I am unable to insert empty magazines and shells, including both extended and standard versions, into your Reverse Factory machine. I can recycle them in the Space Age recycler just fine.
Also, I cannot recycle the extended magazine versions of the ammo, piercing, slowdown, etc.
I've already informed the author of the More Ammo mod. Perhaps the problem is on his end, I don't know.

My initial thought is that the internal names of the item and the recipe do not align, aaand yup, that is exactly the issue. My mod checks the internal recipe name, looks for a matching item with the same name, and then makes a recycling recipe for that item. If the names don't match, then recycling recipe is not made.

Technically speaking, this is more of an issue with More Ammo: unless otherwise necessary, the item name should match the recipe name, as it does in vanilla. The only time the internal names do not match in vanilla, is when there are several processing recipes for the item in question (like solid fuel being craftable from heavy/light/petroleum) or for things like uranium processing and kovarex enrichment.

In theory, I could add a manual compatibility patch that force-creates a recipe for a given item, but it would be preferable if they could just fix their own mod.
