| Cartridge | Bullet Weight (grains) | Bullet Sort | Muzzle Velocity (ft per second) | Muzzle Vitality (foot-pounds) |
|---|---|---|---|---|
| 9mm | 115 | Full Metallic Jacket (FMJ) | 1,180 | 355 |
| 9mm | 124 | Jacketed Hole Level (JHP) | 1,120 | 345 |
| 9mm | 147 | Jacketed Hole Level (JHP) | 985 | 317 |
| 10mm | 180 | Full Metallic Jacket (FMJ) | 1,200 | 575 |
| 10mm | 200 | Jacketed Hole Level (JHP) | 1,150 | 588 |

When it comes to penetration, the 10mm usually reveals deeper penetration in comparison with the 9mm, particularly with heavier bullet weights. This is because of its larger kinetic vitality and infrequently extra strong bullet development. In commonplace ballistic gelatin testing (a standard strategy to simulate the human physique), the 10mm might be anticipated to constantly penetrate deeper, typically by a number of inches.
The idea of stopping energy is a debated subject. Whereas usually cited as the only real measure of effectiveness, it’s a multifaceted concept that entails extra than simply the whole quantity of vitality delivered to a goal. A bullet should penetrate deeply sufficient to succeed in very important organs. The 9mm and 10mm rounds have demonstrated an effectiveness when utilized in real-world situations, though a bullet’s design is essential to its effectiveness.
Felt Response and Management
One other essential issue to contemplate is the felt recoil and dealing with traits of the cartridges. The 9mm, with its decrease vitality, produces considerably much less recoil than the 10mm.

- Decrease vitality in comparison with the 10mm, probably leading to much less penetration.
- Not ultimate for searching massive sport.
- Wound cavity could also be much less dramatic in sure cases.
The 10mm provides the next benefits:
- Greater vitality ranges, leading to higher penetration and impression.
- Appropriate for searching medium-sized sport.
- Good for protection towards harmful animals.
- Glorious accuracy.
Some disadvantages of the 10mm:
- Greater recoil, making it more difficult to manage.
