Thought I'd post a picture of my shooting bench. I made a wood form and poured the bench top out of concrete. It's got rebar in it to reinforce the top and also tie the legs in. They are welded to 1/4" thick plates that were put into the bottom of the form. It sits on three concrete pillars. Around that I made a 10' square patio out of local creek rocks. The 4 corners have concrete pillars on footers that I plan to build a roof over next year sometime.
