Just started Shot shell loading a couple years ago, mostly hunting loads for my Drillings with #2 and BB for coyotes. I have used the !6ga Manual, and the Advantages Manual. I do have to adjust the stack hights sometimes, with blackeyed peas and/or fillers and overshot wads, especially with the BB. I use Precision Reloading quite a bit, also Hodgdon, and Alliant powder companies, I got one of my best 2 1/2 " squirrei loads from one of them. B&P also has some free downloads, from "The Curmudgeon" . He had some pheasant loads listed. I use Unique, Longshot, Universal, and 800X , Fiocchi and Cheddite, hulls and primers mostly. I'm not a big clays shooter, so I mostly do a box here and there.
