Ok so my stepson and I were told he couldn't shoot my pistol at a range Saturday. Rifles were acceptable. Has anybody heard of this? BTW, he's not a kid, he's 19. I was told it was a federal law, but I looked at 922 and I didn't see a reference to this. Was the range just looking to turn us away? They said I had to have documented proof of guardianship but how do you even get that for a legal adult?
