Dont worry. My son is 13. He used to only shoot 22s. He always said he didnt want to try any of my big bore stuff. But them my wife went to the range with us. She was shooting my pistols and he decided it was his turn. He now shoots all of my handguns except my 44 mag. Just be safe. You will be fine. Have fun.
Romans 1:16 I am not ashamed of the gospel, because it is the power of God for the salvation of everyone who believes: first for the Jew, then for the Gentile.
