One could add the cannon shells as well. I'd be happy to help, if needed.

I have just added normal cannon shells and explosive cannon shells! Sorry that took so long, I looked at the thread a while ago and thought I would get to it later that day and then totally forgot about it.

well I just remade the mod myself, maybe we can work together

Hm. Not sure how exactly you would be able to help. If you have any ideas for the mod I am always open for suggestions. I recently started work on a tungsten cannon shell and could use ideas for the recipe, so if you have some suggestions for what the recipe should look like that would be helpful!

I already have tungsten ammo in my mod https://mods.factorio.com/mod/OCs_ammo_casting so and I am currently working on some compatibility with the More Ammo mod.

Oh nice! More ammo is a bit of a pain to work with but for the most part its not too bad to add compatibility.

I've noticed the pain in particular with the "tungsten ammo" with no tungsten.

Yeah, I saw that and got excited because I thought that it was a bullet type that got scrapped, which would mean adding tungsten rounds would be even easier.
