Length of Pull Calculator



 

About Length of Pull Calculator (Formula)

Firearms enthusiasts and hunters understand the importance of a properly fitted firearm. One of the key elements in achieving a comfortable and accurate shooting experience is the length of pull (LOP). The Length of Pull Calculator, often represented as P=(WS−15)/2, is a valuable tool used to determine the ideal length of pull for a firearm. In this article, we’ll delve into what the Length of Pull Calculator is and how it contributes to enhancing your shooting accuracy and comfort.

Understanding the Length of Pull Calculator (P=(WS−15)/2)

The Length of Pull Calculator (P=(WS−15)/2) is a mathematical formula designed to help firearm users and enthusiasts determine the correct length of pull for a given firearm. Length of pull refers to the distance from the trigger to the part of the buttstock that rests against the shooter’s shoulder. It plays a crucial role in firearm ergonomics and can significantly impact a shooter’s comfort, accuracy, and overall shooting experience.

The formula is represented as:

P = (WS − 15) / 2

Where:

  • P: Length of Pull (in inches)
  • WS: Shooter’s Wingspan (in inches)

How to Use the Length of Pull Calculator

Using the Length of Pull Calculator is a straightforward process:

  1. Measure the Shooter’s Wingspan (WS): The wingspan is measured from fingertip to fingertip with arms stretched wide. It is crucial to measure it accurately, as it serves as a key input in the formula.
  2. Plug the Wingspan Measurement into the Formula: Insert the measured wingspan value (WS) into the Length of Pull Calculator formula:

    P = (WS − 15) / 2

  3. Calculate the Length of Pull (P): Use the formula to compute the recommended length of pull (P) for the firearm in question.

Significance of Using the Length of Pull Calculator

  1. Improved Shooting Accuracy: A firearm with the correct length of pull allows the shooter to maintain proper eye alignment with the sights or scope. This results in improved accuracy, especially during extended shooting sessions.
  2. Comfort and Recoil Management: An appropriate length of pull enhances shooter comfort by ensuring that the firearm fits snugly and comfortably against the shoulder. It also aids in managing recoil more effectively.
  3. Reduced Fatigue: A well-fitted firearm reduces shooter fatigue, making it easier to maintain a steady aim and fire accurately over extended periods.
  4. Customization: The Length of Pull Calculator can be used to customize firearms for individual shooters. It is especially useful for gunsmiths and firearm enthusiasts who want to optimize their firearms for specific purposes.
  5. Safety: A properly fitted firearm is safer to use because it helps prevent accidents caused by improper handling or poor firearm fit.

Conclusion

The Length of Pull Calculator (P=(WS−15)/2) is a valuable tool for anyone who uses firearms, from hunters to competitive shooters. Achieving the correct length of pull is essential for enhancing shooting accuracy, comfort, and overall shooting performance. By using this calculator, shooters can tailor their firearms to their specific needs, ensuring that the firearm fits them comfortably and ergonomically. Whether you’re a novice shooter or a seasoned marksman, understanding and applying the Length of Pull Calculator can significantly improve your shooting experience and results.
