Mean is a good word to describe it, Ted. I've always "enjoyed" shooting heavy recoiling chamberings, once or twice, for effect. But, there was no fun in shooting that thing.
I used to compete with a .54 cal. roundball rifle, and at 100 yds used a stout charge of 85 grs. FFg. I once let my attention drift away, while loading it at the bench, to a conversation going on between others. Long story short is that, it became a comedy of errors as I became confused about how much powder I had put it, and turned it upside down in an effort to dislodge and dump all I had put in. I only saw a couple grains fall out so assumed It was empty and ........ dumped in another 85. Somehow, through my carelessness and inattention, I ended up with well over 200 grs. behind the ball. When I touched it off from the offhand position, it nearly jumped out of my hands, and the aperture sight on the wrist hit me over the eye and drew blood. But even that did not rock me like that Mossberg with the 2 oz. turkey load. How anybody can hate a turkey that bad is beyond me.
