Understanding the Importance of Action Screw Torque
The Mechanics of Action Screws
The Remington 700. A name synonymous with excellence in the world of bolt-action rifles. For decades, this platform has been a cornerstone of the shooting sports, from hunting to target shooting, and even serving in military and law enforcement capacities. Its reputation for accuracy and reliability is well-earned, and much of that performance stems from the meticulous attention to detail, especially concerning one critical aspect: the action screw torque. Getting this right is key to unlocking the full potential of your Remington 700.
To truly understand the importance of action screw torque, it’s essential to grasp the role these unassuming components play in the rifle’s mechanics. The action screws are the vital fasteners that bind the barreled action—the heart of your rifle, containing the barrel, receiver, and bolt—to the stock. This connection, seemingly simple, is fundamental to accuracy. If the action and stock aren’t correctly integrated, the rifle’s performance will suffer.
Imagine your rifle as a finely tuned machine. The action screws act as the critical link connecting the engine (the barreled action) to the chassis (the stock). Proper torque, like a perfectly calibrated setting, ensures everything functions smoothly, allowing the engine to deliver its maximum power. Conversely, improper torque, either too much or too little, creates friction, instability, and ultimately, a significant loss of accuracy.
Consequences of Improper Torque
The importance of this delicate balance can’t be overstated. Incorrect torque can lead to the following:
Inconsistent Bedding: The interface between the action and stock, the bedding, is the foundation of consistent performance. The action screws, when properly torqued, ensure consistent contact between the action and the stock’s bedding surfaces. Any inconsistency in this contact will lead to shifts in the point of impact with each shot.
Stress on the Action and Stock: Over-torquing puts undue stress on both the action and the stock. Excessive pressure can warp the stock, damage the bedding, and even, in extreme cases, crack the stock. It can also distort the receiver, which is detrimental to accuracy. Under-torquing, on the other hand, may allow for excessive movement between the action and stock, again, leading to inconsistency and a wandering point of impact.
Reduced Vibration Control: During firing, significant vibrations course through the rifle. Proper torque helps to dampen these vibrations by creating a solid and stable platform. This controlled vibration is crucial for a consistent bullet trajectory. Loose screws allow for excessive movement and amplify these vibrations, leading to less predictable shot placement.
Diminished Shot Grouping and Accuracy: The ultimate goal for most shooters is tighter shot groups and improved accuracy. The direct result of proper action screw torque is achieving these tighter groups. By establishing consistent contact and minimizing unwanted movement, we enable your rifle to perform to its maximum capability, delivering consistent and predictable results downrange.
Tools and Materials Needed
So, what do you need to properly address this essential aspect of your Remington 700? The answer is simple: the right tools.
Essential Tools
To achieve optimal action screw torque on your Remington 700, you’ll need a few essential items. First and foremost, a quality torque wrench designed to measure in inch-pounds. This will be your primary tool for ensuring accuracy. Look for one that has a wide range to accommodate the various torque values required for your rifle. The ability to easily read and adjust the torque setting is crucial. A torque wrench is the cornerstone for achieving accuracy.
The next crucial piece is the right Allen wrench or bit. This should be the correct size to fit the action screws of your Remington 700. While many rifles use the same size, it’s wise to confirm before you start. Having a few different sizes available can be helpful. A high-quality Allen wrench will ensure a secure fit and minimize the risk of stripping the screw heads.
Optional Tools and Materials
An optional, but sometimes helpful, item is a good quality screwdriver or bit set. While not always necessary, a set with different head types, including the appropriate Allen bits, can be valuable for accessing screws in hard-to-reach places or if you have multiple rifles with differing screw head types.
Finally, consider thread locker, though use this with discretion and careful consideration of manufacturer recommendations. Thread locker, a liquid compound, helps prevent screws from loosening over time due to vibration. If you choose to use it, select a low-strength or removable formula to avoid damaging the action or stock. Always consult a qualified gunsmith if you are uncertain about using thread locker.
Finding Your Remington 700 Action Screws
Locating the action screws on your Remington 700 is the first step to proper maintenance. The most critical screws are the front action screw, positioned forward of the trigger guard, and the rear action screw, usually located in front of the magazine well, or at the rear of the trigger guard if there is one. It’s essential to identify each screw to apply the correct torque.
Screw Locations
While designs may vary across the vast range of Remington 700 models, the general position remains consistent. Understanding these positions allows for proper maintenance of your rifle, ensuring it remains accurate.
On many Remington 700 models, you’ll easily identify the front action screw, and it’s typically the first to be torqued. The location can be a bit more varied on some custom setups, so refer to the stock or action manufacturer’s documentation if you are unsure. The rear action screw, on the other hand, is typically located just ahead of the magazine well. Again, it’s essential to visually identify these screws before applying any torque.
Recommended Torque Specifications
Now that you understand the importance of torque, and have the correct tools, the next step is knowing the appropriate specifications. This is a crucial step and requires careful attention, as improper torque values can damage your rifle.
