You've got a nice collection there.
With all the bullet holes (right over your head) in the ceiling I'm not sure I'd feel safe shooting there - holy cow!
I'm an RSO at a local club and our indoor range's ceiling was being peppered by recent gunshot (nothing like the photo). We determined that some of the damage was caused by people shooting the Taurus Judge revolver. However most of the damage was being caused by...a range officer practicing his quick draw.
