I also been using compressed straw bales from tractor supply. Here, they run $11 each. The bands go around the outside, so no danger of hitting them and busting the bale. The things weight 50lbs, and are slightly bigger then the biggest block targets. You do need to get them off the ground, and use a tarp or some other protection to make them last. Any target wears out, but if you shoot a lot, it gets costly. With the compressed bale, i might go through 2 a year, maybe 3 tops....thats $33 a year max....cant be beat for as nice as they are. I leave mine in the bag they come in to provide more protection.
