The unaided human eye can resolve objects of about 1 inch size at 100 yards, which would make a one power scope suitable for consistently shooting one MOA or better.
A six power scope should provide resolution of objects of about one sixth of an inch at 100 yards, giving a potential consistent group size of 1/6 MOA, or .17 inches or better at 100 yards. IF the shooter, rifle and ammunition are up to the job.
