Best to look into the 500 auto max, 4,000+ ft/lbs of energy with some loads.
Can't be too careful.
Single shot TC Encore rifle length in the 500 S&W with the 700gr hardcast load may take them down too.
Though let's face it, that 440 grain massive hollow point at good speed through that rifle would be amusing on a coyote. The 630gr grand canyon may too, but the 440 could be pushed faster and may explode better.
