Rossimp; bluefish,
AGREED 100% - As I said, at 72YO & with "not the best" eyesight, even with a scope, I wouldn't even attempt a shot at a game animal beyond 250M, especially given that you cannot SEE an animal, in the area where I usually hunt. = The brush IS thick enough that 100M is a LONG shot (other than an occasional shot down a powerline right-of-way).
In some places on "the lease" you cannot clearly SEE an animal beyond 40-50M.
