Piercing shotgun shells — Factorio Production Calculator
Piercing shotgun shells is crafted in the assembling machine in 8 seconds, producing 1 per craft from 2 × Shotgun shells, 5 × Copper plate, 2 × Steel plate. At 60 per minute you need 16 assembling machines, and the chain behind it draws on 2 raw resources: iron ore, copper ore.
Production chain for 60 Piercing shotgun shells / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Iron plate | 840 | 44.8 | Furnace |
| Copper plate | 540 | 28.8 | Furnace |
| Shotgun shells | 120 | 12 | Assembling machine |
| Steel plate | 120 | 32 | Furnace |
| Piercing shotgun shells | 60 | 16 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Iron ore | 840 |
| Copper ore | 540 |
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 shotgun shells recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 8 s | 1 | Shotgun shells × 2, Copper plate × 5, Steel plate × 2 |
What the whole chain needs
60 piercing shotgun shellss per minute pulls in 4 intermediate products, and the whole tree comes to 134 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 840 per minute, which is 0.93 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 piercing shotgun shells
No base-game recipe consumes piercing shotgun shells — 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.
What piercing shotgun shells is made from
- Shotgun shells — 2 per craft
- Copper plate — 5 per craft
- Steel plate — 2 per craft
FAQ
How many assembling machines do I need for 60 piercing shotgun shellss per minute?
16 assembling machines. One at standard speed produces 3.8 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 shotgun shells take?
At 60/min the chain consumes 840 iron ore per minute, 540 copper ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Machine counts assume bare machines at standard speed. Recipe data comes from the game's own prototypes (PlayerCalc, Factorio 2.0 base game). Not affiliated with Wube Software.
