Detailed Analysis
The Hornady GMX, or Gilding Metal eXpanding, stands out in the world of hunting ammunition as a monolithic copper alloy bullet. The GMX offers hunters a lead-free option, representing a crucial advancement in ammunition technology. For hunters in areas with lead restrictions or for those prioritizing environmental responsibility, the GMX provides excellent terminal performance without introducing lead into the environment.
The GMX’s design is engineered for maximum expansion and deep penetration. This means that when a GMX bullet strikes an animal, it’s designed to mushroom outwards, transferring a significant amount of energy to the target and creating a large wound channel. The solid copper construction also contributes to exceptional weight retention, meaning that a GMX bullet will retain nearly all of its original weight upon impact, maximizing its ability to punch through bone and tissue, leading to effective penetration.
Its design features a carefully crafted hollow point that initiates expansion and its streamlined profile is designed to maintain velocity downrange. It allows for flatter trajectories and, subsequently, a greater effective range. The monolithic design means that there is no core and jacket separation, which helps to ensure that the bullet will reliably penetrate even through the toughest of targets.
Performance Characteristics
The performance characteristics of the GMX are truly impressive. Hunters often report exceptional weight retention, typically retaining between 95% and 100% of the original bullet weight after impact. This high level of weight retention is a testament to the solid copper construction and the design’s ability to stay together during expansion. This ensures that the bullet will continue its path through the animal, causing significant internal damage, even after passing through heavy bone and muscle.
The GMX’s expansion, initiated by the hollow point, is designed to be reliable. The mushrooming effect delivers a wide wound channel, maximizing tissue damage and promoting rapid knockdown. The GMX excels in situations where deep penetration is essential. It’s an excellent choice for larger game animals and for hunters who often take shots at longer ranges where bullet velocity can be reduced.
Ideal Hunting Applications
Considering its performance, the GMX is well suited to a range of hunting applications. It’s particularly effective on larger game animals, such as elk, moose, and even bear. Hunters can also use GMX bullets on deer and antelope, provided they choose the correct caliber and bullet weight for their quarry. The GMX’s exceptional penetration capabilities make it a reliable choice, even when encountering heavy bone structure or dense muscle.
The Hornady CX: Engineered for Controlled Expansion and Devastating Results
Overview
The Hornady CX presents a different, yet equally compelling, approach to hunting bullet design. The CX, or Copper eXpanding, maintains a classic construction: a lead core, but is jacketed in a copper alloy. This blend allows for controlled expansion while maintaining the ballistic advantages offered by the core material. It represents a significant step forward for lead-core bullets, offering advanced performance in the field.
Detailed Analysis
The design of the CX incorporates advanced features to promote both expansion and penetration. The bullet is built with a copper alloy jacket and a lead core designed for a controlled opening. This creates a balance between expansion, weight retention, and penetration. The jacket is carefully engineered to peel back upon impact, while the lead core helps maintain the bullets momentum through the animal.
Performance Characteristics
The terminal ballistics of the CX are impressive. Upon impact, the bullet expands to a controlled diameter, creating a large wound channel. The lead core ensures that the bullet retains a substantial amount of its weight, allowing for effective penetration. The expansion design maximizes the energy transfer to the animal. This results in significant tissue damage and rapid knockdown.
The CX is designed to perform optimally across a wide range of velocities. This means that the bullet will expand and penetrate effectively, even at longer ranges where the impact velocity has dropped. This versatility makes the CX an excellent choice for hunters who may encounter varying shot distances or diverse hunting situations.
Ideal Hunting Applications
The CX shines in a variety of hunting applications. It’s an ideal choice for deer and antelope, delivering excellent terminal performance while ensuring reliable penetration. It’s also an effective bullet for medium-sized game, such as black bear and feral hogs, providing the stopping power needed for a clean kill. The CX is a well-rounded hunting bullet that works very well across many different species.
Comparing the Two: GMX Against CX
The most important question is: how do these two bullets compare? The most apparent difference lies in their construction. The GMX is a monolithic copper alloy bullet, while the CX features a lead core with a copper alloy jacket. This fundamental difference influences many other key characteristics. The all-copper GMX offers advantages in terms of lead-free compliance. The lead-core CX tends to be less expensive to produce.
The performance of these two bullets, while both excellent, differs subtly. The GMX is renowned for its exceptional weight retention and deep penetration, making it a top performer for larger game or situations requiring superior barrier penetration. The CX, on the other hand, often demonstrates slightly faster expansion at moderate velocities. The CX strikes a good balance between expansion, weight retention, and penetration. The CX has the advantage of its lead core, where it can expand more aggressively and is more widely available.
In terms of application, the GMX often excels in situations where deep penetration is essential, such as for large, thick-skinned game. The CX, with its controlled expansion and excellent performance, can be perfect for deer, antelope, and similar-sized animals. Both bullets are effective; it comes down to understanding their strengths.
The Good Points and Bad Points of Each
GMX
The GMX boasts an impressive list of advantages. Its weight retention, frequently over 95%, is a major strength, ensuring deep penetration and effective terminal performance. As a solid-copper bullet, the GMX is lead-free, making it an ideal option for hunters in lead-restricted areas. The design is optimized for expansion and penetration, even at a distance, and can handle thicker targets.
However, the GMX also has a few potential drawbacks. The price of the GMX can be higher than conventional lead-core bullets. Hunters might see the GMX expand a little less explosively than some bullets, particularly at lower velocities. It is a very durable bullet, but may not be the best choice if rapid, massive expansion is the primary goal.
CX
The CX also brings much to the table. The lead core enables a slightly more aggressive expansion at certain velocities, resulting in a larger wound cavity. The CX is often more affordable than all-copper bullets, making it an accessible option. Its wide availability adds to its appeal.
The CX can, however, have some disadvantages. It is not a lead-free option, which may be a concern for some hunters. While weight retention is good, it’s typically not as high as that seen with the GMX. Hunters need to also consider the environmental impact and any regulations that may apply to the use of lead-core bullets.
Picking the Right Bullet for the Hunt
The decision of which bullet to select ultimately depends on several factors: the hunting environment, the game species, the caliber and rifle, and the personal preferences of the hunter.
