While there's a real difference in shot size with the Federal shells, it's not the shells that are causing your misses.
Any of these promo loads are perfectly adequate for most shooter's abilities.

And for folks like me and probably a whole lot of others who don't shoot competitively, price is the most important factor. I'm nowhere good enough to ever determine that Win AA loads will break more clays than Universals.

If I get hooked and start getting serious about competing in matches, then info like this becomes more useful and might be more relevant.

Seems to me this is like the silly games truck makers do with their ads - our truck has 3.267 more HP and 6.132 more ft-lbs of torque than the other guy....not that it will ever make any difference in your life, but it might make us a few bucks if you buy our truck instead of theirs because of those numbers.
