Unless we're calling them in, in my experience; coyotes within the 1/4 mile mark usually know we're there before we see them. They don't usually give us much time to prepare for a shot (range and compute, then dial knobs and so forth)
Therefore, I am a proponent of fast and flat shooting. Less time of flight on moving shots and a broadside yote gives us more lee-way with wind drift than with elevation cause the vitals are oblong.
Either bullet will give you enough energy to cleanly take a yote at the distances you mentioned so long as you hit the vitals. The lighter bullet is a little faster (assuming factory advertised velocities) and gives you a couple inches better trajectory. The heavier one gives you a couple inches less wind drift.
Sixes in all reality, so it probably boils down to which one shoots the best out of your rifle.
I look for consistent 1" to 1 1/2" groups at 300 yds (calm day, bench rest, well tuned load)
Highly recommend a holdover syle reticle. Practice with it and learn/record where to hold at distances out to 600. This will save you alot of time when you're presented with a shot. Time that should be spent on getting into the most stable position possible. Coyotes vitals aren't a whole lot taller than a pop can.
