I have the Supermag as my dedicated turkey gun. I scoped it and put a Gobblin Thunder choke tube in it. The 3 1/2s kill on both ends, no doubt about it. If I had it to do over again, I would get a regular 870 express, but the mag will work fine. I really like the gun, but most things that walk can be killed with a 2 3/4 inch shell.
