YES SHADE.

Accept that you can use either a coil gun/mass accelerator or a rail gun for the same purpose.
Now, a railgun is a form of a specific mass driver, but it's still a mass driver/mass accelerator, sorry to point that out.
As far as i remember the maxim definition, it said it behaved like a mass driver, but no one could conclude it was one, plus it mentioned the fact of conventional explosives once, also the fact that it had a smoothbore barrel on the maxim, you can't conclude it's a railgun.
There was enough of the definition to speculate whether it was a coilgun or not which is a mass driver/mass accelerator just like a railgun is.
But, it's really not even that, the maxim just appears to be a gun that uses conventional explosives to drive bullets(probably uses caseless bullets at that, or you'd see bullet shells after firing the maxim).
The fact that it's a kinetic weapon in fs2, and it said it behaves like a mass driver was why i thought it was worth mentioning(the fact that it may have been in any way similar to a railgun).
I have built a coilgun before.
The reason i went with a coilgun was because i found it easier to build.
They both use different methods of propelling a slug, but they can achieve the same velocities, and both take advantage of electromagnetic forces for propulsion.
It really wouldn't matter which way you went when building an electromagnetic gun.
Plus i find these two types of guns too related in the fact, that they both do the same thing.
It does not take power from half the US to run these things, it takes usually about the power provided from something the size of about a city block.
Which would like just say, plug a powerplant into it.
The smallest powersource i've read about for a railgun was something the size of a van.
I mean, people are considering putting these things on carriers and stuff, if testing proves the railgun worthy, maintaining the rails on such a gun sounded like ***** though.
