I just got off the phone with that new girl they have over there. The bottom line is, I don't think they are going to load any 6/7's. Not for me anyway. I had ordered some 3" a couple of weeks back, and they patterned great. So, I think I am going to try the 3.5" 2-1/4 oz megas.
Here is the pellet count per oz
4= 118
5= 132
6= 201
7= 272
