who uses them? What do you use?
I found out that a big round hay bale works great for shooting, so I've got a bunch of archery targets. I go around the hay field shooting round bales at all different ranges and elevations. Now I want to pin on cardboard or paper animal silhouettes to pin on the hay bales.
Just gotta make sure you shoot the round face of the bale and not the open ends, and make sure you shoot well in from the edges.
