That depends on where you bug out to. For me personally, my bug out plan is into the wilderness feeding off of hydroponics systems. For the area I’m going to, I am stocking up on blow darts, and arrows/heads more than bullets and gun. There is simple reasoning behind this. Each bullet you can only use once. Blow darts and arrows you can use many times each. In my terrain has A LOT of trees so I can make arrows. Besides this the terrain, my specialty is wilderness survival and I can disappear quickly into the woods, a silent weapon is better.
I say guns are more for getting to the bug out location and for use if you are in the city/town and plan to bug in. The problem with guns is that each bullet can only be used once and then its gone forever. I am going to get guns and ammunition as a quick defense on my way to the bug out location.
