i load my 12 and 10 gage both the same as store bought loads show , small game i use a 20 ga load in both for cotton tail or squirrel for trap 1 and 11/8 oz and 11/4 and 11/2 in the 10 ga for duck or turkey best part about a ML shotgun you can load for what you want dosnt hurt a thing to shoot a 20 ga load in a 10 gage get good pattern to . I like fffg powder best in shotguns, I like mod choke barrels for ML or mod screw in chokes seems it dosnt tear up the wads as bad when loading
