Perry, I'd just shoot it at 200 and see what adjustments are needed. I use a similar round for crows, a .220 Swift with 52 gr. hollow points. I want mine sighted in at 200, no more than that, as the bullet rise (in comparison to the line of sight) has caused me to miss crows at closer distances when I forgot to hold low. With coyotes that shouldn't be near as much of an issue, as the vital area is so much bigger than that of a crow. With my .22 Magnum I sight in at about 100 yds.
Because I don't shoot them enough to remember the drops I like to keep a tiny cheat sheet taped to the top of the ocular bell of my scope, with holdovers (and unders) from 50 out to about 350 yards. Handy and quick to check.
