I've made a few different versions
first one was just hanging from the bottom of my rifle target stand, but the splash from the bullet shredded the wood real quick
second one I made from galvanized water pipe. that one is still going after a few years of use.
these are my latest. 1st one is from ebay for about $60 not including chain and targets. targets are 10"x1/2" and 6"x1/2"
second one is made with 2x4's and bracket from ebay. brackets were about 20 and wood is all 4 foot lengths. targets are 3, 4, 5, and 6" x 1/4". this will be for pistol use
