Why not use the 64 grain sierra tgk gamechanger?
Out of an 18" .223 they're almost built too stout for these skinny desert coyotes. I've killed probably a dozen coyotes with them with body shots and they all ran off 35-50 yards before tipping over.
Small entrance wound and roughly dime size exit.
Hit a shoulder or the spine and they quit right there.
I'm using those and Federal Fusion 64gr SP mostly for pigs but most times don't have time to swap mags and switch over to 50-52gr HP which are my normal coyote calling bullets.
I'll say one thing about the Sierra's, they're damned accurate in my AR's and Ruger American Ranch Rifle.
