About Length of Pull Calculator (Formula)
The length of pull (LOP) calculator is a tool commonly used in firearms and shooting sports to determine the optimal length of a rifle or shotgun stock for a shooter. This calculation helps ensure proper fit and ergonomics, enhancing comfort, accuracy, and control. The formula for calculating the length of pull depends on the shooter’s individual measurements and preferences.
The general formula for calculating the length of pull is:
Length of Pull = Length from the shooter’s shoulder to the trigger hand + Length of the trigger pull
To use the formula, you need to know the length from the shooter’s shoulder to the trigger hand, which can be measured from the shooter’s shoulder joint to the inside of the trigger finger. Additionally, the length of the trigger pull, which is the distance the trigger moves backward when pulled, should also be considered.
For example, if the length from the shooter’s shoulder to the trigger hand is 14 inches and the trigger pull length is 2 inches, the length of pull can be calculated as follows:
Length of Pull = 14 inches + 2 inches = 16 inches
The length of pull calculation helps determine the optimal stock length for a shooter, considering their unique body proportions, shooting stance, and shooting style. It plays a crucial role in achieving proper eye alignment with the sights or optics, comfortable shouldering of the firearm, and consistent trigger control.
It’s important to note that the length of pull can vary based on individual preferences and shooting disciplines. Some shooters may prefer a slightly shorter or longer length of pull to suit their shooting technique or body mechanics. Additionally, specialized shooting disciplines or firearms, such as those used in competitive shooting, may have specific recommendations or regulations regarding length of pull.
By utilizing the length of pull calculator, shooters can customize their firearms to fit their individual needs, promoting better shooting performance, reduced recoil effects, and improved overall shooting experience. Seeking professional guidance from firearm experts or experienced shooters can further enhance the accuracy and suitability of the length of pull adjustments.
