I bought a second target to add to my 3 D target range today and built a nice stainless frame to serve as a backstop to catch arrows that miss a target. (I was shooting at 50 yards so give me a break) I got my hands on some HDPE landfill liner material. I figured it would hold an arrow back at that distance, nope I had an arrow go thru. It was just on the other side I had no problem finding the arrow. I just don't want to tear flechings off . Is there a better material to use like landscape fabric? The backstop is 5x5 approx.
