My next door neighbor (actually a mile away), a young, single farmer, loves shooting long range. He has a moveable gong about 30" diameter sitting at 600 yards. from his front door. He bought the farm next to me and moved into the old farmhouse, remodeling it to his own satisfaction. When the crops are harvested he moves the gong to 1000 yds. I hear him late on a calm afternoon shooting and ride over occasionally. He uses bipods on his long range rifles, which are built on chassis and are all metal. He opens his front door, lies prone on a rug in the front room, and shoots out the front door. Some of his 600 and 1000 yd. groups are amazing. Biggest thing he's got is a .338 Lapua.
