Good advice above. Inn .223 I use the 60gr as well, lots of guys like the 50-55gr range.
As long as you can hit with it, that's what matters in a rifle.
Agree with the above. Your choice of a stand should begin before you get there. Is the wind blowing from you to where you think the coyotes are? Can you both see and shoot your down wind?
You really need to be like a ninja. Quiet and invisible going in, while hunting and when you leave.
While keeping the wind in your favor.
How you set up will vary with how you are calling, hand calls vs e caller.
Use good calls. Good sound,
Fwiw in Michigan we have even called them in using monkey distress, so using a "native" sound isn't as important as your set up and quality of sound.
You don't always need to be loud with the calls either, start low volume them go up into the set.
Good camo, and don't move around much
