I use this type of stand now, as i don't have to tell my buddies to keep their bullets on the target. Buddies have a way of always hitting the pvc pipe. Now I just throw the targets on and have at it...:
I don't have any buddies, so damage will be all me.......
Because these are going to be left outside 24/7, I originally was going to build them out of treated wood, but decided on the PVC route instead.
These have 3 literally 1000's & 1000's of shots at and through them. They were built using the galvanized frame from furnace filters. The 2 on the ends had the top piece on each wore to a frazzle till they broke in half & I took them off.
