I'm shooting a .270 Win. just because that's what I own. My load is a 130gr. TSX traveling at 2800 (chron'd) with a BC of .431. It's not a barn burner, but it shoots accurately out of my rifle. I'm also using a rangefinder to get accurate readings on distance.
I've zeroed my rifle for a 225 yard zero and have practiced that far and I'm 100% confident in my setup. It will shoot MOA or better out to here.
So I wanted to make a card to look at for reference, just in case I get a good broadside shot at a nice animal that is further than I've originally planned, I'd rather be prepared than have no idea.
I asked on this forum for measurements and settled on 27" for an elk from top of back to bottom of belly. This dimension easily splits up into 3's for holdover.
Here's what the math says my bullet will do:
300: -7.1
350: -13.9
400: -23
500: -48
Granted,..I don't want to take a long shot, I'd much rather settle for a nice 100 yard shot. But, I've got to ask, and I'm wearing my flame proof shorts.
Using the math above, and splitting an elk into thirds of 9", I came up with this drawing.
Does this look like an accurate depiction of drop and where you would hold-over, using my numbers..?

375 yards would be holding at the top of the back. (probably the farthest I'd shoot)
425 yards would be holding a 1/3 high.
500 yards would be holding one elk width high.
Again,..I probably wouldn't even take such a long shot with my setup, but I'd like to know if my math is right or if I'm close.
What say you,...Fire away....
