The .223 Wylde chamber is gaining popularity among AR-15 builders and shooters. Its versatility and accuracy make it a compelling choice, but ensuring proper chamber dimensions is crucial for reliable function and optimal performance. This is where the 223 Wylde Go/No-Go gauge comes in. This guide will delve into the intricacies of the .223 Wylde chamber, the importance of gauging, and how to use a Go/No-Go gauge effectively.
Understanding the .223 Wylde Chamber
The .223 Wylde chamber is a hybrid design, combining the best features of the 5.56 NATO and .223 Remington chambers. Unlike its predecessors, the .223 Wylde is designed to reliably fire both 5.56 NATO and .223 Remington ammunition without compromising accuracy or safety. This versatility is a significant advantage for shooters who want to use readily available ammunition without sacrificing performance.
Key Differences from .223 Remington and 5.56 NATO
| Feature | .223 Remington | 5.56 NATO | .223 Wylde |
|---|---|---|---|
| Chamber Dimensions | Smaller, tighter | Larger, more generous | Compromise between both |
| Pressure | Lower | Higher | Handles both safely |
| Ammunition | .223 Remington only | 5.56 NATO only | Both .223 & 5.56 |
| Accuracy | Potentially higher with .223 ammo | Can be less accurate with .223 ammo | High accuracy with both |
The .223 Wylde's slightly larger chamber allows for reliable feeding and extraction of both cartridge types, while maintaining sufficient pressure control to prevent excessive wear or damage. The longer leade (the portion of the chamber where the bullet starts its travel) promotes better bullet stabilization and accuracy, especially with heavier projectiles commonly used in precision shooting.
The Importance of Gauging Your .223 Wylde Barrel
A properly chambered barrel is essential for safe and reliable operation. A .223 Wylde Go/No-Go gauge allows for precise measurement and verification of the chamber's dimensions, ensuring it conforms to specifications. Using a gauge is critical because:
- Safety: An improperly sized chamber can lead to dangerous pressure spikes, potentially resulting in catastrophic barrel failure.
- Accuracy: Variations in chamber dimensions can directly affect accuracy, leading to inconsistent groupings and poor shot placement.
- Reliability: A correctly sized chamber guarantees reliable feeding, extraction, and ejection of cartridges.
How to Use a .223 Wylde Go/No-Go Gauge
The gauge typically consists of two separate components: a "Go" gauge and a "No-Go" gauge.
-
Go Gauge: This gauge represents the minimum acceptable chamber dimensions. It should smoothly enter the chamber with minimal resistance. If it doesn't, the chamber is too tight.
-
No-Go Gauge: This gauge represents the maximum acceptable chamber dimensions. It should not fully enter the chamber. If it does, the chamber is too large.
Procedure:
-
Clean the Barrel: Ensure the barrel is thoroughly cleaned and free of debris before gauging.
-
Insert the "Go" Gauge: Gently insert the "Go" gauge into the chamber. It should slide in easily. If it's tight or difficult, the chamber may be too small.
-
Insert the "No-Go" Gauge: Attempt to insert the "No-Go" gauge. It should not enter completely. If it goes in fully, the chamber is too large.
Case Study: A Barrel with Out-of-Spec Chamber
A gunsmith recently encountered a barrel with a chamber significantly larger than specifications. Upon gauging, the "No-Go" gauge easily entered and even passed completely into the chamber. This indicated a large variance from the manufacturer’s specifications. As a result, the gunsmith deemed this barrel unsafe for firing with any ammunition and recommended replacement.
Choosing the Right Gauge
Make sure to buy a gauge specifically designed for the .223 Wylde chamber. Using an incorrect gauge will lead to inaccurate measurements and potentially unsafe results. Reputable manufacturers such as Clymer, Wheeler Engineering, and others offer high-quality gauges.
Conclusion
The .223 Wylde chamber offers a unique combination of versatility and accuracy. However, utilizing a .223 Wylde Go/No-Go gauge is paramount for ensuring safety, optimal performance, and reliable function. By properly using a gauge, builders and shooters can confirm that their barrels are within acceptable dimensions, minimizing the risk of issues and maximizing their shooting experience. Remember, a properly gauged chamber is an investment in safety and accuracy.
