# AltitudeCraft Bullet Comparator Kit: The Ultimate Precision Reloading Tool for Accuracy Enthusiasts (Updated June 2023) ## Introduction: Why Precision Matters in Reloading For serious shooters and reloaders, there's a world of difference between acceptable ammunition and truly precise loads. Whether you're a competitive marksman, a dedicated hunter, or simply someone who appreciates accuracy, understanding and controlling the exact dimensions of your ammunition is crucial. The difference between good and exceptional accuracy often comes down to consistency in your ammunition, particularly in bullet seating depth. Traditional measuring methods using calipers to measure overall length (OAL) can be problematic because bullets vary in shape, especially with soft points or polymer tips. Even factory ammunition with identical OAL measurements can perform differently when fired. This is where the AltitudeCraft Bullet Comparator Kit shines. It's designed specifically to address the need for precision in reloading by enabling measurements from the bullet ogive rather than the tip, ensuring better consistency and ultimately improved accuracy.

Why Precision Matters in Reloading

When it comes to reloading ammunition, precision isn't just a luxury—it's an absolute necessity. Every variable in the reloading process affects how your ammunition performs, from powder charge to primer selection. However, one of the most critical yet often overlooked factors is bullet seating depth. ### The Problem with Traditional Measurements For decades, reloaders have relied on measuring the overall length (OAL) of their ammunition. This method has a significant flaw: it measures to the tip of the bullet, which can vary considerably between manufacturers and even within the same box of bullets. As Amazon reviewer Scott T. explains: "Soft point bullets and tipped bullets vary in length by enough to throw you off if you only use OAL." This inconsistency leads to several problems: 1. **Inconsistent bullet jump** - The distance a bullet travels before engaging rifling directly impacts accuracy 2. **Potential pressure issues** - Improper seating can lead to dangerous pressure spikes 3. **Unreliable data** - Reloading recipes become difficult to reproduce consistently 4. **Wasted components** - Time and materials spent chasing inconsistent results ### The CBTO Advantage (Cartridge Base To Ogive) The solution lies in measuring from the cartridge base to the bullet ogive (CBTO). The ogive is the curved portion of the bullet that first engages the rifling of your barrel. Since this engagement point determines how the bullet begins its journey down the barrel, it's far more relevant than overall length. As reviewer Rsscully notes: "This comparator kit allows you to take a measurement length from the end of the case to the Ogive. This gives a much more consistent reading and allows you to 'compare' one loaded round to the next. My measurements are much more consistent and I feel better about my repeatability on the finished product." The AltitudeCraft Bullet Comparator Kit provides exactly this capability, serving as an essential bridge between casual reloading and precision ammunition crafting.

Key Features & Build Quality

The ultimate value of a reloading tool lies in its precision, durability, and ease of use. The AltitudeCraft Bullet Comparator Kit excels in all three areas, making it a standout choice for both novice and experienced reloaders. ### Premium Materials & Construction The AltitudeCraft Bullet Comparator is crafted from 6061 aluminum, a high-grade alloy known for its excellent strength-to-weight ratio and corrosion resistance. This material choice strikes the perfect balance between durability and practicality. Key construction features include: 1. **Hard anodic finish** - The inserts feature a ceramic-like hard anodic coating that protects against wear and provides excellent surface hardness 2. **Precision machining** - The inserts are typically machined to within .003"-.005" under nominal bullet diameter, providing the perfect fit for accurate measurements 3. **Brass thumb screws** - These provide secure attachment to calipers without marring their surfaces 4. **Clear caliber markings** - Each insert is clearly labeled with its size, eliminating guesswork As reviewer Cody W. Colvin, who compared the machining tolerances, notes: "This kit is definitely a keeper. The storage case is fairly basic sheet metal with a nice foam insert. The tool adapter is a nice anodized piece with brass thumb screws, and the bushings are all nicely anodized/labeled." ### Innovative Design Elements The AltitudeCraft kit incorporates several design features that enhance both functionality and user experience: #### Dual-Screw Design Unlike simpler comparators that may use a single attachment point, the dual-screw design ensures the comparator stays perfectly aligned with your calipers, crucial for consistent measurements. #### Color-Coded System The inserts follow a logical color-coding system that groups calibers by size range, making selection faster and more intuitive, especially when working with multiple calibers. #### Custom Foam Interior The storage tin features custom-cut foam that holds each component securely in place, preventing damage during transport and storage. This seemingly small detail was mentioned positively by numerous reviewers. As Range Squirrel explains: "I chose this over the Hornady Headspace Comparator solely on the packaging. The design is dead nuts simple and it comes in a nice metal storage box with foam cut-outs to keep things in place." ### Practical Storage Solution While functionality is paramount, the storage solution deserves special mention. The metal tin case has emerged as one of the most appreciated features among users, particularly those who have experience with other comparator systems. Reviewer H. J. Seeley comments: "I had to get a new set of comparators because I keep losing my Hornady inserts. This set is really nice because of that box that keeps everything organized in one place. It's such a great idea rather than Hornady's cheap blister pack."

