Last I checked, the rule in Vermont was "any centerfire." Under that rule, seems like even the .17 would be "legal." If I remember correctly, the .223 is legal in about 38 of the 43 states that permit hunting with rifles.
.223 will work, IF, he waits for the right shot, and executes the right shot properly. The Remington Managed Recoil ammo, or a .243 are better choices.
