Ineffable, kudos at your good sense of humor. I don't think JP meant anything serious by it - but the thread direction has taken a bit of a turn that isn't normal.... LOL
If you want to get a weapon platform, capable of the longer range, Zombie stopping type of hits you seem to be describing, none of these is a great choice for you.
Could they be made to work? Yes. Are they ideal? No.
550 yards is a long ways brother. 5 football fields if you think about it, just about endzone out of bounds to endzone out of bounds.
Should SHTF, do you have 500 plus yards of open field within your free fire zone around your place? If you do, then I suppose it's a valid concern.
If you walked into the shop with the same criteria, none of the weapons listed would be the direction we would point you towards. For what it's worth...

PS - Every house should have a good quality boltgun in it. They are just so useful for all sorts of things.
