Cheap Hornady regular 55 gr JSP is hard to beat.
I concur. I don't like HP for coyotes. I've had them splash and cause massive fur damage on close range shots.
I knew a guy that killed dozens and dozens of coyotes every season. He eschewed the .223 and favored the .243 because the .223 lacked the snot to knock the coyotes over every time. If anybody would know it would be him because like I say, he kills about a truckload every year.
