Pete,
excellent point made by stating "a brick house". Few too many of us have paper thin walls which allow a .22caliber LR to penetrate! Anythin in the .30 caliber and above will probably penetrate two or more walls like a hot knife through butter. You also must take into affect your FOF's like Pete and TR so stated. Defending one's home and family is allot of planning, planning and planning. I also like how TR has eloquently placed each category of weapons in thier PROPER place on the distance scale of usage.
To "bug out" or to not "bug out" that is the question. If you have members in your family that are incapacitated by illness then your chances of "bugging out" becomes a matter of debate, especially when invalids and the very old are in question. Guys with such persons in their families are handicapped when it comes to moving far distances. You need to decide right now if it is worth moving before it happens, during it, or staying put and having a plan to defend your castle.
On a side note, I know of allot of cops who have built homes as far away as possible in order to be away from the masses in a SHTF scenario. Some have even bought land near the Alleghenies in Pennsylvania and West Virginia. Land in West Virginia is dirt cheap if you don't mind owning a mountain and the high ground and views for miles. Just my .02 worth.
This an excellent thread I hope that it stays alive! Allot to be learned here by the QP's!
