RE: Best 22 Caliber for Deer... and why?
.22-250 my son is 6 and he uses this caliber it is deadly. Teach them patience and make them wait for the right shot and you will have no problems. I forgot to mention have them practice with the gun so shoting it is second nature. The one my son uses is cut down to fit him and the stock is filled with sand I also put a bipod on it. This helps cut down what recoil there is. The bipod also comes in handy sometimes.
