I'm building on a post-WW3 campaign setting (haven't upgraded to 6th yet) and I don't have a lot of knowledge when it comes to guns. The story is the world has descended into chaos, and the vast majority of it is nuclear waste sites. Society in the world is nothing more then gangs and "military" factions warring each over (little) food, territory, and what ever else they feel like. The currency in this quite possible world is ammunition, meaning using guns is risky as you need the bullets to buy things. What I'm asking is if the list of firearms in my Big Big Book of Everything would be enough for this game. Looking at the list I think yes, but then again I'm not all that knowledgeable with guns. Other then that if any one would like to help me in getting this campaign as real as possible, I'm working on it here.
