I have had the privilege of hunting long enough and in game-rich areas, that I have been
able to shoot a considerable number of game animals.
I have a number, but it would raise eyebrows, so will not post it.
The large majority of these have been shot in the heart/lung area.
While bang-flops have occurred, they are not in the majority, by far.
Most have been accompanied by a few steps, a short run, or even a bit longer run.
Only one animal has managed to escape, to be recovered the next day. [my fault, entirely!]
I am not concerned at all if my animal does not drop in it's tracks.
If I am confident the shot hit where it was supposed to, the animal is not long for this world.
I have shot 40 Elk. Of that number, only 3 dropped where they stood. One made it about 80 yards.
The rest moved from 10 feet to 55 yards or so. Most were shot through the lungs.
Moose are odd critters. Frequently when shot in the lungs, they will stand around, acting as if nothing happened.
Then when they decide to move, they just tip over, dead, lol.
I have a firm belief in the proper placement of the FIRST shot on any animal. I make that my goal.
