1. 308 Winchester Headspace Gauge Set GO and NO-GO

As a passionate enthusiast of firearms and precision shooting, I understand the importance of having reliable tools that ensure the safety and performance of my rifles. That’s why I find the ‘308 Winchester Headspace Gauge Set GO and NO-GO’ particularly compelling. This product is designed to make checking headspace a straightforward and precise task, which is crucial for any serious shooter or gunsmith. The ability to accurately measure headspace ensures that my rifles are functioning optimally, ultimately enhancing my shooting experience.
One of the standout features of this gauge set is its versatility. It can be used to check the headspace of a variety of cartridges, including 243 Win., 260 Rem., 7mm-08, 308 Win., 338 Fed, and 358 Win. This means that whether I have a bolt-action rifle chambered in one of these calibers or am working on multiple rifles, this gauge set will meet my needs. The fact that it accommodates several rimless cartridges adds to its value and usability in my arsenal.
Understanding headspace is crucial for accurate shooting and safety. The ‘GO’ and ‘NO-GO’ gauges serve different purposes that I find incredibly beneficial. The ‘GO’ gauge corresponds to the minimum chamber dimensions, which means if my rifle closes on it, I can be confident it will accept ammunition made to SAAMI maximum specifications. This is essential for ensuring that my newly-reamed chamber is not only tight but also safe to fire. Conversely, the ‘NO-GO’ gauge helps me determine the maximum headspace recommended for gunsmiths when chambering new bolt-action rifles. If my rifle closes on the ‘NO-GO’ gauge, I know that I need to take further steps to ensure that my rifle has the right headspace, potentially using a FIELD gauge for a more thorough check.
Another major highlight of this product is its manufacturing quality. The gauges are precision machined from high-quality, hardened steel and ground to ANSI and SAAMI tolerances. With a headspace tolerance ground to an exacting ±.00015, I can trust that the measurements I am taking are reliable. Each headspace gauge undergoes rigorous inspection with NIST-certified measurement tools, ensuring that I am using a product that adheres to the highest standards of quality. This level of precision is something I genuinely appreciate, as it translates directly to the reliability and accuracy of my firearms.
the ‘308 Winchester Headspace Gauge Set GO and NO-GO’ is an invaluable tool for anyone serious about their shooting, whether they are a gunsmith or an avid rifle enthusiast like me. By investing in this gauge set, I am ensuring that my firearms are safe and performing at their best.

I recently came across the Forster Products NO-GO Headspace Gauge designed for various rimless cartridges such as the 243 Win, 260 Rem, 7mm-08, 308 Win, 338 Fed, and 358 Win. As an avid rifle enthusiast and someone who takes great care in ensuring my firearms operate safely and efficiently, I found this product to be an essential tool for anyone involved in rifle maintenance or gunsmithing. Let me share my thoughts on its features and how it can benefit individuals like myself.
First and foremost, the primary function of this headspace gauge is to check the headspace of several popular cartridges. This is crucial because the proper headspace ensures that the cartridge fits correctly in the chamber, allowing for safe and reliable firing. The gauge measures the distance between the bolt face and a datum line, which is determined by SAAMI standards. This precise measurement is vital for maintaining the integrity and safety of your rifle, particularly when chambering new bolt-action rifles.
The NO-GO designation of this gauge corresponds to the maximum headspace recommended for gunsmiths when chambering new rifles. What I appreciate about this feature is that if a rifle closes on the NO-GO gauge, it signals that there may be an issue with excessive headspace. While it’s important to note that this measurement is not a SAAMI-maximum, it serves as a valuable first step in diagnosing potential problems. If there are concerns about excessive headspace, utilizing a FIELD gauge provides an additional layer of assurance. This step-by-step approach to checking headspace is not only effective but also promotes safety in firearm usage.
Another highlight of the Forster Products NO-GO Headspace Gauge is its precision machining. Constructed from hardened steel and precision ground to ANSI and SAAMI tolerances, the gauge boasts a headspace tolerance ground to a very exacting ±.00015. This level of precision is essential for serious gunsmiths and hobbyists alike, as it guarantees that the gauge will deliver accurate and reliable results. Each headspace gauge undergoes thorough inspection with NIST-certified measurement tools, ensuring that I am using a high-quality product that I can trust.
In addition to its functional features, the ease of use and meaningful measurement provided by this NO-GO gauge cannot be overstated. It allows users like me to measure headspace in a way that is straightforward and effective. Understanding the difference between the standard cartridge length and my rifle’s actual chamber length is fundamental for safe shooting practices. By ensuring that the cartridge head is flush against the bolt face, I can confidently assess whether my firearm is operating within safe parameters.
Overall, I find the Forster Products NO-GO Headspace Gauge to be an indispensable tool for anyone who takes their shooting seriously. Whether I’m a gunsmith reaming new chambers or simply a rifle enthusiast looking to ensure my firearms are safe and reliable, this gauge meets my needs perfectly. With its precision, reliability, and ease of use, I highly recommend this product to anyone in the market for a headspace gauge. If you’re serious about your shooting experience and want to maintain the safety and efficiency of your rifles, investing in this gauge could be one of the best decisions you make.
