Winchester makes some LR AA Loads. They have 26? grams of shot. There are a lot of LR buck shot loads out, I think every body makes some. The one that comes to mind is a federal tactical, #4 buck 27 pellets lead not plated, not sure of the speed. I think they even make LR slugs, If you have the oppurtunity, and situation to shoot them for HD. The size of the shot has absolutely nothing to do with recoil, it is the weight of the pellet, wad, and powder, velocity, and weight of gun. 1 1/4oz of buck kicks as hard as 1 1/4 oz of 8's all other factors being equal.
