Thanks Fish...so I shotgun eh...well, I will see if I can get one. Birdshot too small you think, or would a slug take them down better? Talking about horse flies (deer flies, bulldogs...etc), I was working on a Bell 212 in northern Manitoba, it was at idle and the blades spinning, I was hearing a thwacking noise, looked down in the grass and it was horse flies, they were hitting the spinning blades and falling like...flies??? Lol. The worse thing was, these guys would just shrug it off and fly away...I have seen trees taken apart with rotor blades. You know, come to think of it, a shotgun might not be big enough :)
