I had to go digging for a 28lb S&F Practice Death Weapon at Wainfleet a few years ago. The impact point was scored as 20ft at 6 o'clock... On the range tower.
It had been launched from a 'toss-profile' by a RAFG Tonka, allegedly.
The tower is/was located some some 1.5 miles from the intended target area which was a mile out in the Wash past the sea-bank. In those days the tower was located in the SW corner of the range compound, not as is shown now on gargle-earth in the NW corner.
Tonka was ordered off the range; the Death Weapon was never located...
