Precision Reloading with AltitudeCraft Bullet Comparator Kit

Why Every Reloader Needs a Bullet Comparator Kit

When I first started reloading, I thought measuring to the bullet tip was good enough. Boy, was I wrong. Talk about inconsistent results! The day I added a bullet comparator to my reloading tool list, my groups tightened dramatically.

But what exactly is a bullet comparator, and why is it so important to precision reloading?

A bullet comparator allows you to measure from the base of your cartridge to the bullet's ogive (the curved portion where the bullet begins to narrow toward the tip). This is the critical point that makes contact with your rifle's rifling, not the bullet tip.

The AltitudeCraft Bullet Comparator Kit solves a fundamental problem in bullet measurement: inconsistency. When you're using soft-point or polymer-tipped bullets, the tips can vary slightly in length, making traditional overall length (OAL) measurements unreliable. By measuring to the ogive, you're getting a consistent reference point.

As one reloader with 20+ years of experience put it: "Measuring to ogive to assure seating consistency is the only way to really get the accuracy you're chasing. Soft point bullets and tipped bullets vary in length by enough to throw you off if you only use OAL."

What's Included in the AltitudeCraft Bullet Comparator Kit

The AltitudeCraft kit is remarkably comprehensive, especially considering its price point. Here's what you get in the package:

• 1 anodized aluminum comparator body with dual brass thumbscrews
• 14 precision-machined caliber inserts covering: .172, .204, .224, .243, .257, .264, .277, .284, .308, .338, .358, .375, .416, and .458
• Allen wrench for adjustment
• Setscrew for secure mounting
• Metal storage tin with custom-cut foam insert
• Instruction manual

I've found the color-coding system particularly helpful when I'm working across multiple calibers in a reloading session. The smaller calibers (.17-.24) are gold/bronze, mid-range (.25-.30) are silver, and larger calibers (.33-.45) are black. This makes grabbing the right insert much quicker than having to squint at tiny markings.

The storage case is a nice touch that many competitors don't include. As one reviewer mentioned: "I already had the Hornady Bullet Comparator, a great tool, but the pieces are loose; I made my own case for them, but quality factory packaging makes a huge difference."

How the Bullet Comparator Works: A Real-World Explanation

So how do you actually use this thing? It's pretty straightforward, but there's a technique to it.

First, you attach the comparator body to your digital calipers using the brass thumbscrews. Make sure it's snug but not overtightened. Then select the appropriate insert for your bullet caliber and secure it in the comparator body.

With the tool assembled, zero your calipers with the comparator attached. Now you're ready to measure your loaded rounds from the case head to the bullet ogive.

I often start by measuring a factory round that performs well in my rifle as a baseline. Then I can adjust my seating die to match that measurement for my handloads, or experiment with different seating depths to find what works best in my particular gun.

Just remember that comparator measurements are relative, not absolute. As one experienced reloader explained: "A comparator is not an absolute. It doesn't matter what dimension the insert is because you don't use it to measure to a standardized length. You use it to establish a length for just your application."

Practical Tips for Getting the Most Accurate Measurements

• Always ensure the insert is fully seated in the comparator body
• Keep the cartridge perfectly aligned when measuring
• Take multiple measurements and average them for best results
• Use consistent pressure when taking measurements
• Create a log of your measurements for different loads and rifles

The Quality and Construction of the AltitudeCraft Kit

When I first got this kit, I was a bit skeptical about how it would compare to my Hornady tools. I'm happy to report that the quality is excellent, especially considering the price difference.

The comparator body and inserts are made from 6061 aluminum with an anodized finish. The smaller inserts have a gold/bronze finish, the mid-range are silver, and the larger ones are black. The finishes are described as "ceramic-like hard anodic" which should provide good durability.

One reloader tested the precision of the inserts and reported: "The all fall between about 0.007" and 0.009" under nominal bullet diameter. This is pretty much spot on for the calibers between .264 and .458 but its a bit much for the smaller calibers."

The brass thumbscrews provide secure attachment to your calipers without marring them. I've had no issues with slippage during use.

A few users have noted that the printed caliber markings (not engraved) can be difficult to read on the silver inserts due to low contrast. This is a minor issue but worth mentioning.

Comparing the AltitudeCraft Kit to Competitors

How does the AltitudeCraft Bullet Comparator Kit stack up against other options on the market? Let's break it down:

As one user succinctly put it: "For the price, it would be difficult to beat this bullet length comparator set." The Hornady offers fewer inserts in its basic kit, while the Sinclair is significantly more expensive (though it does offer stainless steel construction).

For most reloaders, the AltitudeCraft kit hits the sweet spot of value and functionality. You get all the calibers you're likely to need without having to buy additional inserts or accessories.

What Users Are Saying About the AltitudeCraft Bullet Comparator Kit

The feedback from actual users has been overwhelmingly positive. Here are some common themes from reviews:

• "Great value compared to name-brand alternatives"
• "Impressed with the quality and precision"
• "Storage tin is a nice touch for organization"
• "Measurements are consistent and accurate"
• "Comprehensive set covers all my reloading needs"
