I recently got a 22 caliber target in the mail. I purchased it off of Amazon.com for a whopping $14. It is rated for 22LR only, saying the minimum distance for a pistol is 30 yards and minimum distance for a rifle is 100 yards.
I ran across one of these while shooting at The Cove in Gore, VA. Someone likely left it there by accident. The target was great for 22s, but it would keep falling down. The ground at that shooting range was too hard to get the target to go into the ground. When I used my feet to try and push the target into the ground, I wound up breaking one of the welds. I decided I needed one for myself, and at only $14, it was mine.
I had to make a base for it while all of its legs were still in good shape. I knew if I took it out and tried it at an outdoor shooting range, that the legs would be bent in no time. I used a piece of scrap wood and cut two lengths of 16 inches each. I used some of the remaining wood to make crossbars, keeping the two 16 inch lengths parallel. I fastened it all together with plates and philips head screws. I pre-drilled to keep from splitting the wood.
This should work out just fine. I already had the materials, so this quick project only cost me my time. The base that I made is rather thin, so it won't take up much space in the trunk on my next trip to the range. I'm keeping the box that the target came in for ease of transport.
