Identifying the correct cylinder for your Ruger Single Six .22 Magnum revolver is crucial for safety and proper function. This guide will walk you through the process, covering key features and potential pitfalls to avoid. Understanding your cylinder's specifications is essential before purchasing or using any replacement parts.
Understanding Ruger Single Six Cylinder Variations
Ruger Single Six revolvers, renowned for their reliability and versatility, have been produced over several decades. This has resulted in a variety of cylinder configurations, making identification essential. Key variations include:
1. Caliber: .22 LR vs. .22 Magnum
The most significant difference lies in the caliber: .22 Long Rifle (.22 LR) and .22 Winchester Magnum (.22 WMR or .22 Mag). These are not interchangeable. Attempting to fire .22 Magnum ammunition in a .22 LR cylinder will cause serious damage to the firearm and potentially injury to the shooter. Conversely, using .22 LR in a .22 Magnum cylinder is generally safe, but the rimfire cartridges may not consistently chamber. Always double-check your cylinder markings.
2. Cylinder Release Mechanism
Early models used a simple side-gate release, while later models incorporated a more modern, swing-out cylinder design. The release mechanism itself isn't directly tied to caliber but influences the overall cylinder appearance.
3. Manufacturing Dates and Variations
Ruger's manufacturing process has evolved over time. Minor variations in the cylinder's design, markings, and finish may be present depending on the year of manufacture. These subtleties don't usually affect functionality but contribute to the revolver's collectibility and value.
Identifying Your Ruger Single Six .22 Magnum Cylinder
To accurately identify your .22 Magnum cylinder, focus on these key areas:
1. Caliber Markings
The most reliable method is to check for clear caliber markings stamped on the cylinder itself. Look for ".22 WMR," ".22 Magnum," or a similar designation. This marking is usually found on the cylinder's side or rear.
2. Chamber Dimensions
Carefully inspect the chambers. A .22 Magnum cylinder will have larger chambers to accommodate the longer, more powerful cartridge. While this is a less definitive method than checking for markings, comparing it to known .22 LR chambers can provide supporting evidence.
3. Visual Inspection for Compatibility
If you have both a .22 LR and a .22 Magnum cylinder, comparing them side-by-side can quickly highlight the differences in size and chamber depth.
4. Ruger Serial Number Cross-Reference
While not directly identifying the cylinder, the serial number on the revolver's frame can help determine the year of manufacture and, therefore, the likely type of cylinder originally shipped with the firearm. This information can be helpful when searching for replacement parts. This would require contacting Ruger customer support or using online resources dedicated to Ruger firearm history.
Safety Precautions
- Always verify the caliber of ammunition before loading and firing any firearm.
- Never attempt to fire ammunition in a cylinder not designed for that caliber.
- If in doubt, consult a qualified gunsmith.
This guide provides essential information for safely and accurately identifying your Ruger Single Six .22 Magnum cylinder. Remember, safety should always be your top priority when handling firearms. Incorrect identification can lead to serious consequences. If you are unsure about any aspect of cylinder identification, seek assistance from a knowledgeable gunsmith or experienced firearms professional.
