Hornady Lock-N-Load Bullet Comparator Basic Set, Includes 7 Bullet Inserts – Quickly and Precisely Measure Loaded Rounds, Measures from Bullet Ogive – Reduce Round Variations – B234

Hornady Comparator Kit – The Hornady Lock-N-Load Bullet Comparator is perfect for the reloader looking to measure seating depth of loaded ammunition quickly and precisely. Measures from the bullet ogive to the base of the loaded round, to eliminate variation in seating depth. This basic set includes 7 bullet inserts
Why Do You Need a Hornady Bullet Comparator – Measuring cartridge lengths across the bullet tips is not a reliable (or repeatable) method for measuring loaded rounds. It’s common for variations of up to .025” to exist from one round to the next
Reliable Rounds – Our Bullet Comparator measures rounds from the ogive to provide consistent, precise measurements. You can also use it to check uniformity of bullets from base to ogive
Easy Measuring – Our Bullet Comparator easily attaches to the blade of your caliper and uses interchangeable inserts (available in sizes from .17 caliber to .45 caliber) to measure from the bullet ogive
Kit Includes – Comparator body and 7 comparator inserts for the following diameter bullets: 224, 243, 257, 264, 277, 284 and 308. Allen Wrench also included. Other inserts sold separately. To position the comparator with the Hornady Lock-N-Load Overall Length Gauge, install comparator body to the caliper with the screw through the thicker leg of the body. This allows the proper off center alignment of the Length Gauge

AltitudeCraft Bullet and Headspace Gauge Comparator Kit with 14 Inserts and 6 Bushings, Reloading Supplies and Equipment and Ammo Reloading Tool with Tin Box, Anodized Aluminum

Ultimate Precision for Every Caliber: The AltitudeCraft bullet and headspace gauge comparator kit is designed to cater to a wide range of calibers from .17" to .45" and headspace sizes up to E420. With 14 inserts and 6 bushings, this comparator reloading kit eliminates guesswork, allowing reloaders to precisely measure both bullet seating depth and headspace, essential for optimal shooting performance.
Ensure Consistency: Measuring cartridge lengths at the bullet tips is unreliable and often varies by up to .025” between rounds. The bullet comparator measuring tool equipment provides consistent and precise measurements by measuring from the ogive, allowing for checks on bullet uniformity from base to ogive. The headspace gauge comparator kit enhances safety, improves accuracy, and extends the life of brass.
Innovative Design for Enhanced Accuracy: The dual-screw design of the bullet comparator body enables seamless connection to your caliper blade, eliminating the need for a third hand to obtain accurate measurements. Inserts are color-coded and feature a ceramic-like hard anodic finish for enhanced durability, simplifying identification and increasing longevity.
Engineered for Durability and Ease of Use: Crafted from high-quality 6061 aluminum, the bullet and headspace gauge comparator measuring tool ensures longevity and reliability. A sturdy tin case securely holds all components, offering protection and easy storage.
What's Included in the Comparator Reloading Set: The kit includes the comparator body, 14 inserts for bullet diameters 172, 204, 224, 243, 257, 264, 277, 284, 308, 338, 358, 375, 416, and 458, and 6 bushings for sizes A.330, B.350, C.375, D.400, E.420, and F.188, An Allen Wrench and a Setscrew are also included.

High Grade Bullet & Headspace Comparator Set by Derraco Engineering

Screw-on bushing design. Stainless Steel bushing holding body. Better concentricity and consistency than the H brand or others
High-grade CNC machining ensures precise, consistent, and beautifully finished parts
Color-coded bushings with a ceramic-like Type II hard anodic coating provide a durable finish and make it easy to identify calibers for user convenience
A nice tin box is included for convenient bushing storage
Headspace gauge bushings were individually pin-checked with Go=-12μm(-half thou), No-Go=+12μm(+half thou)
We're a small business from Australia called Derraco Engineering. We take our time designing and making our products, making sure we do it right without taking any shortcuts. We hope that once you try our stuff, you'll remember our name.
Our bullet comparator bushings are designed according to bore riflings. They are not supposed to be the exact size such as .2200 or.3000. Riflings ID is always a bit smaller than the bullet diameter otherwise won't form the gas seal.
Our headspace gauge bushings are in exact marked size as this was made according to SAAMI headspace gauge standards. All our bushings do not have any ID chamfer and they were not sand blasted like some others. The clean sharp edge is designed for accurate measuring of bullet and shoulder contours.
Tip for choosing headspace gauges: measure the neck OD and shoulder OD. The best measuring point should be close to the middle line of the neck OD and Shoulder OD. The middle line of the shoulder taper. Therefore you should just choose which ever headspace bushing with ID nearest to the shoulder taper's middle line diameter.
