Understanding the Need for Barrel Replacement
Reasons for Replacement
The lifespan of a rifle barrel is finite. Over time, the rifling – the grooves that spin the bullet for accuracy – will gradually erode due to friction from the bullet passing through. This wear leads to a decrease in accuracy, with groups opening up and shots straying from the intended point of impact. Furthermore, barrels can suffer from damage. Dents from accidental drops, bulges caused by obstructions in the bore, or rust and corrosion due to improper care can all compromise performance. Sometimes, the desire for a different barrel profile or twist rate is the driving force behind wanting a new barrel.
Benefits of Replacement
Replacing the barrel on your Savage Mark II can be a cost-effective way to restore the rifle’s accuracy, ensuring continued enjoyment for years to come. With a new barrel, you’re potentially getting a tighter grouping, greater consistency, and a renewed shooting experience. This can be particularly beneficial for target shooting, where even small improvements in accuracy can make a significant difference. Beyond performance, a new barrel allows for customization, choosing different profiles such as bull barrels for greater stability and enhanced target acquisition. You might opt for a stainless steel barrel for increased corrosion resistance. The choice of barrel, however, must be done meticulously to make the most of this project.
Planning and Preparation
Safety First
Before embarking on the journey of Savage Mark II barrel replacement, safety is paramount. Ensure the firearm is unloaded, with the action open and visually inspected to confirm no ammunition is present. Always point the firearm in a safe direction throughout the process. Wear appropriate eye protection, specifically safety glasses, to protect your eyes from any debris or potential hazards. A clear, well-lit workspace is also essential for optimal work.
Tools and Materials Needed
Gathering the necessary tools and materials is crucial for a smooth barrel replacement. This ensures you’re not making multiple trips to the store in the middle of the project. Here’s a checklist:
- A new barrel: Specifically, a replacement barrel designed for the Savage Mark II. Research compatible barrels, considering caliber, twist rate, barrel profile (e.g., sporter, bull), and material (e.g., carbon steel, stainless steel). Choose a barrel from a reputable manufacturer known for quality and accuracy.
- A barrel vise: This is used to securely hold the action during barrel removal and installation. It’s important that the vise can firmly grip the action without causing damage.
- An action wrench: A specialized tool designed to grip the Savage Mark II action. It prevents damage to the receiver during barrel removal.
- A torque wrench: For precise tightening of the barrel.
- A cleaning rod and solvent: To clean the bore of the action.
- A vice: Used to hold the action.
- Penetrating oil (optional): To assist in loosening the barrel, especially if it has been in place for a long time.
- Tools for removing any scope or other attachments: This might include screwdrivers, Allen wrenches, etc.
- Gunsmithing tools (optional): A borescope, headspace gauges, and other specialized tools are helpful, but not always essential for a basic replacement.
Choosing the Right Barrel
Selecting the right replacement barrel is an important decision. Consider the intended use of the rifle. For target shooting, a heavier barrel profile and a tighter twist rate might be preferable. For hunting, a lighter, more maneuverable barrel might be a better choice. Read reviews and research to choose a barrel that meets your needs and complements your shooting style. Consider a barrel from a trusted manufacturer to secure the best possible results.
The Core Process: Step-by-Step Guide
Disassembly
Disassembly is the first step in this endeavor.
- Remove the scope: If your Savage Mark II is equipped with a scope, carefully remove it, remembering to take note of the scope’s settings to aid in re-zeroing later. Place the scope in a safe place, protected from dust or potential damage.
- Remove the stock: Unscrew the screws that hold the stock to the action. Once the screws are removed, the stock should separate from the action.
- Optional Disassembly: Further disassembly is not always needed. You can, however, detach the bolt from the action for easier access and maneuverability during barrel work. If you choose to disassemble the bolt, take care to keep all parts organized to ensure smooth reassembly. This might also involve removing the firing pin and extractor for complete access.
Removing the Old Barrel
With the action prepared, the actual barrel removal process can start. Safety remains the highest priority. Ensure the rifle is unloaded and the action is open.
