Forster Neck Tension Gage NTG-224
Precision inspection tool for .224 caliber brass. Four stepped diameters help you measure inside neck diameter and optimize bullet seating tension for consistent, accurate reloads.
Forster Neck Tension Gage: Essential Brass Inspection
The Neck Tension Gage is a straightforward but indispensable tool for serious reloaders. It allows you to measure the inside diameter of your case necks with precision, ensuring that your ammunition performs consistently from round to round.
How It Works
After you've sized your brass and before you seat your bullets, insert the stepped end of the gage into the case neck. The tool features four incrementally larger diameters, each clearly etched with its measurement. Slide the gage in until one diameter achieves a slip fit—that's your inside neck diameter.
Why Neck Tension Matters
Consistent bullet release depends on proper neck tension. Too tight, and you risk excessive pressure and inconsistent velocities. Too loose, and bullets may shift during handling or firing. This gage helps you find the sweet spot for your specific brass and bullets.
What You'll Detect
- Inside neck diameter variations across your batch
- Donuts (excess material buildup at the neck-shoulder junction) that can compromise accuracy
- Brass that needs additional prep work before seating
The Forster Advantage
Forster reloading tools are built for precision and durability. This gage is no exception—a simple, effective solution that takes the guesswork out of neck preparation and helps you produce ammunition worthy of your rifle's accuracy potential.
