Used for shooting in the back position which is often used in target shooting past 1,000 yards. Konor will perhaps know the Glen Tilt range on the Atholl Estate in Scotland no doubt. I think that goes back to 1,200 yards although I have only shot it back to 1,000. Only range I know of where shooting is suspended to let deer across or if low flying aircraft come screaming down the Glen. Great spot! Lagopus…..
