I guess I'm getting old, but big hot loads just wear me out thinking about them. I've gotten to the point where if a standard 12 ga. load is supposed to be something like 1 1/8 oz. at 1200-1250 fps, and that doesn't kill them, move on to a 10 ga., or learn to shoot, or get sneaky in the field. Don't start setting off bombs to make up for shortcomings.

ps - don't get me wrong, I'm not adverse to putting an extra 1/8 oz in every once in a while if I'm in a bad mood. Everyone has their little failings.
