I've been researching a little on them. There is not a whole ton of real world data on them, but from what i have seen they are patterning pretty well for a lead shell with a meager payload.. With this being said do not know if it justifys the price..
If I were setting a gun up strictly for the use of lead, I would look at the Wal-Mart Exclusive Federal Turkey Thug in a 3 or 3.5 inch 6.. They are tearing the patterning board up with some of the best lead patterns ever seen.
I have called every Wal-Mart within an hour and cannot find 6s..

So I am going to have a member from another board send me some.. They only run 10 bucks, less than half of the white lightning load.
