I guess I "get it" but again, either you're taking a shot you know you can make or you're playing the "pull and pray" game on a live animal. There's not much similarity to me shooting a buck that is standing stationary giving me a good angle with my 45/70 at 20-25 yards and lobbing one in at 400. I can put 10 shotsa into an inch black square with that rifle at 25 yards.
It's not either/or. There is the third, more true situation where you *think* you can make the shot.
If you *know* you can make a shot under field conditions on a wild, untethered animal, there are more things in your favor than a wizard has crystal balls: range, wind, rest, nerves, weapon, load, stationary target, Fate.
(That is only a partial list. It could go on.)
The shots we think we can make are many more than the shots we know we can make.
I'm gonna leave it there, because almost nothing chaps my ass more than the idea/advice that if you're confident, you should take the shot.
Dean Wormer was confident he could run a college, and look where that got him ...
