If your Turkey hunting it shouldn't matter. You should only need one shot unless your shooting a .410 and miss by a little.
And what if you miss by a lot with a 12 gauge or 20 ga. and what if you have more than one turkey come in and you want to kill them both.
I'm sorry, but for me personally there's not much of an excuse for missing an animal that large at such close distance with a scatter gun. If you do miss it's probably because you haven't spent enough time shooting the gun, either not testing enough different loads to know how your shot is going to fly, or just not being adequately comfortable with the firearm which would indicate you likely have no idea how the shot is going to fly at different distances.
I know I differ from many others but I don't care to harvest more than one animal at a time unless it's a non-game/nuisance animal.
To each, their own
