Sniper Ammo Mutation: Drop sources, locations, and probabilities

Tips

There are many ways to get Sniper Ammo Mutation in Warframe, but my recommendation for optimal efficiency would be to try one of these missions (in this order):

• Kuva Fortress/Pago : It's a Spy mission (level 31-33). The item is dropped on rotation B (10.00%).
• Uranus/Rosalind : It's a Spy mission (level 27-29). The item is dropped on rotation C (7.04%).
• Neptune/Nereid : It's a Spy mission (level 30-32). The item is dropped on rotation C (7.04%).
• Pluto/Oceanum : It's a Spy mission (level 32-36). The item is dropped on rotation C (7.04%).
• Sedna/Kelpie : It's a Spy mission (level 35-40). The item is dropped on rotation C (7.04%).

These recommendations are based on the usual missions lengths, and the probability of getting the resource dropped.

Missions with a Chance to Get Sniper Ammo Mutation as a Reward

Warframe Rotations Explained

• Survival: One reward every 5 minutes, following this pattern: AABC.
  Rotation A at 5 and 10 minutes, B at 15 minutes, C at 20 minutes, etc. Then it starts all over again (25min is rotation A).
• Excavation: One reward after each excavator successfully completed, following this pattern: AABC.
  Rotation A for the first two excavators, rotation B for the third and rotation C after four.
  Then it restarts from the beginning (5th excavator is rotation A).
• Spy: One rotation level gained per vault unlocked.
  First vault is rotation A, two vaults is rotation B, all three vaults unlocked is rotation C.
