Whether bullets (solid projectiles) work depends a lot on how you envision those projectiles. But let's recall that the "lasers" on Star Wars and BG didn't really look and act like lasers. They are more like miniature photon torpedoes. Definitely slow-moving projectiles, not (almost) instantaneous beams. So our discussion is really only about whether the projectiles are solid mass or bundles of energy. I like the physics of solid mass better.
I don't have time right now, but later I will fish out, copy, and repost my earlier argument in favor of bullets.
