Hope the guy running the trap was OK, cause he sure as ..... wasn't shooting the pidge!
Whatever is at the end of the barrel looks metallic. There is no blur, so I assume it is not the projectile.
What type of camera would be necessary to freeze the action of a shotgun discharge to capture the projectile? Shutter speed?
In a very controlled enviornment that is possible. This is outdoors and appears adhoc.
