I built a chart on a spreadsheet last fall after I missed a nice bull elk on my fly in. On one axis it has mph and on the other yards. I plug bullet velocity and I get approximate lead.

The guess work comes in with how fast you figure the critter is running. I guessed the dogtrot at about 5mph which gave a lead of about 8 inches at 2600ft/sec.

So my point of aim was about an inch or two ahead of the coyotes chest.
