Since I only own SxS's, that's what I use for target shooting as well as hunting. For the comfort of my old shoulders, I've dropped down from 1 oz. loads to the 7/8 oz. ones in 12 ga. Much more comfortable and they work great. My 12 ga. guns range from 5 lb. 12 oz. to 6 1/2 shooting sporting clays and the occasional SxS meets.
