A customer took a video of his daughter shooting a 6.5SS that has a Ti Pro 2 muzzle brake on it. For reference, she is 39 lbs, the rifle is 11.8 lbs.
Just use dog years, See there, Easy Peasy he's good to goWhat a great video. My sons 4 and my wife imposed a random rule that he has to be 7 before he can start shooting.
