I could do 3 guns as well. A good .308 (or in my case .303) rifle a shotgun and a rimfire rifle. No handguns but you got the shottie for home protection.

I would go with my parker hale no4 custom ,a Mossy like Andy's with full stock and nice ghost ring sights and because it is legal in Canada a very short spare barrel for home and car and bear defence. Probably one of the nice CZ model .22's but if I could find a nice old Parker hale one I would grab it.
Actually since I am on a PH binge I may replace my old classic no 4 with one of the later Parker Hale .308's the CF used for a sniper rifle before the TimberWolf.
