Was reading on another forum and a guy was asking about advice for a .22lr as a SHTF weapon. His premise was simple enough: 1) Light weight + less report / muzzle flash = easier to evade 2) Cheaper ammo = greater amounts of practice = more accurate shot placement 3) Ability to carry larger quantities of ammo on person vs larger caliber weapons All of this sounds reasonable to me but he was slammed pretty hard (i.e. Limited effective range, limited penetration, all round poor defensive choice). Conversely I come over heat and read the SHTF firearm thread and just about every response suggest picking up a 10/22 or some other .22lr rifle. What I am trying to understand is what is the purpose of the 10/22? In the post the other guy was going to use this as his primary SHTF weapon with a .40 or .45 pistol for CQC / HD. Is that a poor idea? Would you guys use a .22lr for SD in a pinch (remember his basis is to evade when possible) or would you suggest a .22lr only for small game hunting and pick up another long gun (AR-15, AK-47, centerfire hunting rifle)?
