Re: sighting in a revolver
For hunting, I prefer the dead on hold, meaning dead on the very top of the front sight. That way, it's not covering up the entire target. The problem with the 6 o'clock hold is that it's easy to do on a standard target at a known distance, but what if it's closer or farther and you don't have that nice target picture but the blank brown slate of the side of a buck? If you do 6 o'clock at 25 yards and that means it's say 4 inches below the center of the bullseye, what is 4 inches on the side of that buck? What's it at 42 yards?
The best thing to do is practice on targets that approximate the look of the deer, not nice round bulls-eyes. Draw a faint outline on a big brown piece of cardboard and shoot it at differing distances and angles. I think you will come to prefer the dead on sight picture.
