I think that if your shots are within 100 yards, the 44 mag will take deer as well as anything else. But if you need more range or if you want to reduce your recoil, I would go to the 7-08 in the encore, or 7-30 or 30-30 AI in the contender since you reload. Any of these should get you out to 175-200 yards with a spire point bullet if you can shoot that well. The main thing to do is get your rig set up as soon as you can, and put in the time to practice, practice, practice. Your familiarity with your pistol will be as much a factor of cleanly killing a deer as your caliber selection.
