I said the same thing as Stankard... Hmmmmmm! Might just be worth a shot (pun intended!).
I get it from Hobby Lobby.I started out using old clothing and towels like most others here. I found this material a while back and have put almost 100,000 shots at it with 3/8 steel. Most other fabrics lasted me 1 day, sometimes 2 before I wore a hole in it big enough to allow my ammo to pass through. I shoot around 300 shots a day. Long story short, the first time I ordered this mesh it was a game-changer, I no longer had to worry about changing my backstop. I'm pretty miffed they changed it and I hope I can find more like the original.I'm fairly new to this but have tried a lot of different materials (had a huge bag from a second hand clothing store to work with) and have been using a piece of double nit fabric from the back of an old blouse. I have well over 1000 shots at it using 3/8" steel and it is showing very little wear. I am finding the lighter the material and hanging as free as possible works the best to stop bounce outs.