General Guidelines and Manufacturer Recommendations
It is difficult to provide absolute values for every possible configuration; therefore, it’s crucial to understand the considerations involved.
When you are working with a factory stock, a good starting point is in the range of thirty to forty inch-pounds. This general range provides a balance between securing the action and preventing damage to the stock. This range is typically safe.
If you’re using an aftermarket stock, such as from McMillan, Manners, or other reputable manufacturers, it’s vital to consult their specific recommendations. These companies have extensively tested their stocks and can provide the precise torque values that will ensure optimal performance. Their recommendations should *always* take precedence. Typically, you can expect torque values in the range of thirty-five to sixty-five inch-pounds, but this is merely an example. The manufacturer will be able to provide a more exact value.
Considerations for Bedded Actions
For rifles with bedded actions, the process requires even more care. The torque values in these situations may differ depending on the type and quality of the bedding job. Again, consultation with a gunsmith is recommended. A professional gunsmith can provide detailed instructions regarding the proper action screw torque for the specific bedding arrangement.
Important Reminder: Always consult the recommendations provided by your stock manufacturer. The torque values provided here are general guidelines, and should not be treated as a definitive set of numbers for every setup. Applying excessive torque beyond the manufacturer’s specification may lead to damage to your stock or action.
Step-by-Step Instructions for Torquing Action Screws
The application of proper torque is not about blindly cranking on a screw; it’s about a methodical process that will ensure a precision connection.
Preparation
Before starting, be absolutely sure that your rifle is unloaded and safe. Always practice safe gun handling. Remove the bolt and ensure that the chamber is clear of any ammunition. A stable and well-lit workspace is essential for this work.
Procedure
Place your rifle into a secure rest, such as a gun vise, or any other arrangement that will provide stability. The goal is to prevent any movement during the torquing process.
Set your torque wrench to the appropriate value, as determined by your stock’s manufacturer. The torque wrench should be set in the correct units – inch-pounds or, if your wrench uses ft-lbs, use a conversion factor.
Position the Allen wrench or bit securely into the screw head. Apply slow, steady pressure to the wrench, paying attention to the reading on the torque wrench. You should tighten the screws in a criss-cross pattern – front then rear, and then repeat to ensure even pressure and that you are not over-torquing.
Once the torque wrench reaches the pre-set value, stop. The action screw is properly tightened. Never force the screw beyond the indicated torque.
Following the initial torquing, it’s a good practice to re-check the torque after firing several rounds. This will allow you to confirm that the screws haven’t loosened from recoil.
If you have chosen to use thread locker, this is the point where you’d apply it to the threads *prior* to torquing the screws. However, if you aren’t familiar with using it, you should seek guidance from a professional gunsmith. The specific method of thread locker application will vary depending on the product.
Factors Affecting Action Screw Torque
Numerous factors can affect the appropriate action screw torque, and it’s critical to consider them.
Stock Material
The material of your stock is a significant factor. Wood stocks, for example, are generally less resistant to stress than synthetic stocks, such as those made from fiberglass or carbon fiber. Over-torquing a wood stock can easily cause damage. When working with a wood stock, lower torque settings are commonly preferred.
Bedding Type and Thread Conditions
The type of bedding also plays a role. Pillar bedding, where the action sits on metal pillars within the stock, allows for higher torque values because the pillars provide a solid, reinforced foundation. Full bedding, where the action is fully encased in an epoxy resin, also allows for higher torque, but the bedding material will still have its limits.
The condition of the screw threads is essential. Ensure that the threads are clean and free of any debris or rust. This will allow for accurate torque readings. Using a thread lubricant is also an option.
Environmental Factors
Temperature and humidity can influence the stability of the stock material. High humidity levels can cause wood stocks to swell, potentially affecting the fit of the action. Extreme temperatures can also alter the stock’s dimensions, so it is wise to torque at a moderate temperature.
Stock Age and Condition
The age and condition of the stock should also be taken into account. Older stocks may be more prone to stress cracking, so a lower torque value might be appropriate. Always inspect the stock for any signs of wear or damage before beginning the process.
Potential Problems and Solutions
Even with diligent care, problems can arise. Here are some of the most common and their solutions:
Common Issues and Remedies
Screws can loosen over time due to vibration, or from excessive recoil. Regularly checking your torque, and using thread locker can prevent this.
Stripped screw threads are a sign of damage. If the threads are damaged in the receiver, this will require professional repair. If the threads are damaged in the stock, the screw might be able to be repaired using a thread insert, or the stock could require replacement.
Stock damage, such as cracks or warping, can result from over-torquing or other stress factors. Always be cautious when working with wood stocks, as they can be especially susceptible to this.
Troubleshooting Inaccuracies
If you are using proper torque, and are still experiencing accuracy issues, examine other factors. Verify your scope is properly aligned, and that your ammunition is well-suited for the rifle.
Conclusion
