I have found I can't shoot repeatable groups without a bench that absolutely won't move with the shot. I had to make the top with 2 layers of 3/4 inch plywood, then ended up with 2 inch pipe on all 3 legs. Even after all this I had to brace between the legs. What do you guys use? Anyone have plans for a stable folding type for portability? Needless to say mine is heavy and not very portable!
