En.wikipedia.org/wiki/vacuum_engineering is quite an interesting read, although I dont give merit into introducing vacuum into the consumer market I do think it may warrant testing with theoretical maximum velocities. I was not aware particle accelerators make use of ultrahigh vacuum systems to achieve their velocities.

The Myth Busters TV show did a segment on a ping pong ball shooting air powered AG and in their experiment they were able to achieve improved velocities with with a vacuum in their barrel. I don't know if that would make a major difference with a more aerodynamic projectile.
On the Myth Busters segment they only measured the projectile speed after it exited the barrel
