One Holer,
He was a very lucky man indeed at that range, if you consider that Sniper Schools were in their infancy! He may of course allude to that in a book, but practically speaking when you are next on the range with a MK1 anything scoped up, try it yourself.
He must have had calm days, no wind and a bergen full of luck. It is absolutely true that in WW2 snipers were told to take their "maximum kill" shot at 400 metres, McBride clearly didn't go to kill, he must have wounded a lot of men![]()
