Trading 12ga rounds is just plain wrong, wrong, wrong.
Most especially in the SHTF world where survival is a day to day struggle.
You have to think out the whole trading thing from first point of contact. Who found whom? How many of them are there? Where are the ones you don’t see? How do you know that they even have something to trade? Continue cogitating all the minute elements of the “trading” until you have prepared for a return to your base without leaving tracks.
Truth has left the building in SHTF scenario. Any transaction at this stage should be conducted as though it were a large scale drug buy only more desperate and dangerous as there are no cops to interfere.
Until you start with these questions the 12ga.is a defense weapon.
If you’re trading in a shtf scenario with people you don’t know you already screwed up.
If I have a large surplus of ammo and a person who I know is godly and honest needs some, I will trade. If I get a referral, I will not trade.
Trade must be done between good men to ensure they stay strong. But never ever trade something you absolutely need. So BLOAT if you can.
