(Keep in mind, the Boy Scouts no longer exist, they changed their name to BSA to show their new inclusion of girls as well)
Did a little Googling, looks like this is the bill in question, it has to do with someone under 16 being able to shoot a gun at all if they're out of arm's reach of the owner of the gun...
IMHO, that's the plan. Shut off the ability of the youth to enjoy the shooting sports, and in a generation those kids will be adults that have no experience with firearms, and don't care about defending their right to have and use them.
