Trying to remember a movie based on a gun.

Definately not, there were no lever guns in that movie and no one was dumb enough to think the vampires were bears at first. They were definately vampires in everyone's eyes first thing.

Another movie I can think of with a lever gun and a bear in alaska is "The Edge" with Alec Baldwin and Anthony Hopkins, they had a nice Winchester 1886 in the movie. But it doesn't fit all of your descriptions enough.
