1. What is a Shotgun Length of Pull Calculator?

Definition: This calculator determines the optimal length of pull (LOP) for a shotgun based on stock length and adjustment factor.

Purpose: It helps shooters and gunsmiths customize shotgun fit for improved comfort, control, and accuracy.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( LOP \) — Length of pull (inches)
• \( S \) — Stock length (inches)
• \( A \) — Adjustment factor (inches, typically 0-2)

Explanation: The stock length is adjusted by a personal comfort factor to determine the ideal distance from trigger to buttplate.

3. Importance of Length of Pull

Details: Proper LOP ensures comfortable shooting position, better recoil management, and consistent sight alignment.

4. Using the Calculator

Tips: Measure your stock length from trigger to buttplate, then add an adjustment factor (default 0.5 inches) based on clothing thickness and personal preference.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical length of pull for shotguns?
A: Standard LOP ranges from 13.5-14.5 inches for adults, but varies based on shooter size and arm length.

Q2: How do I measure my stock length?
A: Measure from the center of the trigger to the center of the buttplate in a straight line.

Q3: When would I increase the adjustment factor?
A: Increase for winter clothing thickness, longer arms, or personal preference for extended reach.

Q4: What if my calculated LOP feels wrong?
A: The calculation provides a starting point. Fine-tune based on actual shooting comfort and performance.

Q5: Does this work for youth shotguns?
A: Yes, but youth models typically have shorter LOP (12-13 inches) to accommodate smaller shooters.
