Stoney Point Head Shoulders Cartridge Headspace Gauge Product Info

Measure cartridge headspace with a caliper? Absolutely! With this affordable Stoney Point Head 'n Shoulders Cartridge Headspace Gauge, it's as easy as measuring trim length.

Stoney Point Head ‘n Shoulders gauge is the best method we've found to extend brass life, improve accuracy, and enhance safety. The gauge by Stoney Point measures variations in your brass before and after firing, or re-sizing. It allows comparison between fire-formed brass and your re-sized brass. Any of five interchangeable bushings are attached to your caliper using the same Stoney-Point B-2000 body as found on Stoney Point Bullet Comparator. The five bushings that come with the Head‘n Shoulders Headspace Stoney Point Gauge set provide the ability to check most bottleneck cases, from .17 Remington through the belted magnums. Ackley Improved chambers use the same bushing size as the parent case.

Note: Many Weatherby cases may be checked by measuring cases on the inside radius and on the outside radius. Use the appropriate bushing size(s) to gauge near the center of the radius.

After attaching to your caliper with the brass thumbscrew, simply select the proper bushing to measure your cases from the case-head to the datum line on the case shoulder. Typically, when full-length re-sizing, the die should be adjusted to set the shoulder back .001" to .002". This will provide a proper (minimal) clearance with the firearm's chamber. A proper headspace will minimize case stretching, reduce work hardening, extend case life, improve accuracy, and increase safety.

For the shooter with an autoloader, check your fired cases by rotating the brass in the StoneyPoint Head ‘n Shoulders Gauge to identify cases with bent rims – a certain cause of "flyers". You can also identify excessive headspace conditions, which is a potentially dangerous situation. Proper headspace also provides proper firing pin contact with the primer to improve the reliability of your loads.
