A method and apparatus for trapping projectiles so that the projectiles are not damaged is disclosed. An elongated trough is typically filled with alternating layers of a foam substance and a fibrous substance. Alternatively, the trough can be filled with just a foam or fibrous substance. A projectile launcher such as a gun is connected to the trough and a projectile is shot into the filling substance substantially parallel a longitudinal axis of the trough. The trough can be opened and the projectile can be recovered from the filling substance.
