A good 22 in what ever platform your hunting guns are in allows lots of relatively cheap practice, to keep you in tune . Tweak what you have to with the hunting guns, saving enough component's back for the next few hunting seasons. We all want our guns to shoot to there potential but they don't have to shoot 1/4 in. groups to be hunting accurate. If you treat the 22 like your big bore ,give it all your concentration with each shot, the practice will carry over to the big bores. Every shot counts ,don't think of it as just a .22 but as a valuable hunting ,training tool.
