I can still remember the day that my dad bought me my first bb gun... I'd start them out with that let them shoot itand get used to carrying a gun. Then I would suggest you taking them with you when hunting small game. Even if you arent hunting just take them out into the woods. Show them where you hunt.When you think theyre careful enough to handle a gun loaded or not it would be time to take them out. Squirelle and groundhog would be great game to take them out for their first time.
