Reloading precision starts with accurate measurements, and the Hornady Lock-N-Load Bullet Comparator Basic Set is built to eliminate the guesswork that comes with measuring loaded ammunition. Rather than relying on tip-to-base cartridge length—a method prone to variation of .025" or more between rounds—this tool measures from the ogive, the curved surface of the bullet where consistency actually matters. Whether you're a precision hand-loader chasing tight groups or someone who values quality control in every round, a bullet comparator gives you the repeatable, reliable data you need.
The Lock-N-Load comparator attaches directly to your digital or dial caliper using a simple thumbscrew, turning a basic measuring tool into a specialized instrument for reloading. The interchangeable inserts included in this set accommodate seven common bullet diameters, so you can measure rounds across multiple calibers without buying separate equipment. The comparator also serves as a quality-check tool for evaluating bullet uniformity from base to ogive—essential information if you're sorting premium bullets or validating a new lot.
This is the kind of small-shop detail that separates good reloading from excellent reloading. When you're investing time and materials into ammunition, spending a few seconds to verify each round's dimension from a consistent reference point pays dividends downrange. The Hornady system is straightforward enough for beginners but robust enough for the serious hand-loader who demands consistency.

Frequently Asked Questions
What calipers work with the Hornady Lock-N-Load Bullet Comparator?
The comparator attaches to standard calipers via thumbscrew. Digital and dial calipers are both compatible, making it easy to integrate into an existing reloading setup.
What calibers can I measure with the basic set?
The set includes seven inserts covering .224, .243, .257, .277, .284, and .308 diameter bullets, plus one additional insert. If you reload outside these calibers, additional inserts are available separately.
How is measuring the ogive better than measuring cartridge length tip-to-case?
Bullet shape varies slightly from round to round, so measuring from the tip introduces variation of up to .025" or more. The ogive is a consistent reference point on the bullet itself, giving you repeatable, apples-to-apples measurements that reflect true cartridge uniformity.
Can I use the comparator to check my bullets before loading?
Yes. The Hornady comparator works well for verifying bullet uniformity from base to ogive, making it useful for sorting or QC-checking bullets before they go into your press.
