Piercing rounds magazine — Factorio Production Calculator
Piercing rounds magazine is crafted in the assembling machine in 6 seconds, producing 2 per craft from 2 × Firearm magazine, 1 × Steel plate, 2 × Copper plate. At 60 per minute you need 6 assembling machines, and the chain behind it draws on 2 raw resources: iron ore, copper ore.
Production chain for 60 Piercing rounds magazine / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Iron plate | 390 | 20.8 | Furnace |
| Piercing rounds magazine | 60 | 6 | Assembling machine |
| Firearm magazine | 60 | 2 | Assembling machine |
| Copper plate | 60 | 3.2 | Furnace |
| Steel plate | 30 | 8 | Furnace |
Raw materials
| Resource | Per minute |
|---|---|
| Iron ore | 390 |
| 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.
Piercing rounds magazine recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 6 s | 2 | Firearm magazine × 2, Steel plate × 1, Copper plate × 2 |
What the whole chain needs
60 piercing rounds magazines per minute pulls in 4 intermediate products, and the whole tree comes to 40 machines across 2 machine types, fed by 2 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.

FAQ
How many assembling machines do I need for 60 piercing rounds magazines per minute?
6 assembling machines. One at standard speed produces 10 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 piercing rounds magazine take?
At 60/min the chain consumes 390 iron ore per minute, 60 copper ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is piercing rounds magazine needed for science packs?
Yes — it goes directly into Military science pack. Open the science pack page to see the demand that lands on this recipe.
