I can verify the blends having pellets smaller than 9s in them. After the above mentioned turkey finally got dead, I examined him. I couldn't figure out how he would drop and get right back up, so I skinned his head out. Found nearly a dozen pellets lodged between the skin and skull -- all of them tiny. The shells looked great on paper, but those tiny pellets are more than worthless much past 30 yards. They'll make holes in paper, but not a turkey skull.
After that I swore off the magblends, cut open a few that I had left, and discovered that they are NOT 5x6x7 -- they are every imaginable size and shape. Some round, some oblong, some stuck together in clusters, some stuck together making snowman shaped pellets, some (several) that were smaller than I would shoot at doves.
If I were going to shoot hevi, I would shoot straight 6s. They won't be super consistent in pellet size either, but they'll be better than blends.
Some of you may have seen this before, but take a look at these charts -- I found them very helpful. Hawglips (the author of this thread) is actually a member here, but he is really active on this other forum. He has tested and forgotten more about turkey shells and patterning than I could ever learn.
