I hunt Roosevelt elk on public land in western Washington logging country. They only occur west of the Cascade crest, they're a different species than Rocky Mountain elk, and their antlers are much smaller compared to their body size than you'd see with Rocky Mountain elk.
I don't know much about points and inches and thirds, but I'd shoot any elk that passed the old-timer test, which is if an old-time elk hunter walked into a bar in a logging town and saw my elk hanging on the wall, then I'd want him to say, "That's a pretty good bull."
I'd shoot a bigger one if I saw it, but around here you probably shouldn't pass up many animals.
