My buddy bought a shotgun and his parents won't allow him to keep it in their house so he started keeping it in his car. He eventually decided that wasn't a great idea so he asked if he could keep it at my house. I said sure cause he said I can take it shooting whenever I want. I've had it in my possession for about 6-8 moths and will probably have it another 6-8 months or more. Am I legally allowed to shoot that gun? Take it to the range and what not without him? I live in CA if that makes a difference. Thanks for any help you can give.
