Okay. So I'm not really an expert shotgunner by any means. Most of my experience is with rifles and a little bit of handguns (incedentally, of the guns in my sig, the 870 is the only one that's mine). But I always see people writing on forums saying they think buckshot kicks harder. I've shot 7.5 shot at 1250 fps and some slugs at 1610FPS (factory ratings). Both were 1 oz. I have to say the the slugs totally kicked harder, but not that bad. But I specifically went after full power loads. I'm sure if it was a reduced recoil slug, I wouldn't have been able to tell a difference (even if there were one). I guess my real question here is, will two loads of the same weight and velocity recoil the same, or nearly so, or is there actually a difference? A simple physics education such as I have would suggest the difference would be minimal at best. Shot being debatably "softer" since there's more projectiles to get moving.
