Measuring the Length of Pull on a Shotgun: A Guide
When it comes to shooting a shotgun comfortably and accurately, the length of pull (LOP) plays a critical role. LOP is the distance between the middle of the buttstock’s recoil pad and the back of the comb (where the shooter’s cheek comes to rest). A poorly fitting LOP can affect your shooting form, making it uncomfortable, inaccurate, and even dangerous. Therefore, it’s essential to measure and adjust the length of pull to ensure a proper fit. In this article, we’ll show you how to measure length of pull shotgun.
Why Measure LOP?
A proper LOP is essential for several reasons:
• Comfort: A shot gun that fits comfortably on the shoulder reduces fatigue, allowing you to shoot more accurately and for longer periods.
• Accuracy: A properly fitted LOP ensures a consistent shooting stance, reducing movement and enabling accurate shot placement.
• Safety: A stock that fits properly reduces the risk of accidents, such as dropping the gun or experiencing muzzle climb.
Measuring the Length of Pull
Measuring the LOP involves taking note of your shoulder-to-axilla distance (the point where the shoulder meets the upper arm). This can be done in two steps:
Method 1: Using a Measuring Tape
- Remove the shotgun’s stock from the receiver or action (if applicable).
- Hold the stock against the back of your shoulder blade, with the recoil pad positioned where the shoulder naturally wants to sit.
- Wrap a flexible measuring tape or a soft, corded tape measure around the stock, keeping it flush against your body.
- Note the measurement of the LOP in inches or centimeters.
Method 2: Measuring the Length of Pull without Removing the Stock
- Sit comfortably on a chair with your shoulder blades relaxed against the backrest.
- Carefully slide the shotgun butt forward, with the recoil pad against your shoulder blades, until you feel natural resistance.
- A small, soft and pliable stick or string can help determine the correct LOP by inserting it between your shoulder blades and the shotgun stock. Stop when resistance is felt, indicating a proper fit.
- Record the LOP in inches or centimeters, as measured from the edge of the comb to the tip of the recoil pad.
Calculating LOP Adjustments
Typically, shotgun stocks adjust up to ½ inch in length (13mm). To find the required adjustment, simply subtract the desired LOP from the current measurement or add to achieve the optimal length. Keep in mind that LOP adjustments will also affect the gun’s fit on the shoulder. Consider consulting with a certified gunsmith for precise assistance.
Recommended LOP for Shotguns
Average Length of Pull (LoP) Measurements for Stock-Fitted Shotguns*:
| Class | Measured LoP (inch/cm) |
|---|---|
| Adult males | 13.8-15.5 inch / 35-39 cm |
| Adult females | 12.7-14.2 inch / 32-36 cm |
| Youth, intermediate, or smaller users | 12.6-14.1 inch / 32-36 cm |
Keep in mind these are general guidelines and measurements may vary depending on personal preferences and individual characteristics. A well-fitting gunsmith or expert can guide you through the process for an optimal LOP configuration.
Additional Tips for Adjusting the Length of Pull
- Install recoil pads or spacers: Consider adding recoil pads or spacers to change the LOP. Spacers are more suitable for temporary adjustments, while recoil pads provide a more lasting solution.
- Tweak the comb height: Comb height adjustment can alter the LOP. Increase or decrease the comb’s height to find the best fit for your shooting preference.
- Experiment and refine: It’s common for individuals to need some trial and error to determine the ideal LOP for their shotgun.
Conclusion
