The range where I usually shoot (my buddy is a memmer, but I'm not, but he brings me as a "guest"---saves me membership dues!) says no rapid fire.
When we inquired as to exactly what "rapid fire" was we were told, "basically one shot per second". We've exceeded it (but it was still aimed fire, re-acquiring the target between shots) and never been given a hard time, but we often shoot on weekdays when the isn't an RO on duty, and often no one else shooting.
If I wanna play with "bump fire" (can't seem to get the hang of it) of really rapid shooting I shoot out back in my woods...Just there's alot of brush and junk, so we go to the range to fire at known distances, and fire off a solid rest (bench).
