So I decided on no sidearm and just sticking with a rifle. I wanted to get the ruger 10/22 takedown (price) but then wondered if a 22 was even effective if it came down to protection from someone else or a large predator (in my bug out situation/location would be either a bear, mountain lion, bobcat). Even though it is more that I want to spend, my eye caught a bushmaster xm-15 m4-a3. Could somone show me a picture comparison of a 5.56 round next to a 22? And also any opinions on the decision or even personal experience with one of the rifles would be greatly appreciated.
