If you are planning to limit your shots to 100 yards, a load of 70 to 80 grainsshould work wonderful. And not kick all that much either. I noticed the 410 Hornady starts to open up groups at charges beyond 100 grains. With the MMP sub base, I was able to maintain good groupings with 120 grains of 2F T7, as well as 130 grains of Pyrodex. I'm not particularly recoil sensitive; but I still prefer to do all myMZ range testing from the Caldwell Lead Sled. One or two shots per year on game under field conditions is all I really want to shoot loads at this recoil level.
