I'm proud to say that I have shot a stone - roughly the size of a brick - at a lasered and witnessed range of 301 yards with an air rifle. The first couple of shots missed, but kicked up dust in the muddy field, so I could see how to adjust the aim. Once I'd worked out the aim I managed to hit it two or three times in a row before some close misses. The rifle was a regulated prototype, set to 60 fpe and firing Eley Magnums.
