This will be my second year drawing the tags here in MT. I learned a lot my first year, here are some thoughts:
1. In MT, there are very few who chase them, so I wouldn't get to spun up on pressure. In the Pacific flyway, you have to draw for a tag; in the Central you can get an OTC permit.
2. Know that there are 2 subspecies that are hunted: lesser and greater. This probably only matters on the size of bird you might want to put on the wall.
3. Both of mine were pass shot over feeding areas I scouted. This seems to be the most effective route. There are plenty of DIY decoy and strategies for them out there if you google it.
4. BB's with Full choke.
5. I bought a call, and used it without dekes. Seemed to pull some in lower to an area they were already on their way.
6. The red meat breast is different than waterfowl. Very good. Don't overcook it.
7. Prep a swatter shot, those beaks can be gnarly if crippled.
8. Find a great waterfowl taxidermist. I called countless places around this area, and only one 300 miles away had done one before.
