How to Measure Length of Pull on a Shotgun
When it comes to shotguns, fit is crucial for accuracy and comfort. One of the most important aspects of shotgun fit is the length of pull (LOP), which refers to the distance from the rear of the stock to the trigger. A shotgun with the correct LOP will allow the shooter to hold the gun comfortably, with their cheek against the stock and their eyes aligned with the sights. In this article, we’ll explore how to measure the length of pull on a shotgun.
Why Measure Length of Pull?
Measuring the length of pull is essential for several reasons:
- Accuracy: A shotgun with the correct LOP will allow the shooter to hold the gun steadily, which is critical for accuracy.
- Comfort: A shotgun that fits comfortably will reduce fatigue and discomfort during extended shooting sessions.
- Safety: A shotgun that is too long or too short can be dangerous, as it may cause the shooter to lose control or drop the gun.
How to Measure Length of Pull
Measuring the length of pull is a relatively simple process. Here are the steps:
- Determine the Shooter’s Height: Measure the shooter’s height from the top of their head to the soles of their feet. This will give you a starting point for determining the correct LOP.
- Measure the Stock: Measure the length of the stock from the rear of the stock to the trigger. This will give you the raw measurement of the LOP.
- Calculate the LOP: Use the following formula to calculate the LOP:
LOP = Stock Length – (Shooter’s Height x 0.75)
For example, if the shooter is 5’8" (173 cm) tall and the stock length is 14.5 inches (36.8 cm), the LOP would be:
LOP = 14.5 – (5.8 x 0.75) = 12.3 inches (31.2 cm)
What is the Ideal Length of Pull?
The ideal LOP varies depending on the shooter’s height and preferences. However, here are some general guidelines:
- Small Shooters: 12-13 inches (30-33 cm) for shooters under 5’5" (165 cm)
- Medium Shooters: 13-14 inches (33-35.5 cm) for shooters 5’5"-5’9" (165-175 cm)
- Large Shooters: 14-15 inches (35.5-38 cm) for shooters over 5’9" (175 cm)
Tips for Measuring Length of Pull
Here are some additional tips to keep in mind when measuring LOP:
- Use a Caliper: A caliper is a precise measuring tool that can give you an accurate measurement of the stock length.
- Measure from the Rear of the Stock: Make sure to measure from the rear of the stock, not from the butt plate or the comb.
- Consider the Type of Shooting: If you’ll be shooting in a fixed position, such as on a bench, you may prefer a shorter LOP. If you’ll be shooting off the shoulder or from a standing position, you may prefer a longer LOP.
- Try Different LOPs: If possible, try different LOPs to see what feels most comfortable and natural.
Conclusion
Measuring the length of pull on a shotgun is a crucial step in ensuring a comfortable and accurate shooting experience. By following the steps outlined in this article, you can determine the correct LOP for your shotgun and ensure a snug, comfortable fit. Remember to consider the shooter’s height, type of shooting, and personal preferences when measuring LOP. With a properly fitted shotgun, you’ll be able to shoot with confidence and accuracy.
Table: Ideal Length of Pull by Height
| Height (in) | Height (cm) | Ideal LOP (in) | Ideal LOP (cm) |
|---|---|---|---|
| 5’5" | 165 | 12-13 | 30-33 |
| 5’7" | 170 | 13-14 | 33-35.5 |
| 5’9" | 175 | 14-15 | 35.5-38 |
| 6’1" | 185 | 15-16 | 38-40.5 |
