The 6mm BR (6mm Benchrest) cartridge has earned a stellar reputation among precision shooters for its accuracy and versatility. Many shooters find converting a factory rifle to 6mm BR is a cost-effective and rewarding path to building a custom-feeling rifle. But choosing the right factory rifle as a base is crucial for a successful conversion. This guide explores the best factory rifles for converting to 6mm BR, considering factors like action type, barrel quality, and overall platform suitability.
Understanding the 6mm BR Conversion Process
Before diving into specific rifle recommendations, let's briefly outline what a 6mm BR conversion entails. This is not a simple drop-in barrel swap; rather, it involves several key steps:
- Barrel Change: The factory barrel must be removed and replaced with a 6mm BR-chambered barrel. This requires specialized tools and gunsmithing skills. The new barrel should ideally be custom-made for optimal accuracy.
- Bolt Face Modification: In many cases, the bolt face needs to be modified to properly headspace the 6mm BR cartridge. This is crucial for safe and reliable operation and often necessitates professional gunsmith work.
- Magazine Modification: The factory magazine might not accommodate the 6mm BR cartridges. This may involve adapting the existing magazine or utilizing a different magazine entirely, possibly requiring custom work or aftermarket solutions.
- Action Trueing (Optional): While not always necessary, some gunsmiths recommend action trueing (precision machining of the receiver) to ensure optimal accuracy.
