If your sim lives on a lot with the Simple Living trait, the Marksmanship Skill will come in handy. This skill allows your sim to practice pistol and rifle shooting as well as build their own firearms on the Woodworking Table as they increase their Marksmanship. With the Hunting Spot object (this file is also included in the Archery mod) you can spawn in several critters for your sims to hunt and convert into Wrapped Meat, making it very nifty for historical or apocalypse players.

An additional and optional file lets your sims challenge others to a duel but be warned, the consequences can be fatal!
