I took 6 today, and two "pass through doubles". I really shouldn't do that, and especially now. Still, I killed all birds so I'm happy. And it's pretty exciting.
But these guys are tough.
On one of the doubles, I killed one on the spot, but one ran. He presented me with a shot as he hid under the wheel barrow, and that was that. The other double, flipped both birds up and over. I thought, "this is too good to be true", and sure enough one gets up and runs. He stops under the feeder~20 yrds, and I pop him again and he lays still.
I glass the first bird, and the darned thing is sitting up! So, I pop him again. No further movement. Good. I go back t work, but think, I had better check on things one more time. Sure as heck, the second bird has moved. I follow his path in the 5" of snow and find him hiding half behind my target wine box. It's cardbord, so I put two pellets through it and saw no further movement. It took three/four solid shots to put that bird down. So, I get ready to get back to work, and that first bird is sitting back up again. Bear in mind that I saw blood behind him on the second shot at him. I got him center mass from the side. Now he's moving again, trying to flap his wings and jump up. I'm not sure what was pumping in his veins but there wasn't much blood. I bead in on him again and take him high on the body and that's that.
But that's 2 birds today that have taken 3 shots to kill. Tough.
(again, Crow Mags through a BC1200).
