Nope. Flying into a headwind, practically hanging in the sky above me. Damn near the same thing happened last Night. I managed to knock down two Mallards. First one came down like a brick. Second one left me cussing. A flock came in, again into the wind moving slow. Most were hens, the second last one was a drake. I came up, put my bead just in front and proceeded to miss. I fired the second shot and he did (I'm serious) three foward rolls as he came down, came out of the roll, opened his wings and glided straight down and to the left of the incoming wind. Once he picked up enough speed, he leveled off, meanwhile I'm now running towards him thinking he'll give up the ghost and I didn't want to lose him in the tall grass. Instead he started to flap and gain altitude, now out of range he flew off like nothing happened. I swear I just knocked the wind out of him. These are BlackCloud BB shot. I've had good luck with them, but bad luck, too. I never detected a softer report, but the wind was blowing pretty good in my ears. I figure there were some bad, soft loaded shells in that box. It looked like somthing you'd see in a cartoon, no word of a lie!
