A friend and I had and argument about this in a hunting for survival situation. I own a lot of .22 rifles and pistols and I was about ready to purchase a AR-7 survival rifle to add to my collection. My Friend hates rimfires and argued that in a survival situation a high powered air rifle will take the same small game as a .22 rifle, and you may be able to salvage the pellet to reuse again. I hunted squirrel with a .22 but nothing bigger, and I admit as a kid I have taken out a squirrel with a CO2 BB gun, so it is possible for the small stuff, but do you guys think they are almost equal?
