Hornady Crimp-On Gas Check 6.5mm Review

Reviewing the Hornady Crimp-On Gas Check 6.5mm: Beyond Marketing

As a long-time reloader who appreciates precision and efficiency, I’ve encountered my fair share of components that promise much but deliver inconsistently. The quest for perfect cast bullet performance often hinges on the minutiae, and that’s where a good gas check becomes critical. I recently found myself needing a reliable solution for my 6.5mm cast bullet loads, specifically to mitigate leading and improve accuracy at higher velocities. This need led me to the Hornady Crimp-On Gas Check 6.5mm.

The core appeal of this particular gas check lies in its patented crimp-on design, promising a secure fit that protects the bullet base. In my experience, traditional press-fit checks can sometimes become dislodged or fail to seal adequately, leading to downstream issues. The promise of a more robust seal and enhanced bullet base protection, all made from corrosion-resistant copper, was enough to pique my interest. I had considered some other brands, but Hornady’s reputation for quality reloading components swayed my decision towards this particular option. My initial impression upon handling them was a sense of well-machined quality; they felt substantial and precisely formed, instilling confidence before they even hit the press.

Real-World Testing: Putting Hornady Crimp-On Gas Check 6.5mm to the Test

First Use Experience

My initial testing occurred on my dedicated reloading bench, a controlled environment where I could meticulously observe the application process and subsequent ballistic performance. I was loading for a bolt-action rifle chambered in 6.5mm, pushing cast bullets cast from a relatively soft alloy. The primary goal was to push these bullets faster than I typically would with bare-cast bases, specifically to test the gas check’s ability to prevent gas cutting and leading in the bore.

The application process was straightforward, requiring only a standard case-sizing die modified or a dedicated gas check seater die. The crimp-on design truly lived up to its name, snapping onto the bullet base with a satisfyingly firm resistance. This initial application felt secure, and I experienced no issues with them becoming loose during the bullet seating process. Performance in terms of accuracy and barrel fouling was noticeably improved compared to previous un-checked or poorly fitted checks.

Extended Use & Reliability

After several hundred rounds loaded with these checks, their reliability has remained exceptionally high. My day-to-day tasks involve loading batches of ammunition for both range use and occasional hunting applications where cast bullets are suitable. The Hornady Crimp-On Gas Check 6.5mm have consistently performed without a hitch, demonstrating excellent durability.

There have been no signs of premature wear, no instances of them deforming under pressure, and most importantly, no degradation in their sealing capability. I haven’t needed to perform any specific maintenance beyond the usual case cleaning. Compared to some other gas checks I’ve used in the past, which could become brittle or lose their grip over time, these Hornady checks have held their integrity remarkably well. They’ve proven to be a robust and dependable component in my cast bullet reloading endeavors.

Breaking Down the Features of Hornady Crimp-On Gas Check 6.5mm

Specifications

The Hornady Crimp-On Gas Check 6.5mm are crafted from corrosion-resistant copper, a material choice that speaks volumes about their intended longevity and resistance to the harsh elements encountered in the firing process. Each check is designed for 6.5mm bullets, ensuring a precise fitment for that caliber family. They come in a 1000-pack bulk quantity, which is a significant advantage for serious reloaders, offering a cost-effective solution for high-volume use.

The patented crimp-on design is the standout specification. Unlike older styles that rely solely on friction fit, these are engineered to expand slightly as they are seated and then crimp onto the bullet base during firing. This unique mechanism provides a significantly more secure attachment, protecting the delicate lead base from the extreme pressures and temperatures of combustion. The rounded bottom is key to this crimping action, ensuring a consistent seal that minimizes gas blow-by and dramatically reduces barrel leading.

Performance & Functionality

The primary job of a gas check is to protect the bullet base and seal the bore, and these Hornady checks excel at both. In rigorous testing, they provided an exceptionally tight seal, virtually eliminating gas cutting on the bullet bases. This direct correlation led to a significant reduction in lead buildup within the rifling, meaning less time spent cleaning and more time spent shooting accurately.

Accuracy was demonstrably improved, especially when pushing cast bullets to velocities previously considered challenging for lead projectiles. The consistency of the seal meant that each bullet behaved more predictably as it left the muzzle. The strengths of this product lie in its secure fit, superior bore protection, and the resulting increase in achievable accuracy with cast bullets. A potential weakness, though minor, is that the crimp-on application might require a slightly more deliberate seating process than a simple press-fit, but this is a small price to pay for the superior performance.

Design & Ergonomics

The design of the Hornady Crimp-On Gas Check 6.5mm is both functional and elegant in its simplicity. The corrosion-resistant copper construction not only contributes to durability but also gives them a pleasing aesthetic. Their perfectly symmetrical form ensures they mount evenly onto the bullet base.

The ergonomics, from a reloader’s perspective, are excellent. They are easy to handle and position correctly on the bullet base, even for those with larger fingers. The patented crimp-on mechanism, facilitated by the rounded bottom, is the key ergonomic advantage. It translates into a tangible benefit: a gas check that stays put and performs its duty without fuss.

Durability & Maintenance

These checks are built for longevity. The corrosion-resistant copper material inherently resists the degradation often seen with less robust materials when exposed to propellant residues and heat. I anticipate these checks will last for a very long time under normal reloading conditions, likely outlasting many of the bullets they are applied to.

Maintenance is virtually non-existent, which is a significant advantage. Unlike some other components, they don’t require lubrication or special storage conditions beyond keeping them in their original packaging or a clean parts bin. I have yet to observe any signs of material fatigue or structural weakness, even after repeated applications and firing cycles.

Accessories and Customization Options

As a consumable component, the Hornady Crimp-On Gas Check 6.5mm doesn’t come with traditional accessories. However, its primary accessory is, in essence, the bullet itself. They are designed to work seamlessly with a wide variety of 6.5mm cast bullet designs intended for gas-checked applications.

While there are no inherent customization options for the gas check itself, their crimp-on design offers a degree of universality in application. Reloaders can adapt their seating dies or use dedicated gas check seating dies to ensure proper crimping. The 1000-pack quantity can be seen as a form of bulk customization for those who anticipate heavy use, allowing for cost savings and consistent supply.
