Ultimate Guide to Pillar Bedding a Rifle: Accuracy & Performance
As a long-time hunter, competitive shooter, and outdoor writer, I’ve spent countless hours behind the rifle, and I’ve learned that a rifle’s potential accuracy isn’t always unlocked right out of the box. One of the most impactful upgrades you can make to improve your rifle’s precision, especially for long-range shooting or demanding conditions, is pillar bedding a rifle. This isn’t just about aesthetics; it’s about creating a stable, consistent platform for the barrel and action, minimizing flex and maximizing shot consistency. In this guide, we’ll dive deep into pillar bedding, covering everything from what is pillar bedding, the benefits, different materials like rifle bedding epoxy and aluminum pillar bedding, and even a comparison of pillar bedding vs glass bedding. We’ll also touch on popular options like Boyds pillar bedding and specific applications like glass bedding a Remington 700.
Why Bed Your Rifle? Understanding the Benefits
Before we get into the “how-to,” let’s understand the “why.” A factory rifle action often has voids between the action and the stock. These voids allow the action to shift slightly with each shot, influenced by temperature changes, recoil, and even the pressure of your grip. This movement, even minuscule, translates to inconsistent point of impact. Rifle pillar bedding addresses this by creating a solid, stress-relieved interface between the action and the stock.
- Improved Accuracy: The primary benefit. A stable action means more consistent shot groupings.
- Reduced Point of Impact Shift: Minimizes changes in zero due to temperature or environmental factors.
- Enhanced Durability: Protects the stock from damage caused by recoil and action movement.
- Increased Rigidity: A properly bedded action resists flexing, contributing to overall stability.
Think of it like building a house. You wouldn’t build on a shaky foundation, right? Pillar bedding a rifle provides that solid foundation for your action.
What is Pillar Bedding and How Does it Work?
Pillar bedding involves filling the voids between the action and the stock with a rigid material, typically epoxy or aluminum. Unlike full-length bedding, which encapsulates the entire action, pillar bedding focuses on supporting the action at key stress points – usually the recoil lug, the magazine well, and sometimes the tang. These “pillars” act as load-bearing supports, transferring recoil energy directly to the stock and preventing the action from twisting or flexing.
Pillar Bedding vs. Glass Bedding: Key Differences
Often, the terms pillar bedding and glass bedding are used interchangeably, but they aren’t the same. Glass bedding is a more comprehensive process that involves creating a complete impression of the action within the stock using a release agent and fiberglass-reinforced epoxy. Pillar bedding, as described above, is more targeted.
| Feature | Pillar Bedding | Glass Bedding |
|---|---|---|
| Coverage | Supports key stress points only | Encapsulates the entire action |
| Complexity | Simpler, less time-consuming | More complex, requires more skill |
| Material | Epoxy or Aluminum | Fiberglass-reinforced Epoxy |
| Cost | Generally less expensive | Generally more expensive |
Both methods improve accuracy, but glass bedding a rifle typically provides a more complete and potentially more accurate solution, while pillar bedding offers a good balance of performance and simplicity. For many hunters and recreational shooters, pillar bedding is sufficient to achieve significant accuracy gains.
Materials for Pillar Bedding: Epoxy vs. Aluminum
Choosing the right material is crucial. The two most common options are rifle bedding epoxy and aluminum pillar bedding.
Rifle Bedding Epoxy
Epoxy is the traditional choice for pillar bedding. It’s relatively easy to work with, fills voids effectively, and creates a strong, durable bond. There are specialized rifle bedding epoxy formulations available, such as Devcon and Brownells Bedding Compound, designed for this specific application. These epoxies often contain fillers to improve strength and reduce shrinkage. Brownells offers a comprehensive guide to bedding compounds.
Aluminum Pillar Bedding
Aluminum pillar bedding involves installing pre-made aluminum pillars into the stock. This offers several advantages: it’s incredibly stable, doesn’t shrink or creep over time, and provides excellent heat dissipation. However, it requires more precise stock fitting and often involves professional installation. Boyds pillar bedding, for example, offers pre-fabricated aluminum pillars designed for specific rifle models. Boyds Gunstocks provides a range of pillar bedding kits.
For DIY projects, epoxy is generally more accessible. For a premium, long-lasting solution, especially for high-powered rifles, aluminum is an excellent choice.
Step-by-Step Guide to Pillar Bedding (Using Epoxy)
This is a simplified overview. Always consult detailed instructions specific to your rifle and bedding compound. I recommend practicing on an old stock before tackling your prized rifle.
- Preparation: Disassemble your rifle and thoroughly clean the action and stock. Remove any existing bedding material.
- Action Fitting: Ensure the action fits snugly in the stock. Identify the areas where pillars will be placed (recoil lug, magazine well).
- Pillar Creation: Using release agent (important!), create forms for the pillars using clay, tape, or commercially available pillar molds.
- Epoxy Mixing: Carefully mix the rifle bedding epoxy according to the manufacturer’s instructions.
- Epoxy Application: Pour the epoxy into the pillar forms, ensuring it fills all voids.
- Action Installation: Carefully install the action into the stock, pressing it firmly onto the epoxy pillars.
- Curing: Allow the epoxy to cure completely according to the manufacturer’s instructions (typically 24-72 hours).
- Cleanup: Remove the pillar forms and clean up any excess epoxy.
- Reassembly: Reassemble your rifle and test its accuracy.
Remember to use a release agent to prevent the action from bonding to the epoxy! RealTree has a detailed article on rifle bedding that covers release agents and other important considerations.
Specific Applications: Glass Bedding a Remington 700
The Remington 700 is a popular platform for precision shooting, and glass bedding a Remington 700 is a common upgrade. The process is similar to pillar bedding, but involves creating a full impression of the action. Due to the 700’s widespread use, numerous tutorials and kits are available specifically for this model. Pay close attention to the recoil lug and ensure it’s properly supported during the bedding process. Many aftermarket stocks designed for the 700 already incorporate pillar bedding features, simplifying the process.
Troubleshooting Common Pillar Bedding Issues
- Epoxy Shrinkage: Use a high-quality epoxy with minimal shrinkage.
- Action Movement: Ensure the pillars are adequately sized and positioned to support the action.
- Difficulty Removing Action: Use a generous amount of release agent.
- Poor Accuracy Improvement: Double-check the action fitting and ensure the bedding is solid and consistent.

Final Thoughts on Pillar Bedding
Pillar bedding a rifle is a worthwhile investment for any shooter looking to improve accuracy and consistency. Whether you choose epoxy or aluminum, taking the time to properly bed your action can unlock your rifle’s full potential. Remember to prioritize safety, follow instructions carefully, and don’t be afraid to seek help from a qualified gunsmith if you’re unsure about any part of the process. Happy shooting!
