The 6.5x55 Swedish Mauser cartridge, a classic for its accuracy and versatility, sometimes requires reaming for optimal performance. Choosing the right reamer and understanding the process is crucial for success. This guide focuses on finding a 6.5x55 Swedish reamer that avoids overly aggressive jumps, ensuring a smooth and precise chambering experience.
Why a Gradual Jump is Important in Reaming?
An overly aggressive reamer jump – a significant difference between the existing chamber and the new dimensions created by the reamer – can lead to several problems:
- Case Head Separation: A sudden change in chamber dimensions can place undue stress on cartridge cases, increasing the risk of case head separation during firing. This is a safety hazard and can damage your firearm.
- Inconsistent Accuracy: A poorly reamed chamber can lead to inconsistent bullet seating depth and inconsistent pressure, directly affecting accuracy.
- Difficulty in Chambering: Cases might be difficult or impossible to chamber smoothly, leading to frustration and potential damage.
What to Look For in a 6.5x55 Swedish Reamer: Avoiding the “Too Deep” Jump
When choosing a reamer for your 6.5x55 Swedish, focus on these key aspects to minimize the jump:
- Throat Dimensions: Pay close attention to the reamer's throat dimensions. A gradual transition from the existing chamber's throat to the new dimensions is essential. Avoid reamers that specify aggressive throat cuts. Look for reamers that are designed for a "match grade" chamber, implying a carefully designed and gradual throat.
- Reamer Type: Consider the type of reamer. A pilot reamer is often used as a first step to create a uniform base for the finishing reamer. This approach allows for more control and gradual adjustments. A single-pass reamer may be suitable for experienced gunsmiths but carries a higher risk of introducing a substantial jump if not used precisely.
- Manufacturer Reputation: Research the reamer manufacturer's reputation. Look for companies known for producing high-quality, precisely manufactured reamers.
- Consult with a Gunsmith: For best results, especially if you're inexperienced, it's recommended to consult with a qualified gunsmith. They can advise on the appropriate reamer for your specific needs and perform the reaming process correctly.
H2: What are the Common Issues Encountered When Reaming?
One common issue is not correctly setting up the reamer during the reaming process. This can lead to an uneven chamber or an excessively deep jump. Another common issue is using the wrong type of reamer or not following the manufacturer's instructions carefully. Improper lubrication during reaming is also a frequent mistake and can lead to damaged tools and a less-precise result. Finally, lack of experience can lead to inaccurate cuts and problems.
H2: How Often Should You Reame a 6.5x55 Swedish Chamber?
Reaming isn't a routine maintenance task. It's typically only done when:
- Improving Accuracy: When a significant improvement in accuracy is desired.
- Addressing Chamber Issues: When dealing with problems like difficulty in chambering cartridges or excessive wear.
- Specific Cartridge Use: When you are wanting to adjust the chamber for a specific type of ammunition.
The need for reaming will often be determined by careful evaluation of the existing chamber's condition and performance. A gunsmith will be best suited to advise on this determination.
H2: What are the Different Types of 6.5x55 Swedish Reamer Profiles?
There are various reamer profiles available. The details of these profiles often are specific to the manufacturer. Key considerations include the freebore, leade, and throat dimensions. It's essential to select a profile that matches your intended ammunition and goals.
Conclusion
Choosing the right 6.5x55 Swedish reamer and avoiding a "too deep" jump is key to achieving accurate and reliable performance from your firearm. Prioritizing careful selection, a gradual approach, and potentially consulting a gunsmith will significantly enhance the success and safety of the reaming process. Remember that safety and precision should always be paramount.
