I did a test between federal 00, federal 000 and some wal mart remington 3" 00. I tested at about 15 feet. The pattern from the federal 00 was really tight... Around 3" very tight pattern at that range. The federal 000 yielded a 5" pattern. The 3" magnum Remington yielded a much larger 10" pattern. I'm more comfortable with that size pattern at close range. I suspect that as the more "premium" brand, Federal has gone to great lengths to make their rounds pattern tighter. This makes them more useful over realistic hunting distances.
In reality any one of these would be a really bad day for the recipient if even half the pellets are on target. I have no experience with the lighter weight shot. I'd say get some and test it for pattern and penetration.
