I stand corrected
John, I see exactly what you mean. It seems to crude a system to be accurate, but what do I know ?
ShaiVong, I believe you are talking about the sights on a No. 4. I see they aren't linear but they don't seem to be far from it either. Again, what do I know ? But it would seem like there would be a huge difference in the drop that must be accounted for.
I would love to see some people actually try this. I think it would be more difficult than many think. Of course one of the more difficult things would be knowing if you actually hit it without checking the target. I have a place to do the experiment; if I think about it, I might just go to the hardware store next week and buy a sheet of something and try it.
I do think the target is big enough that with enough shooting you would hit it. I also think it is big enough that once you got the sight dope you could probably hit it fairly often. However I have a hard time believing that very many people could simply pick up a strange rifle, fire one shot, and hit it. Even with my regular scoped deer rifle which I know is zeroed (my standard big game hunting zero) I wouldn't bet $50 I could hit it on the first shot. Based on those numbers mentioned earlier, it would seem that you might be aiming as much as 2x or 3x the height the target in Kentucky windage. And this isn't even taking into account wind or mirage. Of course if you knew you were making a bet like this, you could consult a chart or software to tell you the projected point of impact from your present zero and then dial in the appropriate number of clicks (assuming the scope has that much elevation without shimming the base) and this should put you within 10 feet.
I don't know, maybe it is easier than I think it is ? I guess there is only one way to find out for sure.