- Secure the action: Position the action in the barrel vise. Ensure the vise securely grips the receiver, without damaging it. Proper clamping will prevent slippage during the barrel removal.
- Attach the action wrench: Securely attach the action wrench to the action. This tool is designed to grip the action and allow you to apply the necessary torque.
- Loosen and unscrew the old barrel: Using the appropriate wrench, carefully loosen the old barrel. You might need to apply a significant amount of force, but do not force it excessively. If the barrel is difficult to loosen, apply penetrating oil and let it sit for a while to help loosen the threads. If necessary, use heat from a heat gun or hair dryer to facilitate the loosening. Work slowly and methodically.
- Note shims or spacers: As you unscrew the barrel, note the presence of any shims or spacers. These may be present to ensure correct headspace and will need to be transferred to the new barrel installation.
- Clean Threads: Thoroughly clean the receiver threads and barrel threads using a brush and cleaning solvent. Remove any old thread locker residue.
Installing the New Barrel
With the old barrel removed, you can now focus on the new barrel.
- Clean threads: Clean the receiver threads carefully. Removal of old debris and contaminants makes for a cleaner install.
- Apply thread locker (if desired): Apply a small amount of thread locker to the receiver threads, according to the manufacturer’s recommendation.
- Hand-thread: Carefully hand-thread the new barrel into the receiver, ensuring it starts straight.
- Tighten the barrel: Use the action wrench and torque wrench to tighten the barrel to the manufacturer’s recommended torque specifications. This is critical for accuracy and safety. Too much torque can damage the action, while too little torque can cause the barrel to loosen over time. Refer to barrel manufacturer’s specifications for accurate torque.
- Check headspace: Checking the headspace is a crucial step. It ensures the bolt will fully close on a cartridge and that the firing pin strikes the primer with proper force. The process involves checking the distance between the bolt face and the base of the chamber using headspace gauges.
Reassembly
- Reattach the stock: Reattach the stock to the action and tighten the screws.
- Reinstall scope: If the scope was removed, reinstall and roughly zero it.
- Double check: Once the stock and scope are reinstalled, double-check all screws and fasteners to ensure everything is securely fastened. Make sure you’re comfortable with the overall feel of the rifle.
Post-Replacement Testing and Maintenance
Testing
Test firing is a crucial step to ensure the rifle is functioning properly and shooting accurately with the new barrel.
- Safe Environment: Find a safe range or shooting location.
- Sight In: Adjust your scope or sights until the bullets hit the desired point of impact.
- Group check: Shoot several groups of shots and assess the size and consistency of the groups. This helps determine the accuracy of the new barrel.
Cleaning
Proper cleaning and maintenance are essential for maintaining the rifle’s performance.
- Clean your barrel: After each shooting session, clean the new barrel thoroughly. Use a cleaning rod, bore solvent, and patches to remove powder residue, lead, and other contaminants.
- Use proper maintenance: Apply oil to the external metal surfaces of the rifle to protect them from rust and corrosion. Follow the manufacturer’s recommendations for the rifle cleaning and maintenance schedule.
Troubleshooting
Common Problems
Sometimes, things don’t go as planned. Here are some common problems that may arise during or after the Savage Mark II barrel replacement and their potential solutions:
- Barrel Issues: If the barrel won’t tighten properly during installation, re-check the action threads and clean them. Ensure the barrel is aligned properly. Check that the action wrench is correctly used.
- Inconsistent accuracy: If the rifle doesn’t group well after the barrel replacement, re-check the barrel’s torque, scope settings, and ammunition choice. Check the headspace again. Sometimes, it might simply be the ammunition.
- Headspace issues: If you experience difficult bolt closure, or the bolt won’t close on a round, or extraction issues, the headspace may be incorrect. This is why headspace gauges are a must in this process, especially if the bolt has issues. The barrel might not be properly aligned.
- Dealing with a stuck barrel: If the barrel is stuck in the action, first make sure the rifle is unloaded. Employ penetrating oil to the threads. Apply heat from a heat gun or hair dryer, making sure not to apply too much heat to affect the other parts of the gun.
