When I turned 18, I though you only needed 3 long guns. A big game rifle, preferably a 3006, a 12 gauge shotgun, and a 22 rifle. Started with a 12 gauge Mossburg pump, a Marlin model 60, and a 3006 bolt gun. Then things changed, there were old military guns, upgraded shotguns and rifles, and upgraged 22 rifles, then handguns. It would be hard to go back to just a handful, but it could be done. The above original 3 could put meat on the table, of any size and kind.
