This is "NOT" a survival gun thread. Although kind'a in the same general concept, but not exactly. The difference being that in a wilderness survival situation you goal is to be out of the wilderness ASAP.
This is more of a "walk'about".......wilderness wandering.......exploring application, with "NO" destination to get to. Not hiking a trail system, more just living and exploring a general area for a months or weeks. For sure "NOT" hunting, but maybe scouting an area.
So with that back round and the need to supplement your basic foods that you have earlier cached or are currently packing with small game and fish, we need some type of firearm for both defense and meat for the pot.
The firearm needs to be reliable, versatile, easy to carry, as quiet as possible when fired, and given those needs, it should be fairly light. Could be a handgun or a rifle or a shotgun. The firearm should accept a wide range of versatile ammo.
The goal of this thread is "NOT" inside the box thinking.........the goal is a long list of outside the box firearm suggestions. Think along the line of 30 to 45 days afield, with meat for the pot needed every-other day. There is "NO" perfect answer.......just looking for ideas.
