Therein lies the difference. The tools used will determine the path taken to get the job done.
Comparatively speaking, a 55gr out of a .223 is not terribly flat shooting. All the more reason for a closer scope zero distance and know bullet drop beyond that if/when it is actuallly needed to make a shot. Which again, is a rarity.
Using MBPR zero of 258 yds for a 5" vital zone with that load will get a MBPR of right at 300 yds. However, with that 258yd zero, bullet impact is over 3" high at 100 yds. Definitely not practical when targeting a 5" vital zone. I'd rather the former scenario with that setup and being 1.8" high @ 100. Real easy to hold a tad low at such a predictable distance. Just like with a bowsight pin...
I'd argue that an eastern coyote's build is somewhat more "stocky", i.e. deepr in the chest, than it's western cousins, but I'm no wildlife biologist. Possibily due to the fact that whitetailed deer have become a major prey item and increased musculature aids in their predation? The term "brush wolf" is used by some when describing these big S.O.B.s.
With respect, I was attempting to correct your inaccurate statement about holding off of fur to compensate for 7" bullet drop @ 300yds to get a vital hit on a coyote.
Indeed holding the horizontal crosshair parallel across the back of a big coyote will put your bullet right in his boiler in that scenario. Hence the photo to support that claim.
For a furred up winter coyote, figure 2" of fur then 5" of body mass will = a DEAD DOG. Doesn't have to be a 40+lber either.
Either way, knowing your bullet's trajectory past your rifle zero, or MPBR, can only help you to harvest more game.
Live target sizes are simply too static for accurate, reliable, precision ranging via reticle stadia. If it were only that easy....
Seems like this discussion touches upon a few of the many facets of competent marksmanship in the field. I'm always open to learning from others.
EDIT:
DAA, I just ordered your 3 DVD set...
Good shootin'
