That makes sense, though unlikely. But yeah, I guess there a few inexperienced idiots who ruin it for everyone. The only time Ive hit the ceiling (or so I thought I did) was a couple times when I was shooting my Beretta 96, and my finger pressed the trigger directly after an aimed shot, and the gun was still pointed upwards because of the recoil. Kind of scared me a little. I was expecting to shoot, but the shot came too early, and I think I might have put a hole in their ceiling
Ah well though. Apparantly im not the first
