I rang up BASC the other day, I am 16 and was wondering what i can do with a shotgun, he said I can shoot unsepervised, walk to my permission with gun and ammo as long as gun is in gun slip. I have just applied for my sgc and my dad has as well so he can buy the gun and pass down as a gift then he can keep buying carts and giving them to me. As soon as im 18 i can then ovbiously just buy the carts and gun, i think at 15 you may have to be supervised. just ring basc very good
