Some weapon mods on the site include their own custom ammo models. This is good for those mods, but makes sorting the ammo model categories a bit of a pain.
One possible solution is to move the ammo subcategories to be subcats of the weapons themselves. However this makes the
Items/Ammocategory a touch redundant.
Leaving them as an entirely disassociated category type under
Itemscan be viable as well, but a bit more involved than browsing the weapon category as a catch-all category.
