In my world a clip is 5 to 10 rounds held together by a metal "clip" ah la the old M1 Garand or the 303 5 round clips.
Something that holds several rounds is a magazine. Mags are what go on you hot rod's wheels.
In terms of time scale I'd look less at straight out over ground speed and more at time taken to execute an attack.
A game of 40k is around about a platoon attack so I'd say the whole game is at least an hour of real time.
