I stuff my Ames with plastic wrap I dumpster dove for behind a furniture store. It's the heavy plastic furniture comes wrapped in. Been using the same plastic for 8-10 years! On my second bag target in that same time frame. It takes a lot to shoot them up! I recently bought a couple additional faces to use at our local county range. The range is a soon to be 14 target covered hay bale work through course open to the public. Soon to be, as soon as the local Boy Scout Troop in the area finish! Carry my Waldrop pac seat with 2 burlap target faces and I'm set for a couple hours of 3d shooting, or should I say 2d? Love Ames targets.
