I must be lazy, I just took my tractor when the back hoe was on it and dug into the side of a big sand loam hill till I had it square and put a couple of big PVC tubes in the ground with caps on the botton and made a target frame so the legs would go in the PVC when I wanted to shoot, when I want to shoot I just put the frame on the ATV load my stuff and drive the 1/2 ile or so to the other side of my property. I gave an old wood ironing board a bit of modification and us it as a bench rest. Lee
