Just wondering if anyone has ever made their own archery target, and if so what did you use and how did they last? I have tried layered cardboard and a feed bag full of plastic pieces, but neither of these held up very long. I was looking at rigid foam insulation the other night and thought that might work if I layered it back to back. I also have a pile of marine styrofoam laying around and I know that will blow into pieces in no time, but I thought about wrapping it in multiple feed bags? I figure this won't last very long though. Anyways, looking for opinions/ideas on what has worked for others. I am shooting a 70lb bow and the arrows like to run to the fletchings even at the range.
