Interesting about the Sierra comment. Way back when, I used their 52-grain HPBT in my Swift, to the ruination of several feral cats out around 300 yards. DRT.
In a .223, most anybody's 50-grain to 55-grain soft points do the horribles to jackrabbits and coyotes. Close-in, GI stuff comes all unglued.
