This video demonstrates the process of pillar bedding a rifle stock, a gunsmithing technique that enhances rifle accuracy and point of impact consistency. Larry Potterfield explains how metal-to-metal contact between the action and guard screws, achieved through pillars, stabilizes the action. The tutorial covers precise drilling using a specialized fixture, installing escutcheons, adjusting pillar lengths, and the epoxy bedding process for a permanent, stable fit.

Quick Summary

Pillar bedding enhances rifle accuracy by creating metal-to-metal contact between the action and guard screws using pillars. This ensures consistent torque and stability, preventing stock deformation and maintaining a stable point of impact over time. Key steps include precise drilling with a fixture, adjusting pillar length, and proper epoxy application for a permanent, stable fit.

Frequently Asked Questions

What is pillar bedding and why is it important for rifle accuracy?

Pillar bedding creates a solid connection between the rifle action and the stock using metal pillars. This ensures consistent torque on the action screws and prevents the stock from deforming under stress, leading to improved accuracy and a stable point of impact over time.

What tools are needed for pillar bedding a rifle stock?

Essential tools include a pillar drilling fixture (like the Score High model), a specialized drill bit (e.g., 5/8 inch), adjustable pillars, epoxy bedding compound (like Bedrock), release agent, and clamping tools for the curing process.

How do you ensure the pillars are the correct length during bedding?

Adjustable pillars are temporarily secured to the barreled action. Their length is then adjusted until they are perfectly level with the stock's trigger guard inletting, ensuring proper contact and alignment when the action is bedded.

What is the purpose of the escutcheon in pillar bedding?

The stock escutcheon is a metal insert that is tapped into place. It provides a precise seat for the front pillar and matches the escutcheons on the cross bolts, contributing to the overall stability and alignment of the action within the stock.
