Lateral Danger Space

Imagine a guy is hunting with a .17 Remington Magnum. He is shooting 25 grain Hornady Hollow Points with a Muzzle Velocity of 4,040 feet per second and a G1 Ballistic Coefficient of .151. The weather conditions are 100 degrees below zero Fairenheit, 200 feet below Sea Level, and a 200 mile per hour crosswind that is constantly changing directions.

He sees an animal with a 36 inch kill zone 985 yards away and he only has one bullet left. Normally, his Danger Space would be considered to be 7 yards. However, if you look at the situation laterally, his bullet is only in the specified kill zone for 2 yards (assuming he dopes the wind correctly).

This is because the bullet experiences 733 feet, 6.195 inches of lateral wind deflection at 985 yards. The distance at which it is still within +-18 inches of the target laterally is only approxiamtely one yard in each direction of its point of impact. Could this be defined as a "Lateral Danger Space" and would it be relevant to this man's situation?

    A basic oversight: If you factor in the average height of the toggle pocket, you'll find that the age of the captain isn't actually relevant (a tip here would be to remember that there were only 7 apples in the bucket).

    OK, all the B.S.'ing aside, I for one would like to know:

    Why the continued obsession w/ 'danger space'? Does it have some special significance that the rest of us are missing, other than it sounds cool?

    Compared to the margin of error of correctly doping the wind, combined w/ actually shooting accurately at distance, it's a relatively minor concern as I see it, especially given the relative accuracy of modern ranging systems, from mil-dots to lasers.

    Is there a reason why you would consider it otherwise?
