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

About This

• 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.
• 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.

• Bullet and Headspace Comparator Kit
• Our tools are built from the bench up. Instead of random single pieces, we design complete, color-coded kits in metal cases with clear markings and caliber charts. You get match-grade machining, smart organization, and big-brand performance without the big-brand price.
• Reloaders are tired of inconsistent measurements, missing inserts, and vague instructions that waste time and components. Our kits bring everything together, making ogive and headspace checks simple, repeatable, and reliable across multiple rifles.
• Achieve repeatable, match-grade measurements for bullet seating depth and shoulder bump. This complete comparator kit measures from the ogive and the case datum, eliminating inconsistencies from tip variations or worn brass. Built for reloaders who demand accuracy and reliability.
• Measure bullet seating depth from the ogive and set precise shoulder bump using the same comparator body. This kit delivers consistent, repeatable results for both bullet and brass measurements, helping reloaders fine-tune chamber fit, improve accuracy, and eliminate guesswork.
• Cover nearly every common rifle and hunting cartridge with 14 bullet inserts and 6 headspace bushings. Each piece is clearly labeled for fast caliber selection, helping reloaders achieve precise seating depth and shoulder bump control across multiple platforms.
• This set includes six precision-machined headspace bushings sized from A.330 to E.420. Each bushing measures the case shoulder datum for reliable shoulder bump control. Compatible with a wide range of rifle chambers, ensuring consistent sizing and safer, more accurate reloads.
• Will this bullet and headspace comparator kit work with both bullet seating depth and headspace measurements?
• Yes. The kit includes 14 bullet inserts for ogive-to-base seating depth measurements and 6 headspace bushings for case shoulder datum measurements. You can measure both seating depth consistency and shoulder bump with the same comparator body.
• Are the inserts and bushings compatible with all digital and analog calipers?
• Yes. The comparator body is designed to fit almost all calipers from major brands. The brass thumb screws allow tool-free tightening, and the aluminum body will not scratch or damage the caliper jaws during installation.
• How do I know which insert or bushing size fits my caliber?
• Each insert and bushing is laser-etched and color-coded for quick identification. The product listing and included chart show the correct match for bullet diameters and shoulder datum sizes, making selection fast and confusion-free.
• Can this kit improve the accuracy and consistency of my reloads?
• Yes. Measuring from the ogive eliminates tip-length variation, and measuring from the shoulder datum ensures consistent shoulder bump. These two measurements help you produce more uniform cartridges, improving accuracy and chamber fit.
• Will the laser-etched markings fade or wear off with regular use?
• No. All inserts and bushings use permanent laser engraving and a hard-anodized finish. The markings are resistant to wear, corrosion, and solvents, ensuring they remain readable even after long-term reloading use.
