22 Caliber Bullet Comparator Insert

The 22 Caliber Bullet Comparator Insert is a precision reloading accessory manufactured by Hornady that enables shooters to measure and sort .223 and .224 caliber projectiles with exacting accuracy. Designed for serious handloaders and competitive shooters who demand consistency in ammunition assembly, this comparator insert integrates seamlessly into Hornady's bullet comparator body system to ensure uniform bullet seating depth and overall cartridge length. Proper bullet measurement is fundamental to achieving tight velocity spreads, improved accuracy, and reliable firearm function across rifles chambered in .223 Remington, 5.56 NATO, and similar .22-caliber platforms.

This comparator insert works by allowing ammunition technicians to gauge the ogive (the curved section of the bullet) rather than the tip, which can vary in shape across different bullet designs. By measuring from the ogive to the cartridge case shoulder, reloaders establish a datum line independent of bullet shape—critical for precision work where seating depth directly affects pressure, velocity, and shot-to-shot consistency. The insert's carefully engineered bore diameter accommodates the full range of .223 and .224 projectiles, from lighter varmint rounds to heavier match-grade bullets, making it an indispensable tool for both development work and production reloading.

Reloaders preparing ammunition for AR-15 rifles, bolt-action .223 platforms, or competitive shooting disciplines benefit most from this insert's precision. Competition shooters and handloaders pursuing sub-minute-of-angle accuracy will find it essential for quality control during cartridge assembly. The 22 Caliber Bullet Comparator Insert pairs with any standard Hornady comparator body, making integration into existing reloading setups straightforward. Weighing just 0.1 lbs, this compact insert stores easily in a reloading bench setup and delivers years of reliable service with proper care.
