The quieter the better in a shtf situation. Noise might bring 2 legged predators. A suppressed 22lr would be an ideal hunting weapon. Head shots would be best. I watched a Utube video where the hunter took 2 rabbits sitting together with head shots from a suppressed 22lr rifle. The 2nd rabbit did not move when the 1st rabbit was hit. Standard velocity and most target are subsonic. Most HV is subsonic in a pistol. The subsonic rounds are usually more accurate because of sound barrier buffeting. http://www.ballisticsbytheinch.com/22.html

How come we always hear of Social Security running out of money but we never hear of Welfare running out of money?
