I think elknut hit it right on an elk from New Mexico or the other states or units that are designed to grow such trophy big = something diffrent then in an over the counter tag from Co.

With that said an 320+" bull from one of these trophy managed areas is probably on the small end but 320" from an over the counter is a big bull.
I have shot my best bull this year with bow in a over the counter unit in Co. I haven't put a tape to him yet( just to drive my hunting partners crazy) but he is a true trophy to me and yes he is big in my book for where I was hunting.

You can guess his score .