How It Improves Your Reloading Process

Understanding what the AltitudeCraft Bullet Comparator Kit can do for your reloading workflow helps justify its place in your tool arsenal. Let's examine the specific ways this tool transforms the reloading process and directly contributes to better ammunition performance. ### Eliminating the Guesswork in Bullet Seating The primary function of the bullet comparator is to provide consistent measurements to the bullet's ogive rather than its tip. This seemingly simple capability has profound effects on your reloading process: 1. **Precise bullet jump control** - By measuring from the ogive, you can precisely control the distance between the bullet and the rifling (bullet jump), a critical factor in accuracy 2. **Batch consistency** - Ensure every round in a batch has identical seating depth 3. **Recipe replication** - Record exact measurements that can be replicated in future loading sessions 4. **Troubleshooting capability** - Identify inconsistencies when diagnosing accuracy issues As reviewer Brandon explains: "This kit allows for consistent measurement of all common caliber loaded rounds to ensure consistent seating depth. Using a known-good or dummy cartridge as a control, verifying seating depth is quite easy as the calipers now measure from the base to a consistent circular point around the ogive. If seated too shallow or too deep, it's easy to tell instead of 'eyeball guessing.'" ### Practical Applications Across Shooting Disciplines The benefits of using a bullet comparator extend to various shooting disciplines, each with its own requirements: #### For Competitive Shooters Competitive shooters often find that specific bullet jump distances produce the best results in their firearms. The AltitudeCraft comparator allows them to find and consistently reproduce these optimal measurements. #### For Hunters Hunters seeking the most effective terminal ballistics can use the comparator to ensure their hunting loads are consistently assembled to the exact specifications that provide the best field accuracy. #### For Long-Range Shooters Long-range precision demands the utmost consistency. As reviewer Michael Turner notes: "Consistent length is key for accuracy. The jump from the bullet to the lands can add instability to a shot and cause a bullet to tumble or spin wrong. By ensuring all loads are exactly the same length you can ensure they are all going to act the same."

So don't worry if it doesn't carry the Hornady, RCBS, Dillon, etc name, it simply won't matter." ### Real-World Performance The practical improvements noted by users highlight the tangible benefits: 1. **Improved shot consistency** - Multiple users report tighter groups after implementing the comparator in their workflow 2. **Better quality control** - Users can quickly identify and correct seating depth variations 3. **Enhanced load development** - The ability to precisely adjust seating depth helps in finding optimal loads faster 4. **Organization benefits** - The storage case keeps everything together, unlike competing systems

FAQs About Bullet Comparator Kits

### What exactly does a bullet comparator measure? A bullet comparator measures the distance from the base of a cartridge case to the ogive of the bullet (the curved portion that first engages the rifling). This measurement is more consistent and relevant than overall length (OAL) because it measures to the functional part of the bullet that interacts with the barrel rather than the tip, which can vary in shape. ### Why is measuring from the ogive better than measuring overall length? Measuring from the ogive provides more consistent data because bullet tips vary in shape and length, even within the same box. The ogive is the portion that engages the rifling, directly affecting accuracy. This method eliminates variations caused by different bullet tip designs and provides the true functional length of the cartridge. ### How does the AltitudeCraft comparator differ from more expensive brands? The AltitudeCraft comparator offers comparable performance to premium brands at a lower price point. The main differences are that it uses aluminum instead of stainless steel (which is sufficient for most users) and comes with a comprehensive set of 14 inserts in a storage case, while some premium brands sell inserts separately. In terms of measurement accuracy, multiple users report the AltitudeCraft performs on par with more expensive options. ### Do I need a special caliper to use this comparator kit? No, the AltitudeCraft Bullet Comparator Kit is designed to work with standard digital or dial calipers. The comparator body attaches to the blade of the caliper using brass thumbscrews, making it compatible with most common calipers. No special tools are required beyond the Allen wrench that comes with the kit. ### How much can bullet seating depth affect accuracy? Bullet seating depth can dramatically affect accuracy. Changes as small as .005" (five thousandths of an inch) can be the difference between exceptional and poor accuracy. This is because seating depth directly influences bullet jump (the distance a bullet travels before engaging the rifling), pressure development, and how concentrically the bullet enters the rifling. For precision shooting, consistent and optimal seating depth is crucial. ### Can I use this comparator to check factory ammunition? Yes, the comparator works equally well for checking the consistency of factory ammunition. This can be valuable for competitive shooters who want to select the most consistent factory rounds, or for reloaders who want to match the dimensions of factory ammunition that performs well in their firearms.
