I'm in the process if building a new front rest, and wanted to get it lighter than my current set up. My current set up has a windage bottom and weighs in at 32lbs. It very stable and works flawless for my 17lb light gun. But, I would like to have a light weight version for my 10.5 lb 100/200 yd gun. So, the question is: What do you think the minimum weight should be for stability, and what size of footprint? Most rests I have measured have the feet arranged in a 7' radius from the center post.
