Forgot...I also covered the surface of the backstop with white roll paper. Then I can use Shoot-N-C peel & stick targets. Any other 8-1/2x11" printed targets I use can simply be stapled to the backstop. Me dranks all da wine...(HIC) and that's how I messed up all the meazurmunts of the rifle rax and had to use...dim for a target standdddz......(HIC)....
Ok then...what if I attached my 4'x4'x3/4" half-sheet of plywood to my cedar fence, and then screwed on a pair of rubber auto or truck floor mats to the front surface, then taped or pinned my paper target to the rubber?HAL
Car floor mats are not going to stop a pellet much. What Gene was talking about is the flaps on the outside of 18 wheelers that keep mud and rocks from being thrown from the tires and hitting the car behind it.
