Yep, a rock solid rest!  Or do you mean the nice new bench ODNR built for me that's in the background?  Someone got tired of the old shaky one and tore it out of the ground.  You just gotta love the poor boy equipment, those are corn bags from northern Indiana, I used to be a member at a 1000yd range up that way, Young's Longshot.  Found the place by accident when I was out cruising on my scooter one day.  I knew what the wind flags out in the middle of all that corn were!
