You need to become a little concerned when you start designing a new house around your gun's. I do know a few that do have in excess of 300 guns, one way in excess.
This attitude is all too common in The People's Republik. Especially in Sacramento...![]()
I really have no basis of knowledge for answering this question as I do not own any firearms.
(My daughters have a sizeable collection that I store for them, however.)
Guns are like children:
If you have more then you can afford to feed then you have too many!
(and that fits me with the price of ammo these days!)
