My Buying Guides on 308 Go No Go Gauge
When I first started reloading and inspecting my .308 brass, I quickly realized the importance of having a reliable Go No Go gauge. It’s an essential tool that helps me ensure my cartridges are within safe and functional dimensions. If you’re like me and want to make sure your ammo is spot on, here’s what I’ve learned about choosing the right 308 Go No Go gauge.
Understanding What a 308 Go No Go Gauge Is
Before diving into buying one, I made sure I understood what this gauge does. A 308 Go No Go gauge checks the headspace of your .308 Winchester cartridges. The “Go” side confirms that the cartridge fits within the maximum allowable chamber length, while the “No Go” side helps detect if the cartridge is too long or could cause dangerous pressure issues. This dual-check system is crucial for safety and reliability.
Why I Needed a Go No Go Gauge for .308
Reloading can be tricky, and with the .308 Winchester being such a popular cartridge, I wanted to avoid any guesswork. Using the gauge helps me:
- Prevent overpressure situations by catching cases that are too long.
- Extend brass life by knowing when to trim or replace.
- Ensure consistent chambering and feeding in my rifle.
Key Features I Looked for When Buying
- Durability and Material
I chose a gauge made from hardened steel because it withstands regular use without deforming. Some cheaper models use aluminum, but they don’t last as long.
- Precision and Accuracy
The gauge must be machined to exact dimensions. I checked reviews to confirm the gauge was reliable and matched SAAMI specs for .308 Winchester.
- Clear Markings and Easy Use
I appreciate gauges with clearly labeled “Go” and “No Go” sides and a comfortable design that fits well in my hands. This makes quick inspections easier.
- Compatibility
Since there are slight variations in chamber dimensions between manufacturers, I looked for a gauge that is compatible with my rifle’s chamber or one that meets standard SAAMI specifications.
My Buying Tips
- Buy from Reputable Brands: I went with well-known manufacturers like Hornady or RCBS because their gauges come with warranties and reliable customer support.
- Consider Your Reloading Frequency: If you reload often, invest in a higher-quality gauge. For occasional use, a more affordable option might suffice.
- Check for Calibration Certificates: Some premium gauges come with certificates to confirm their accuracy, which gave me added confidence.
- Read User Reviews: Real user experiences helped me avoid gauges that had issues like poor machining or durability problems.
How I Use My 308 Go No Go Gauge
I insert the cartridge case into the “Go” side first—if it fits smoothly, it passes the minimum dimension test. Then, I try the “No Go” side; if the case fits here, it means the headspace is excessive, and I need to trim or retire the brass. This simple process has saved me from potential firearm damage and unsafe reloads.
Final Thoughts
Getting a good 308 Go No Go gauge was one of the best decisions I made in my reloading journey. It’s a small investment that ensures safety, accuracy, and longevity of my brass. If you’re serious about your .308 reloads, I highly recommend adding this tool to your kit. Just remember to pick one that suits your needs and budget, and you’ll be set for many safe reloads ahead.
