My uncle probably owns twice that. It's just one of his many hobbies, collecting and shooting guns at his private range out in the woods. All of them are locked up in gun safes or have trigger locks and most of the time he has no ammo in his house save for his CCW, and if he does have ammo, its in a separate gun case. He usually just goes out and buys ammo at Walmart the day he wants to go shooting (sometimes in the thousands of dollars worth). He owns everything from .22 revolvers to 30-06 scoped rifles to glocks to a P90 semi-auto carbine with 50 round clip. Although he has enough guns to arm a small militia, he is not a violent person and has never shot anyone. He works in a really bad section of Atlanta, which is the reason for his CCW. I can sorta see why he likes guns so much, they can be incredibly fun to shoot but they are not cheap to own and maintain.
