overkill?
Only if you plan on moving more than 20 feet.
You are hundreds of miles from home when the SHTF...you have no car..you head for the hills on foot. You come to the outskirts of town where there is a gun shop. The shop has been looted and the owners have left, but there are still many guns still there and lots of ammo.
You have only a backpack to carry stuff out.
The question is: What caliber of guns do you take? Keeping in mind that you have to take ammo too.
I would take a .22 rifle and a pistol with about 2,000 rounds of ammo. Also a 9mm pistol with about 400 rounds of ammo.
wouldnt need to. i could just stake my claim at a grocery store entrance and spray n pray if needed, create a few alliances with people and create a fortress out of a large grocery store. The food inside should hold over a few adults for at least a year I'd think, if food was rationed.
After that if reprieve hasnt been accomplished from the fallout, we could use our wealth of accumulated supplies to barter and trade for goods we needed and hunt our own food.
or sell it all on ebay move to france, should be any hostility there!
realistically though i'd probably just hijack someones 4x4 excursion diesel. plenty of shelter and room for weapons/other essentials. and i could make it a battering ram with some excessive metal plating and a welding machine!
either a .223 or .308 AR and a shotgun, screw a pistol I don't want to be within pistol range of anything in that type of scenario. I want to be a ghost and not be seen and if I have to use a gun I want to be from as far away as possible, time and space are your friend ESPECIALLY in shtf.
