Sinclair International Concentricity Gauge with Digital Indicator

The Sinclair Concentricity Gauge is a user-friendly and exceptionally accurate measuring device designed for the serious precision handloader. Precisely manufactured for a lifetime of use, this tool allows you to measure and correct cartridge runout, a critical factor in producing ammunition with the highest degree of accuracy. This gauge is versatile enough to accept a wide range of cartridges, from small varmint calibers all the way up to .50 BMG.

Key Features & Operation:

• High-Precision Measurement: Used to measure the runout (concentricity) of sized case necks or the bullet of a loaded cartridge, allowing the handloader to identify and sort rounds for improved accuracy.
• Dual Bearing Block System: The cartridge is cradled and smoothly rotated on two sets of precision bearings. These bearings are housed in durable, anodized aluminum blocks that move in unison within a milled slot on the base plate.
• Fully Adjustable: The bearing blocks are longitudinally adjustable to securely support different case lengths or overall cartridge lengths. Large thumb levers make these adjustments quick and easy.
• Versatile Indicator Mount: The indicator tower is designed to allow both vertical and lateral adjustment of the digital indicator, ensuring you can position it perfectly for measurement on either the case neck or the bullet.
• Stable Platform: The heavy, anodized base plate is extremely stable, providing a solid foundation for taking precise and repeatable measurements.
• Standard Indicator Compatibility: The mounting block is designed to accommodate any dial or digital indicator with a standard 0.375" mounting stem.
