This video details the critical process of adjusting trigger pulls on British side-by-side shotguns, emphasizing its impact on marksmanship. Expert gunsmith Jack Rowe demonstrates how to measure current pull weights using an RCBS gauge and then carefully modifies the sear geometry to achieve ideal target weights. The process involves partial disassembly, precise filing of sear noses, and iterative testing to ensure accuracy and safety.

Quick Summary

Trigger pull weight is critical for shotgun accuracy as it affects shooting timing. Adjustments are made by filing the sear nose angle to decrease pull weight, aiming for around 4 lbs for the front and 4.5 lbs for the rear trigger on British side-by-sides.

Frequently Asked Questions

Why is adjusting shotgun trigger pulls important for shooting accuracy?

Trigger pull weight is critical because the brain calculates lead based on expected trigger timing. If the pull is too heavy or light, the shot timing is off, causing the shooter to miss in front of or behind the target.

What are the ideal trigger pull weights for a British side-by-side shotgun?

An English trained gunsmith suggests ideal weights of approximately 4 pounds for the front trigger and 4.5 pounds for the rear trigger. The rear trigger typically needs a slightly heavier pull due to leverage.

How are shotgun trigger pulls adjusted?

Adjustments are made by carefully filing the angle of the sear nose. Reducing the angle allows the sear to release from the hammer notch more easily, decreasing the pull weight.

What tools are needed to adjust shotgun trigger pulls?

Essential tools include an RCBS trigger pull gauge for measurement, fine files for precise sear modification, and a bench vise for holding components securely during filing.
