Has anyone ever tried a 4 leg front rest base? Instead of the normal configuration triangle base I am thinking more along the lines of a diamond shape. I ask this because when I am really trying to shoot my heavy gun fast I sometimes make the rear rest leg bounce just a little. Is 4 contact points on the base even legal in Ibs 1000yd Br. My front rest is pretty heavy, if I am just shooting I never notice the problem, it is when I am really hammering them down range for record target.
