Are you talking rifle or Archery? If you are talking late Rifle, you can go hunting probably every 3-5 years on average. Between me and my hunting partner, we have over 15 guys that apply from ND and we have hunted late bulls every year for the last 6 years. Someone always gets a tag, and one guy has had 3 in 6 years. Good unit, right on the edge being considered a Premium trophy unit. Success rate for us is about 90% on the hunt with 100% opportunity on bulls. Best bull killed so far is in the 330" range with one of the guys screwing up on a 370" and 350" in the same hunt.
Archery is a different story, grab a snickers, it is going to be a while. The unit we hunt takes 12 points b4 a non-res has a chance to draw. All the bonus tags take up the 10% cap on Non-res. In 2016, our structure is said to change, and the odds for a non-res without max points goes up fractionally. Let me know if you have any questions, I would gladly help you.
