It'll probably work with dedicated SP hunting rounds. But if a hunter can shoot a .223, he or she can almost certainly also shoot the .243 well, too, and the extra 30 grains you'll get from a 100 grain .243 round might be good for a thick shoulder bone or a larger deer. I'd prefer that the round punch straight through the animal and not change trajectory inside the animal, and a slightly heavier round might help punch straight through.
Then again, if it works, it works. If a 60 (or whatever) grain .223 can punch through reliability and consistently, I suppose it works. You'll notice my opinion is cautious, because 10 years ago I didn't think the .243 was enough for deer . Now I know better....
