3. Forster Products 6mm Creedmoor & 6.5mm Creedmoor, GO Headspace Gauge, SAAMI Dimensioned, Rimless, Hardened Steel, Precision Ground

When I first came across the Forster Products 6mm Creedmoor & 6.5mm Creedmoor GO Headspace Gauge, I immediately recognized its critical importance for anyone serious about precision shooting and firearm safety. This tool is specifically designed to check the headspace of the popular 6mm and 6.5mm Creedmoor cartridges, which are widely used among competitive shooters and hunters alike. The fact that it is SAAMI dimensioned and built from hardened steel gives me confidence that it meets industry standards and will endure repeated use without losing accuracy.
One of the key features that stood out to me is that this gauge is made for rimless cartridges. Understanding headspace in such cartridges is crucial because it directly affects how the cartridge fits in the chamber and how the rifle’s bolt closes. The headspace is essentially the distance between the bolt face and a specific datum line on the cartridge shoulder. If this dimension is off, it can result in poor accuracy or even dangerous firearm malfunctions. Having a GO gauge that corresponds exactly to the minimum chamber dimensions ensures that my chamber is not too tight or too loose, allowing me to safely chamber and fire ammunition manufactured to SAAMI maximum specifications.
From a practical standpoint, the GO gauge is invaluable when I’m working with a newly-reamed chamber. It helps me verify that the rifle will properly accept standard ammunition without excessive headspace, which could cause case stretching or other issues. The precision machining is another aspect I truly appreciate. Forster’s use of hardened steel and precision grinding to ANSI and SAAMI tolerances, with a tolerance as tight as ±0.00015 inches, means I’m getting a highly reliable measurement tool. Plus, the NIST-certified inspection process reassures me that every gauge is verified against the highest quality standards.
What really ties everything together for me is the clear explanation of what “measuring headspace” means and why it matters. This gauge isn’t just a tool; it’s a vital safety check. Measuring the difference between the length of a standard cartridge (as represented by the gauge) and the actual chamber length in my rifle ensures that the chamber is neither too long nor too short. This directly affects not only the rifle’s accuracy but also the safety of each shot. For anyone who reloads, customizes, or simply wants to maintain their rifle properly, this GO Headspace Gauge is a smart investment that can prevent costly or dangerous issues down the line.
In summary, the Forster Products 6mm & 6.5mm Creedmoor GO Headspace Gauge is a precision-crafted, reliable tool that every serious Creedmoor shooter should consider. Its adherence to SAAMI standards, hardened steel construction, and exacting tolerances make it an indispensable part of rifle maintenance and safety verification.

I’d say it’s definitely worth adding to your gunsmithing or shooting toolkit.

Buying Guide for 6.5 Creedmoor Go No Go Gauges
Understanding the Purpose of Go No Go Gauges
When I started reloading for my 6.5 Creedmoor, I quickly realized how crucial it was to maintain consistent cartridge dimensions. Go No Go gauges help me check whether my loaded rounds meet the proper chamber specifications. The “Go” gauge confirms that the cartridge will chamber fully, while the “No Go” gauge ensures that the cartridge is not oversized and won’t cause pressure issues.
Key Features to Consider
In choosing a Go No Go gauge for my 6.5 Creedmoor, I looked closely at build quality. The gauges need to be made from durable materials like steel to withstand repeated use. I also paid attention to the finish and machining accuracy, as these affect the gauge’s reliability. Another factor was whether the gauges came as a set or individually, since having both “Go” and “No Go” gauges is essential.
Compatibility with Your Chamber
One thing I found important was ensuring the gauges matched the chamber specifications of my rifle. Different manufacturers can have slight variations in chamber dimensions, so I checked the gauge specifications carefully. Some gauges are designed to SAE or CIP standards, so verifying compatibility helps avoid readings during inspection.
Ease of Use and Maintenance
I wanted gauges that were straightforward to use and easy to clean. Since these tools come into contact with powder residues and lubricants, I look for gauges with smooth finishes that don’t trap debris. Also, compact and well-marked gauges make the go/no-go process faster and less prone to error.
Price and Value
While price was a consideration for me, I didn’t want to sacrifice quality for cost. Investing in a reliable set of Go No Go gauges pays off by helping me avoid dangerous overpressure loads or feeding issues. I balanced affordability with proven durability and customer feedback to find the best value.
Final Thoughts
Using Go No Go gauges for my 6.5 Creedmoor rounds is an important step in safe and accurate reloading. By focusing on build quality, compatibility, and ease of use, I ensured that my gauges would give consistent results. Taking the time to select the right gauges has improved my confidence in every shot.
