Shotgun shells — Factorio Production Calculator
Shotgun shells is crafted in the assembling machine in 3 seconds, producing 1 per craft from 2 × Copper plate, 2 × Iron plate. At 60 per minute you need 6 assembling machines, and the chain behind it draws on 2 raw resources: copper ore, iron ore.
Production chain for 60 Shotgun shells / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Copper plate | 120 | 6.4 | Furnace |
| Iron plate | 120 | 6.4 | Furnace |
| Shotgun shells | 60 | 6 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Copper ore | 120 |
| Iron ore | 120 |
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.
Shotgun shells recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 3 s | 1 | Copper plate × 2, Iron plate × 2 |
What the whole chain needs
60 shotgun shellss per minute pulls in 2 intermediate products, and the whole tree comes to 19 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 120 per minute, which is 0.13 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 shotgun shells
1 base-game recipe consumes shotgun shells, sorted by how much each one takes:

FAQ
How many assembling machines do I need for 60 shotgun shellss 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 shotgun shells take?
At 60/min the chain consumes 120 copper ore per minute, 120 iron ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is shotgun shells needed for science packs?
Not directly. It feeds Piercing shotgun shells, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
