The little diminutive .30 cal carbine is a bear killer for sure. Many years ago I met with and talked to a former Airforce AP who had been stationed in Greenland. He said that the carbine is what they were issued and when something happened to a plane or chopper and it went down that they had to go out and rescue those on board. They were always in a race with Polar bears to get there first. Many a bear met its end due to the little carbines. But only if other lives or their own were endanger.
