Been using a table I built my wife down at our cabin to shoot off of. When I want to shoot out to 300 yds I have to load it up on a trailer and haul it down to my deer club and shoot. Found this article with video and think this may be the ticket. Might make it wider to accommodate right and left shooters. Rick
