A lot of it also has to do with lighting. A buddy of mine and I did a lot of photography at the range once. We used different lighting, different ammo, slow-speed, fast-speed. We were able to capture a lot of cool stuff. There was a lot of sparks emitted. With less light, they are more prominent. Digital photos and video capture stuff that the human eye doesn't necessarily see.
apparantly can happen, depends on type of ammo, cleanliness of the barrel, any jagged edges inside barrel etc
