Just picked up on this one as computer has been down. Someone asked about hearing the shot at that distance. I used to shoot full bore rifle in competition using the 7.62mm. Long range comp. was at 900 then 1,000 yards. On a normal day that round goes subsonic somewhere between those distances and can make a real mess of the score due to its instability as it goes back through the sound barrier. On one occasion I was in the target butts when someone had a go with an old 577/450 Martini Henry. We would here on the radio, 'he's fired' then a muffled boom then a 'Zizzing' sound as the tumbling bullet passed over. He never did hit the target.

Good books on sniping; 'Sniping in France' Maj. Hesketh Pritchard. 'Out of Nowhere' Martin Pegler and 'Sniping in the Great War' by the same author. All highly recommended. Lagopus.....
