A lot of people want to justify loosey shooting rifles by claiming they are minute of "bad guy" accurate. Ie, they can hit a man sized target at, say, 100 yards. I think this is a myth. For a civilian, accuracy is important. Minute of "bad guy" is not good enough.
Once the shooting starts, no one will stand out in the open. All you will have is a head, foot, leg, ect.. to shoot at. Accuracy will matter because even the small targets won't be there forever. On a related topic, the more cover your rifle can penetrate the better. Since the bad guys will be hiding behind things, better penetration effectively makes your target bigger.
In a SHTF scenario, you will probably will not have a team to lay down a volume of fire. You will need as many first round hits as possible. First round hits mean you will expose yourself less and live longer.
