The Berdan primed cartridge, a relic of a bygone era, presents a unique challenge for modern shooters. If you own a 68 Tower rifle (or any firearm utilizing Berdan primed ammunition), you've likely encountered the frustrating reality of unavailable or scarce ammunition. This leads many to explore the option of converting their rifles to use more readily available Boxer-primed cartridges. This comprehensive guide delves into the intricacies of Berdan bolt conversion for your 68 Tower rifle, exploring the process, considerations, and potential challenges involved.
Understanding Berdan and Boxer Priming
Before diving into the conversion process, it's crucial to understand the difference between Berdan and Boxer priming. This distinction forms the core reason for the conversion necessity.
-
Berdan Priming: Berdan primers feature two small, separate flash holes ignited by a firing pin striking the primer cap's base. These primers are less common today due to their more complex manufacturing process. This complexity often leads to higher manufacturing costs and reduced availability.
-
Boxer Priming: Boxer primers, conversely, have a single, centrally located flash hole at the base of the primer cap. This simpler design makes them far more prevalent in modern ammunition production.
The conversion process aims to bridge this incompatibility, enabling your 68 Tower rifle to fire Boxer-primed ammunition.
The Berdan Bolt Conversion Process: A Detailed Overview
Converting a Berdan primed rifle to Boxer priming is a complex undertaking, generally not recommended for the average gun owner. It requires significant gunsmithing expertise, specialized tools, and a deep understanding of firearm mechanics. Attempting this conversion without proper skills could lead to severe damage to the rifle or, worse, serious injury.
The process generally involves:
-
Assessing the Rifle: A thorough inspection of your 68 Tower rifle is the first step. This includes evaluating the bolt's design, chamber dimensions, and overall condition.
-
Bolt Modification (if necessary): Depending on the rifle's design, the bolt might need modification to accommodate the Boxer primer. This may involve reshaping the firing pin, enlarging the firing pin hole, or making other adjustments to ensure proper primer ignition.
-
Chamber Modification (potentially): In some cases, minor adjustments to the chamber may be necessary to ensure consistent and safe firing of Boxer-primed ammunition. This should only be undertaken by a qualified gunsmith with specialized equipment.
-
Testing and Evaluation: After the modifications are complete, rigorous testing is essential. This involves firing various Boxer-primed cartridges to verify functionality, safety, and accuracy.
Considerations Before Undertaking the Conversion
Before embarking on a Berdan bolt conversion, carefully consider the following:
-
Cost: The cost of professional gunsmithing services can be substantial. Factor in the cost of parts, labor, and testing.
-
Risk: There's a considerable risk of damaging your 68 Tower rifle or causing an unsafe condition if the conversion isn't performed correctly.
-
Legality: Check your local and national laws concerning firearm modifications. Some modifications may be restricted or require permits.
-
Alternatives: Explore alternative solutions, such as sourcing Berdan-primed ammunition or selling the rifle if maintaining it with Berdan primers proves impractical.
Finding a Qualified Gunsmith
Locating a qualified and experienced gunsmith is paramount. Seek recommendations from fellow shooters or gun clubs. Verify the gunsmith's expertise in modifying historical firearms. A skilled professional will assess the feasibility of the conversion, provide realistic expectations, and ensure the process is undertaken safely and effectively.
Conclusion: A Careful Approach is Crucial
The Berdan bolt conversion for a 68 Tower rifle is not a project to be taken lightly. It necessitates expertise, precision, and a profound understanding of firearm mechanics. Always prioritize safety, seek professional assistance from a qualified gunsmith, and meticulously follow all legal requirements. While this conversion offers a potential solution for ammunition scarcity, the risks involved demand a careful and measured approach. The cost and potential dangers should be weighed against the alternatives before proceeding.
