hi buddy
i find pigeons a bit tricky too, to shoot as i mainly shoot bunnys.
but here is a tip if your sitting in wait for them,then let them settle and once there head sinks in to its body,but still visible.then this is when they are most relaxed,then THWACK! them,i got 2 over the week end as i had spike25blue down, and i was teaching him how to shoot them lol
regards
