon?

[willg]

This thread reminded me of a weapon I dreamed up way back when I was playing Doom 2 with a software patch. Essentially it made the pump action shotgun into an.automatic, did not have to reload it was prety much. Booboobooboobooboom. Phenomenal firepower. And I recall coming up with an in game rationalisation for this , it was a railgun/ shotgun hybrid. The shotgun would fire and the magnetic fields would catch the metallic shot and boost it to a much higher velocity, increasing the range and kill zone for the shotgun.

One of the things I do enjoy on SWRPG is the exotic weaponry. I recently came across the E-11 / slugthrower hybrid and after adding a few mods, have made it my main weapon of choice. This allows sound suppresors and speciality slugs to be used, ie explosive, incideary, poison etc. But the only shotgun I came acrosd was qn 8
Guage.

Even as a hypothetical weapon, anyone care to stat out a ShotRailgun?

Edit- turns out theres some real life development in this field, even in discussion.

Imagine a double barreled shotgun with one barrel holding buckshot and the other holds a slug. The Ion rail-gun round fires a cluster if Ion Discharge type grenades or warheads to disrupt the targeted vessels shields for the following armor piercing solid slug

sounds workable to me
