When it comes to building accurate, consistent ammo, neck tension matters. That’s why we created the Forster Neck Tension Gage (NTG)—an inspection tool that gives reloaders a fast, reliable way to measure inside neck diameter after sizing and before bullet seating.
Whether you’re working up a new load or verifying your process, the NTG gives you real insight into neck tension—without guessing.
What Does the NTG Do?
- Measures the inside neck diameter of your sized brass with precision
- Helps you achieve consistent bullet release for tighter groups
- Detects potential issues like neck-shoulder donuts that can interfere with seating depth
- Speeds up batch inspection so you can catch variation before it impacts performance
Don’t let the size fool you—this little tool pulls its weight. It’s an excellent addition to your case prep and inspection process—especially if you’re chasing maximum consistency from round to round. If you have any questions about neck tension gages, feel free to give us a call!
