What is +P and +P+ Ammunition?

+P and +P+ ammunition are types of ammunition that are loaded to higher pressures than standard ammunition. They are designed for use in firearms that are specifically rated for this higher pressure ammunition.

The “P” in +P and +P+ stands for “pressure,” indicating that the ammunition is loaded to a higher pressure than standard ammunition. This higher pressure can result in increased muzzle velocity and energy, which can improve the effectiveness of the ammunition.

However, it’s important to note that not all firearms are designed to handle the higher pressures of +P and +P+ ammunition. Using this type of ammunition in a firearm that is not rated for it can result in damage to the firearm, and potentially injury or death to the shooter or those nearby.

How Do I Identify +P and P+ Ammunition?

How do you tell if you’re using +P or P+ ammo? +P ammunition refers to cartridges that are loaded to a higher internal pressure than the standard specifications for a given caliber, resulting in increased velocity and energy. This can enhance the performance of the ammunition but may also generate more recoil and wear on the firearm. To determine if your ammunition is +P, you can follow these steps:

  • Check the packaging: The packaging of factory-loaded ammunition often provides information about the pressure rating. Look for labels or descriptions such as “+P” or “High Pressure” on the box, indicating that the ammunition is loaded to a higher pressure than the standard for that caliber.
  • Inspect the headstamp: The headstamp, which consists of markings on the base of the cartridge case, may also indicate if the ammunition is +P. Some manufacturers will include a “+P” or “P+” symbol next to the caliber designation on the headstamp. However, this is not always the case, and some +P ammunition may not have this marking on the headstamp.
  • Consult the manufacturer’s specifications: If you are still unsure, you can refer to the manufacturer’s website or product documentation for specific information about the pressure rating of a particular brand or load of ammunition. This will usually provide definitive information on whether the ammunition is +P or not.

Benefits of +P and +P+ Ammo:

  • Increased Muzzle Velocity: +P and +P+ ammunition are loaded to higher pressures than standard ammunition, resulting in increased muzzle velocity and energy. This can improve the effectiveness of the ammunition in stopping a threat.
  • Improved Terminal Performance: The higher velocity and energy of +P and +P+ ammunition can result in improved terminal performance, meaning that the bullet is more likely to expand and penetrate deeper into a target.
  • Greater Versatility: +P and +P+ ammunition can be used in a wide range of applications, including self-defense, hunting, and target shooting.
  • Better Accuracy: The increased velocity of +P and +P+ ammunition can result in better accuracy, particularly over longer distances.
  • Improved Functioning: In some firearms, +P and +P+ ammunition can improve functioning, particularly in firearms that are designed to handle this type of ammunition.

It’s important to note that while +P and +P+ ammunition offer several benefits, they may not be suitable for all firearms or applications. Additionally, they may be more expensive than standard ammunition. It’s important to carefully consider the intended use and the firearm being used before selecting +P or +P+ ammunition.

Drawbacks of +P and +P+ Ammo:

+P and +P+ ammunition also have several drawbacks to consider:

  • Recoil: The increased velocity and energy of +P and +P+ ammunition can result in increased recoil, which can make the ammunition more difficult to shoot accurately, particularly for inexperienced or smaller shooters.
  • Wear and Tear: The increased pressure and velocity of +P and +P+ ammunition can result in increased wear and tear on firearms, particularly older or lower-quality firearms that are not designed to handle this type of ammunition.
  • Availability: +P and +P+ ammunition may not be available in all calibers and quantities, which can make it more difficult to find than standard ammunition.
  • Cost: +P and +P+ ammunition can be more expensive than standard ammunition, which can be a factor for some shooters.
  • Legal Restrictions: +P and +P+ ammunition may not be legal in all areas, particularly in jurisdictions that have laws or regulations that prohibit the use of this type of ammunition.

As with any type of ammunition, it’s important to carefully consider the intended use and potential drawbacks before selecting +P or +P+ ammunition. Additionally, it’s important to ensure that the firearm being used is rated for this type of ammunition and that local laws and regulations are followed.
