Would it be difficult for you to rename the ammo box ammo category to include the keywords 'bullet' and 'minigun'? I'm making a mod which turns guns into actual projectile weapons, and having those keywords would allow my code to detect that the ammo should have bigger spread.

On another note, if you modify vanilla prototypes, you don't need to copy it, modify the copy, and apply it to the original. You can modify it directly.

Hi, prepared renaming of ammo category for next version to "wtx-bullet-crate" (instead of "wtx-ammo-crate") for the next version.
Sorry, not naming anything "minigun", I don't like that term.

As for the protos, I just found it easier to start that way with copy/copy-back, but that might change in time.

Also, you can find my discord handle in the mod info if you want to talk about anything that relates to Factorio guns ;-)

Update: Renamed the ammo category. Let me know if that mod you are making works with it
