No it is not too late though you are 11 bonus points behind and this year Montana is squaring bonus points like they do in Nevada. With that said however, you can still have a chance to draw since they are bonus points (more chances) and not preference points (he who has the most points gets the tag). If you are the lucky type you could certainly draw a tag right out of the chute. Granted, your odds will not be quite as good as those NRs with squared bonus points, but even with max points the odds for a NR are lottery type odds. Odds last year were on the order of 1:200 to 1:300 without respect to bonus points for the better units. Also NR's are limited to 10% of the region's tags and are in the same drawing pool as the residents. There are not to many opportunities to hunt sheep on a draw tag so you might as well throw your name in the hat and fight it out with the rest of us NRs...
Good luck if you decide to apply!
