Why would I leave my castle?
Does it matter? The question pertained to bugging out, not in-place castle defense, but if it makes you happy, your castle is uninhabitable because of fire, flood, chlorine gas, manure, and the introduction of plague carrying rats and small pox corpses...in that order. Staying in place is not an option.
I am going to go way out on a limb with the perfect firearm for SHTF.
.357 revolver (preparing for flames)
My rationale:
1) SHTF is not battlefield combat. No need for a 30-06. No need to shoot 400 yards.
It is SHTF. How do you know it won't be battlefield combat?
Arguing specifics for what an unknown situation will not be is a good way to misplan or under plan.
In following the events that unfold with various disasters (regional fires, floods, hurricanes, social unrest), there is a repeated pattern that seems to prevail those that whine the most. The first is that they didn't think it could happen to them. They didn't think it could happen that fast. They didn't think it could happen that bad. As a result, they under prepare and are forced to leave with too little time, at the last moment or after the SHTF without the right gear because they have not prepared properly or actually believed the situation could be as bad as it turned out to be, and then they want to blame everyone but themselves for not getting out in time, getting out with enough stuff, and getting out without feeling like a complete victim.
