I have no idea. Half of the guns I own now were given to me by family members, they belonged to my grandfathers or great uncles and I just don't shoot them. The number of guns is not really an issue for me, it is the space to store guns as I really don't want to buy another safe. At this point I have pretty much decided it is one in/one out, but that may change in the future (especially if our friends in Washington make it more difficult to sell or trade used guns)
