Why have the wind at your back when pigeon shooting?
Pigeon shooting
PETER THEOBALD
Simple aerodynamics dictate that all birds try to land head-on to wind, which means they will present the easiest shot if they approach your pattern head on.
They will commit much more confidently in this situation, as they can slow right down prior to landing, giving them plenty of time and space to exit quickly if they spot danger.
If things go to plan, you should be able to kill the first bird before it sees you, but still have time to complete a right and left as the survivors veer away.
