[@6slyboy6] No problem, I just wanted to make sure you had the relationship between the factions straight. The Concord worlds and the Exile worlds are situated within Collective space. The Concord worlds just have free access to that space because they're engaged in a co-operative relationship with the Collective.

In regards to coilguns, they're more or less stealth weapons. That means the projectiles usually travel subsonically in order to not generate any noise. They can be switched to supersonic modes, but even in that case they're still beat out by propellant weapons (over distance), because this universe's propellant weapons are essentially rocket-bullets, and continue accelerating as they fly through the air.
