Well,
I don't know if this helps you any but I'll give you a little rundown of the people in my life:
1. Me: My collection is specifically US military and is relatively complete. I own less than the "super owner" but not by much.
2. Coworker: Not a gun guy at all (he deer hunts with "one with a lever") but pretty avid hunter and has more guns than I could count on the couple times I've been to his place. Probably a "3X Super Owner."
3. ULTRA violently liberal best friend: Doesn't shoot, doesn't carry, owns a Mossberg 500 and a little break action 32. Ol' boy is pretty good at breaking clays whenever I get him out there though!
I suppose my point is this: I'm not really a gun guy (I like them but it's more about the history - you won't see any NRA or Molon Labe stickers anywhere near me), my coworker isn't a gun guy, and my friend is DEFINITELY not a gun guy...but on average, we own something like 12-15 guns each.
