handguns stop bear, I am doing my best to not be demeaning [bear defense with hand guns](https://concealednation.org/2018/10/handguns-for-bear-defense-a-study-by-caliber/) AR15 stops polar bear [charging bear](https://www.ammoland.com/2018/03/ar-15-used-to-defend-against-charging-polar-bear-2008/#axzz6njnBqj5q) I understand the love for the 7.62x39 its an incredible round and I own and use it often. A rifle will put many animals down, an AR15 in 5.52/.223 will put down animals readily due to the ballistic advantage of velocity F=mv^2. Your assertion is understandable and widely believed, however, it is incorrect.
