I usually hunt with a 3"-Hevi-13/#7 in the chamber and two Hevi-13/#6's in the magazine tube. Last season, I worked an old gobbler for about 30 minutes, gave him the "silent treatment" and had him slip in to about 30 yards. When I shot it, the recoil literally stunned me, and when I got to the gobbler the devastation to the head and neck further stunned me. It was only sometime later that I realized that I had shot the bird w/ a 3" MagBlend instead of my usual 7's. I've killed a bunch of gobblers w/ the MagBlends and wouldn't hesitate to hunt w/ them in several of my guns which pattern them exceptionally well. With that said, all of my MagBlends in both 3" and 31/2" are of the "old" lot numbers which I stocked up on based on their performance in my shotguns. I'm "old school" in that I've seen too many instances where a manufacturer either messes up a "good thing" or discontinues it, so when when I find something which works for me I always buy two or stock up.
