What some people need to realise about long range shooting is that it's only meaningful if you have a reasonable degree of control over where the pellet or bullet strikes. There are cut-off points, depending on range and equipment where the whole exercise degenerates into a game of chance. Eventually you may as well be rolling 5 dice to see how long it takes for them all to come up sixes.

I politely asked Harry to tell us about his methods for reading the wind and applying corrections ( before I came to the conclusion he was full of it ) and he didn't choose to reply. Not because he was banned either, he had enough time to write a number of long rambling posts in the meantime, while ignoring the question.
