Those look good, but I have seen on threads in other forums where the all copper slug didn't expand. I have seen them on the berm of shooting ranges still almost completely in the same configuration as loaded, probably at the longer ranges, also (OP). There are a number of shooters that kill deer with them though. My comments weren't directly considering the (name brand) ammo but the firearms for witch the possible ammo could be shot more accurately. I have shot decent groups with SSTs, Rem 385 gr sabots, and the Fed powr shok sabot, though. Have you ever though of an accurizing kit for your pumps? Check out the Manufacturers forum.
