Uranium rounds magazine — Factorio Production Calculator
Uranium rounds magazine is crafted in the assembling machine in 10 seconds, producing 1 per craft from 1 × Piercing rounds magazine, 1 × Uranium-238. At 60 per minute you need 20 assembling machines, and the chain behind it draws on 3 raw resources: iron ore, depleted uranium fuel cell, copper ore.
Production chain for 60 Uranium rounds magazine / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Iron plate | 390 | 20.8 | Furnace |
| Uranium rounds magazine | 60 | 20 | Assembling machine |
| Piercing rounds magazine | 60 | 6 | Assembling machine |
| Firearm magazine | 60 | 2 | Assembling machine |
| Copper plate | 60 | 3.2 | Furnace |
| Uranium-238 | 60 | 20 | Centrifuge |
| Steel plate | 30 | 8 | Furnace |
Raw materials
| Resource | Per minute |
|---|---|
| Iron ore | 390 |
| Depleted uranium fuel cell | 100 |
| Copper ore | 60 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Uranium rounds magazine recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 10 s | 1 | Piercing rounds magazine × 1, Uranium-238 × 1 |
What the whole chain needs
60 uranium rounds magazines per minute pulls in 6 intermediate products, and the whole tree comes to 80 machines across 3 machine types, fed by 3 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 390 per minute, which is 0.43 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses uranium rounds magazine
No base-game recipe consumes uranium rounds magazine — it is an end product. Once you build it, the chain stops here, which makes it a good target if you only want to size the sub-factory that feeds your mall.

FAQ
How many assembling machines do I need for 60 uranium rounds magazines per minute?
20 assembling machines. One at standard speed produces 3 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does uranium rounds magazine take?
At 60/min the chain consumes 390 iron ore per minute, 100 depleted uranium fuel cell per minute, 60 copper ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
