Personally, I probably wouldn't go with a bolt action in 44 magnum. I'd go with a traditional lever action for that caliber as the accuracy will be there even with open sights at the distances you'll be using it and followup shots will be easier. The best bolt action IMHO if you go that route is the Ruger carbine. Here is the link to take a look at it:
