Purpose of change

Elephant guns are the only weapon to fire .700 nitro express and they were incredibly rare due to being buried in distributions. Your local antique shop now doubles as an elephant protection shop.

Describe the solution

All medieval weapons in antique_rare got moved to antique_medieval_arms which means now antique_rare is funny rocks and guns.

Describe alternatives you've considered

Convert to Collection but Chaos screamed in pain.

Testing

Additional context

I own an elephant gun for home protection because that's what the founding monster hunters intended. Four dragons break into my house "What the devil?" As I grab my elephant gun and funny baseball cap with an inappropriate slogan that won't age well. Blow a golf-ball size hole in the first dragon, its dead on the spot.

Seems simple enough improvement. Could also replace fixed gun spawns with nested gun groups at some point so they'll spawn with ammo.

I don't think that they would legally sell ammunition but that's a bit of realismic stuff we can probably ignore for now. Balance-wise I don't know if we want a lot of extra ammo.

Fair, might make more sense to be a thing added to other relevant locations assuming mansions and the like can't already spawn with ammo.

I don't think that they would legally sell ammunition

Anybody can sell ammo currently in the US, the restrictions are on making it and then selling it as a business. Any state level restrictions would not survive the legal environment of the pre-Cataclysm backstory (where it's freshly legal to manufacture, trade and possess machine guns, but belt feds haven't proliferated yet, which requires a significant overton window shift and a conservative SCOTUS). @RoyalFox2140 you can always tag me if you need a hot take on guns/legality.
