Not with an air gun but have with a shotgun!
Was beating on our local shoot, last drive was the 'home wood' where birds went out over a low meadow.
There were some Hungarian guests who shot at anything.
Near the end of the drive a couple birds went out low, we saw the gun take aim and had time to turn round!
Both barrels straight at us, got peppered with shot which bounced off my Barbour!
Thankfully we were far enough away for it not to penetrate.
Did give the 'guest' a polite mouthfull after though
