Gunsmith Part 25: Achieving Superior Accuracy Through Bolt-Action Rifle Stock Bedding
Fundamentals of Inventory Bedding
Understanding the Key Areas for Bedding
The core precept behind inventory bedding is to create an ideal interface between the rifle’s motion (the receiver and the elements housed inside) and the inventory. A well-bedded motion and barrel be sure that each shot is delivered with most consistency. That is achieved by filling any gaps or inconsistencies between the motion and the inventory with a secure, sturdy, and dimensionally secure materials, sometimes epoxy resin.
The manufacturing unit match of most rifles, whereas typically ample for informal taking pictures, isn’t supreme for precision work. There are often small gaps or variations in touch factors that may enable the motion to shift slightly below recoil. These tiny actions, typically measured in fractions of an inch, can considerably impression the bullet’s level of impression downrange. Consider it like a wobbly desk. Even when the desk has a wonderfully flat floor, it will not be secure if the legs aren’t firmly and evenly touching the ground.
Inventory bedding creates a custom-fit “mould” that stops these actions. The bedding compound fills all of the voids, making certain that the motion is securely seated within the inventory and that the barrel is persistently aligned. This results in enhanced accuracy, improved shot-to-shot consistency, and doubtlessly even an extended lifespan to your rifle.
Key Areas for Bedding
Efficient inventory bedding concentrates on particular areas of the rifle: the recoil lug and the motion. These areas are the details of contact between the motion and the inventory, and thus they dictate the rifle’s habits underneath recoil.
The recoil lug is often a steel plate that’s designed to soak up the drive generated when the firearm is discharged. It sits between the motion and the inventory. It’s important to make sure correct contact between the recoil lug and the inventory to transmit recoil forces effectively.
The receiver of the bolt-action rifle, must be bedded. This consists of the areas across the motion screws, that are important for securing the motion to the inventory. A correctly bedded motion promotes stability and eliminates the potential for the motion to shift throughout firing.

Calmly roughen the inside surfaces of the inventory the place the bedding compound will probably be utilized. This improves the mechanical bonding of the epoxy resin to the wooden. Use sandpaper to create a tough texture.
In case your recoil lug isn’t already a good slot in its recess, you could have to mattress it individually for optimum outcomes.
Be sure the screw holes in your inventory are completely aligned and that the motion screws match into their respective locations simply. Use the proper drill bits if wanted.

Making use of the Compound
Apply a beneficiant layer of the blended compound into the ready areas of the inventory: across the recoil lug, alongside the perimeters and backside of the motion, and across the motion screw pillars (if current). Don’t skimp! You need full contact and an excellent, strong basis.
Meeting and Seating
Rigorously place the ready motion into the inventory, ensuring it aligns correctly. Tighten the motion screws, however accomplish that gently. Do not overtighten, as this might trigger the compound to squeeze out excessively.
Checking Alignment and Contact
Now, fastidiously examine your alignment. Use a stage to verify the motion is stage. Verify the contact factors. Be sure that the motion is accurately seated within the compound, with good contact throughout the surfaces you’ve bedded.
Curing and Disassembly
Permit the bedding compound to completely treatment based on the producer’s directions. This often takes a number of hours, generally longer. As soon as cured, fastidiously loosen the motion screws and disassemble the rifle. The motion ought to now be completely fitted to the inventory.
Ending Touches

Mixing Sticks and Cups: For mixing the compound precisely.
Sandpaper: For getting ready the inventory surfaces.
Small Instruments and Applicators: Toothpicks, cotton swabs, and different small instruments to use the compound exactly.
Torque Wrench: For tightening the motion screws to the proper specs.
Degree: To verify the motion is completely stage when assembling the bedding.
Security Concerns: All the time a Precedence
Working with firearms requires a continuing dedication to security:
All the time Deal with Firearms as Loaded: Even for those who consider the rifle is unloaded, deal with it as whether it is loaded.
Eye Safety: Put on security glasses to guard your eyes from particles.
