As two beginning shooters (dad - .22, son - .177 BB/pellet) with no family background in shooting, can you please recommend a good book or online training resource etc for learning rifle shooting techniques - stance, aiming etc. As non-citizens we cannot join our local club (citizens only) and are using public ranges and private land. I’ve taken Hunter Ed (for safety and possible future hunting), and have trained my son on safety (4 rules etc) using many of the great online resources. However I could not find similar information for actual shooting technique. Thanks!
