Ballistics data for a 9mm FMJ (Full Metal Jacket) 115-grain (gr) ammunition typically includes the following information:
- Muzzle Velocity: The velocity of a 115-grain 9mm FMJ round when it is fired from the muzzle of a firearm. This can vary depending on the specific brand and load, but it’s generally around 1,100 to 1,200 feet per second (fps) for standard 9mm ammunition.
- Muzzle Energy: The energy of the round when it leaves the muzzle, which is typically measured in foot-pounds (ft-lbs). For a 115-grain 9mm FMJ round, the muzzle energy is typically around 330 to 350 ft-lbs.
- Trajectory: The trajectory of the bullet over a specific distance, usually provided in tables or graphs for various distances. The bullet will follow a parabolic path due to the force of gravity, so the trajectory will change with distance.
- Effective Range: This is the range at which the bullet is still considered effective for hitting a target. Effective range can vary based on factors like the firearm used and the shooter’s skill, but for self-defense purposes, 9mm ammunition is generally effective out to around 25-50 yards.
- Accuracy: The accuracy of a 9mm FMJ round can be influenced by various factors, including the firearm, barrel length, and the shooter’s skill. Generally, 9mm ammunition is accurate at close to medium ranges, but it may experience some drop and decreased accuracy at longer distances.
- Recoil: The recoil of a 9mm round is relatively manageable compared to larger calibers. The recoil will depend on the specific ammunition, firearm, and other factors, but in general, 9mm has mild to moderate recoil.
It’s important to note that these values can vary based on the manufacturer, specific load, and other factors. Always refer to the manufacturer’s information or test the ammunition in your specific firearm to get precise ballistics data for the ammunition you plan to use. Additionally, factors like barrel length, temperature, and altitude can affect the ballistics of a round.
