Not enough for your target to know the difference. I have two .44 revolvers. A Ruger Super Red hawk and a super black hawk. I'm 6'4" 275 lbs I'm not ripped but in good shape and I would argue that anything much more powerful isn't going to be much more effective because the recoil is not going to allow you get that second shot on target fast enough. If it's good enough for Dirty hairy it's good enough for me.
