"There was 54 tags on the bonus side for the Wasatch early every body with 10 points drew in 2016.So I don't know we're your getting your information." -arns
Nope. For Wasatch early rifle there were 102 bonus tags and it took 15 points to guarantee the tag. Wasatch late rifle had 54 bonus tags, and it took 12 points to guarantee the tag. This is straight from the DWR draw odds sheet: https://wildlife.utah.gov/hunting/biggame/pdf/2016/16_big_game_odds_report.pdf (page 255 and 256)
Here is something to consider---the Wasatch will for the first time have the "middle season" rifle hunt this year. Those tags, if I'm not mistaken, will come out of the early and late rifle tag allotments. We don't know how many will be removed from each or how those tags will impact draw odds at the top of the bonus point pool. But you will have the benefit of seeing that this year.
You have lots of options to guarantee a hunt with a rifle in 2018 with 15 points in your hand. Wasatch early will not be one of those guarantees, though.
