- 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.
Frequently Asked Questions
What calibers does the comparator kit support?
The kit includes 14 inserts covering bullet diameters from .172 to .458, supporting popular calibers like .223, .243, .308, .338, and .45. Six headspace bushings cover sizes from A.330 to E.420 and F.188.
Why should I measure from the ogive instead of the bullet tip?
Bullet tips vary in shape and can differ by up to .025" between rounds. Measuring from the ogive (the curved portion that contacts the rifling) gives consistent cartridge base-to-ogive (CBTO) readings, which directly affect accuracy and chamber fit.
How does the headspace gauge comparator improve reloading safety?
By measuring headspace on fired and resized brass, you can verify that cases are properly sized for your chamber. This prevents excessive headspace that can cause case separation, and ensures reliable feeding and extraction.
Is the comparator compatible with my existing calipers?
Yes. The dual-screw comparator body attaches securely to standard caliper jaws, eliminating the need for a third hand. It works with most digital and dial calipers commonly used in reloading.
How do I identify the correct insert for my caliber?
Each insert is color-coded with a ceramic-like hard anodic finish and clearly marked with its diameter. The included tin storage case keeps all 14 inserts and 6 bushings organized for quick identification.
