The no double tap rule is good in many cases. Where I live there is an indoor 18 yd. (Yeah, I know it's really small, owner is a great guy). Our local 50yd indoor range went under.
The ceiling is covered in bullet holes. The side walls are also well scathed. I realize that practice makes perfect, but when you can't control your firearm at all you may want to start small and work your way up, caliber wise, not as in shooting the ceiling or light fixtures.
Yep, those are all rapid fire, new shooter, and poor trigger control holes.
Our 100-Yard range is covered in bullet strikes. Granted, beyond 40 yards, the pistol rounds have a habit of skipping into the ceiling.
