4 gun rule: pistol (.357/.44/.45), shotgun (12 ga), rifle (.223/.308), long range hitter (bolt or semi) (.308/.30-06/.300 Winchester)
Good advise. About like mine, (2).45, 10 ga, 12 ga, .308, and a .303. Thinking about a mini 14, too.
4 gun rule
9mm,30-30,12ga.,22long,high power .177 pellet ( also good survival weapon)and a single shot 20ga. just to scare.
S&W 32HR/mag, 12 ga beretta, .223 handi-rifle, Christensen .243 ackley ultra long ranger. (and a 45/90 to blow the block out of a truck when necessary)
I can see using a pistol, shotgun and/or an assault rifle for home or auto defense, but unless you have some clear shots at long ranges, I can't see the need for a long range rifle in that role(not that I wouldn't want one for other reasons). If I should ever need to defend my home or car, I want something that I can handle in close quarters. I don't think that any thugs will be considerate enough to back up 500 yards so that I can defend myself with a long range rifle.
