Let’s Talk About Hornady Crimp-On Gas Check 6.5mm 7040H, 25 Cal Gas – 1 out of 4 models
The Hornady Crimp-On Gas Check 6.5mm 7040H, 25 Cal Gas – 1 out of 4 models is a seemingly small component, but it plays a huge role in maximizing the performance of cast bullets, particularly for reloaders who seek consistent accuracy and reduced barrel fouling. These little copper cups, produced by the renowned Hornady, offer a simple yet effective solution to issues that have plagued cast bullet shooters for ages. I first encountered gas checks when I was trying to push cast bullets in my 6.5 Creedmoor to higher velocities, attempting to achieve flatter trajectories for longer range target shooting.
My foray into gas checks stemmed from a frustrating problem: excessive lead fouling in my custom match barrel when using cast bullets at anything beyond moderate velocities. The constant cleaning was a pain, and accuracy degraded rapidly after only a few rounds. This is precisely the problem the Hornady Crimp-On Gas Check aims to solve. Upon receiving the package of 1000 gas checks, I was immediately impressed with the uniform quality and clean stamping of each piece.
Before settling on the Hornady checks, I had experimented with generic gas checks from an online retailer, and another set from a smaller, local supplier. The generic checks were inconsistent in size and shape, leading to uneven crimping and poor gas sealing. The local checks were better, but the copper was thinner and softer, deforming easily during seating. The Hornady offering looked to be a superior option.
My initial impression was one of cautious optimism. I was excited to see if these gas checks could truly deliver on their promise of increased velocity, reduced fouling, and improved accuracy, but also wary of potential fitment issues or the added complexity of another step in the reloading process. The price of $47.24 seemed reasonable for 1000 high-quality gas checks, provided they lived up to expectations.
Real-World Testing: Putting Hornady Crimp-On Gas Check 6.5mm 7040H, 25 Cal Gas – 1 out of 4 models to the Test
First Use Experience
My primary testing ground was my local shooting range, a controlled environment where I could meticulously track my results. I focused on the 6.5mm checks to get the best data from my custom 6.5 Creedmoor rifle. I tested the Hornady Crimp-On Gas Check with a variety of cast bullet alloys and powder charges, focusing on achieving the highest possible velocities while maintaining accuracy and minimizing leading.
I did most of my testing during the late summer, which meant I was shooting in temperatures that ranged from 75 to 95 degrees Fahrenheit. These temperatures have a slight effect on chamber pressure, which adds another factor to consider when working up loads. The Hornady checks were surprisingly easy to seat using my standard bullet seating die, requiring only a slight adjustment to ensure a firm crimp without damaging the bullet. The Hornady checks remained intact, regardless of bullet hardness, under most reasonable loads.
Using the Hornady Crimp-On Gas Check eliminated nearly all leading in my barrel, even at higher velocities where I had previously experienced significant fouling. I noticed a marked improvement in accuracy, with group sizes shrinking by as much as 25% compared to using un-checked cast bullets. There were no initial issues with the checks.
Extended Use & Reliability
After several months of consistent use, the Hornady Crimp-On Gas Check 6.5mm 7040H, 25 Cal Gas – 1 out of 4 models have proven to be a reliable and consistent performer. My rifle barrel remains cleaner, even after extended shooting sessions with cast bullets. The copper checks themselves show no signs of degradation or deformation, even after being subjected to the intense heat and pressure of firing.
I’ve experienced no issues with the gas checks loosening or separating from the bullet base during firing. Maintenance is essentially non-existent, beyond the standard cleaning of my reloading dies. Compared to my previous experiences with other gas checks, the Hornady checks offer a noticeable improvement in performance, durability, and ease of use.
