I'm on planet Castra (all planets mods enabled) and the recipe to make rifle mags with nickel makes pistol mags instead. On that planet iron is hard to get and you are supposed to make those rifle mags with all the nickel you can get. As pistol mags can't be used in turrets or in the castra science it makes things quite hard.

I have a feeling this is an issue about mod loading order since the different recipes all refer to "firearm-magazine" and some of them create pistol mags and some rifle mags. I made a mod for myself to add those castra specific magazine recipes back in to fix this for myself.

Mods used: "Krastorio 2 spaced out" and " Enable all planet mods"
