Congratulations on a nice looking Coyote and a sweet looking Rifle!
I know it can be be pretty exhilarating when Hunting and Shooting Coyotes,if possible next time You shot one or call 2 in after shooting the first one try calling again or use the Coyote/Pup yelp and the second Coyote may stop for 1 last look and You'll get a chance at another one and get a double!
What grain bullet are You using in Your .223?I'm using 55 grain V-max Hornady's in my Savage Axis XP Camo Rifle and they do a great job of putting down the Predators!
