Time for a quick reality check on .22's, regular, HV, whatever. I compete in action rifle shooting once a month. Usually there at about 10 people on the rimfire squad. And 20 or more would be shooting center fire. I can tell you from personal experience as well as watching others shoot rimfire, that the .22 is a darn finicky caliber. Seen numerous FTF, FTE, underpowered rounds, etc etc. At least twice the rate of failures compared to centerfire (this includes pistol caliber rifles, btw). So would I rely on a .22 to save my life or the life of my family if I had the choice of a centerfire carbine? Hell no. Is a .22 better than a slingshot? Hell yes.
