Short answer
Explosive ammo is attractive when the path is short, the shooting angle is safe, and sulfur efficiency matters. It becomes risky when the raid is loud, exposed, or likely to attract counters before you finish.
| Door | Explosive ammo estimate | Risk note |
|---|---|---|
| Sheet Metal Door | 63 | Efficient if you can shoot safely. |
| Garage Door | About 150 | Longer exposure; watch counters. |
| Armored Door | 200 | Often too slow under pressure. |
