Depends on the mod, if they add new ammo to the game then no you can't craft it, but if the mod uses the vanilla ammo then yes it will work. I would need make a compatibility patch if there's enough interest.

I admit a compatibility patch for this and Brita weapons would be pretty nice, assuming its not too much of a headache.

This and Brita's Weapons Pack would be really cool... but well, even if the mod add new ammo, this still works, the only donwside is that you wont be able to craft ammo for those specific new calibers?

+1 for Brita weapons

Would also love to see compatibility with Brita!

Brita's would be worth a patch due to popularity. I also think Vanilla Firearms Expansion would be worth a patch as it's also very popular and it only adds two calibers, making it an easy patch.

I would also enjoy a brtita's version, if at all possible.

A version for Vanilla Firearms Expansion would be very nice if not too much trouble - it adds several ammo types currently unsupported and isn't totally oversaturated (in my opinion) with new guns like Brita's.
