with the anti matter guns, this is how i see them working.
they take lots of energy, and convert it into antimatter using something. possibly gravity wells.(more or less localized miniture black holes.) and then hold it until its needed in magnetic holding fields made possible by superconducters.
when the fire command is given, the magnetic fields act as a coil gun. accelerating
the glob of anti matter to speeds needed for hitting anything. the glob of anti matter gains a layer of energy from the annhilation with the local steller meduim, keeping it from exploding.
and forgive my spelling will you, its one in the mourning.
