Coming on my third year to hunt MT. First of all, as a non-res. you will have to draw for deer, elk, or antelope. The draw for deer has been 100% until this past year, and I know a few folks did not get a tag. Elk is based on the unit you apply for. You can get a general tag which is 100% but the bull permit may be tough to get for certain units (2 world records were taken in the past two years in Eastern MT so the tags are getting harder. the farther East you go from Billings the less elk there are but they are huge! Especially in the Mo river breaks area. That being said, You should be able to get a deer tag, and an antelope archery no problem. I got both last year and was lucky enough to take a nice whitetail and a great pronghorn. There is quite a bit of BLM land along the Yellowstone that is easily accessed for deer, and all of the islands are loaded with whitetails. Last year I went the first week of Septemeber and temps were as warm as 105 degrees. A couple weeks later, it snowed. So be prepared. I would advise you to check out the Custer NAtional forrest as it has tons of land and lots of good muleys, white tail, and antelope. Also, take a shot gun as we have seen so many pheasants, grouse, and other game birds. good luck!
