We're looking at a picture here so it's impossible to get perspective really but in the field I would hope a good marksman would know the difference between something at 200 yards and something potentially double that distance. However, if you had 400 yard dope dialed in and it's actually 200 yards away, your round is sailing over it and conversely if it's more like 400 and you have 200 dialed in, you're kicking up dirt.
Here's my work:
I'm taking some liberties with dimensions but it's a natural animal and this gives me a fair spread. The red circle is a .6 mil wide "kill zone", roughly.
32" @ 2.65 mils = 351 yards
I don't know the exact height of course but 32" seemed reasonable.
24" @ 1.9 mils = 335 yards
We can't see the bottom of the paws so I fudged where I predicted they would be behind that shrub.
Averaged together I'm looking at about 343 yards.
Plugged in for my 6.5 Creedmoor slinging factory Hornady 140 ELD-M's at 2695 fps, my dope for 343 yards is 1.4 mils. As long as the actual target distance is between 310 - 370-ish yards there's a high probability I'm within the .6 mil circle.
Using data from a Tikka T3x CTR pushing Hornady 143 ELD-X's at 2495 fps the same 343 yard range would require 1.8 mils and reduces my margin of error to 320-360 yards give or take.
16" AR -15 shooting Hornady 62 gr Spire Points at 2967 fps would be about 1.5 mils of elevation for 343 yards and gives me a margin of error of between 330-370 yards.
All of those hypothetical calculations assume a 100 yard zero.
