Spartacus, I freely admit that I won't take a neck shot much over 100 yards.
I just wish I had the eye-finger coordination that my father had. I've watched him call the white spot at over 200 yards, offhand; and four credible witnesses watched him kill a buck with a called neck shot at around 450 yards, offhand.
I watched my Uncle Joe stomp the brakes of the jeep, grab his rifle, and break a buck's neck in mid-leap over a fence, at around 125 yards. Joe's comment, one time in reference to the Springfield '03 was, "When I was your age, if it jumped up inside 300 yards, I owned it."
Some folks "just have it".
