For a deer slam you need: whitetail, muley, coues (pronounced cows), columbia blacktail and sitka blacktail.

Elk, caribou and moose have their own subspecies, and thus, their own slams.

Elk: American and Roosevelt
Moose: Shiras, Canada, Alaska-Youkon
Caribou: Quebec-Labrador, Woodland, Mountain, Central Canada Barren-Ground, and Barren Ground

If you gun hunt, from what I understand, B&C states that the animals must make book. Also, B&C may require the Tule elk for the Elk slam. I'm not sure though.

Hope this helps.
