Your post does hit some excellent points, and you are spot on about the bench rest shooting. I would like to add one thing.
Myself, I am good to about 150 yards, but in case something did happen, and I hope it doesn’t, the long range shot will be worthless.
Rather than buying up new rifles/pistols/shotguns (I already have a few of each) I am concentrating on ammo.
After all, a gun without a bullet is a very expensive bat, and completely useless at 50 yards.:)
Actually under certain narrow conditions, the long range shot may become invaluable. As has happened in past wars, there will be large moving bodies of troops all over crisscrossing the terrain. A well schooled shooter can halt them in their tracks by harassing these movements. Well, well, well which targets in that unlikely (I hope) scenaro are the most valuable? LEADERSHIP and COMMUNICATIONS folks. Care to guess why I chose the latter? Leadership is obvious. But those kinds of shooters are already out there and already trained and experienced. I'm not one of them.

ME TOO!
