So I decided to mess around with my pneumatic a bit today:
I decided to load up a metal bolt I found, since the light capacitors I was firing before just weren't cutting it (plus I was wasting perfectly good caps).
I spot a small box of logs to shoot at, charge up my cannon, and take careful aim.
Well apparently it wasn't careful enough, the bolt punched one of the corners of the box and proceeded to embed itself in the cement wall behind it.
Now I honestly couldn't have made a cleaner hole with anything short of a hammer drill, and it appears that the box had no impact on the orientation of this bolt whatsoever.
I'd have taken pictures, but I didn't want visual proof of this. If ask real nice, I may just post some up:D
