Yes the XR #6's shreds a target, but can they kill a bird. I patterned them in a SBE, SBE II, and Browning Gold all with remarkable patterns at 40 yds. Problem was I found shot stuck in the paper plates each time. I removed the plate and found TONS of shot stuck in the surface of the plywood I stapled the plate to. Must not of had much energy! On the other hand, my Nitro 51013 4 x 5 x 7, a little better pattern, plus the 4's blew through the plate and 1/2 inch plywood. That'll kill a bird!
