A Look at the .17 HMR (Hornady Magnum Rimfire)
History and Development
The .17 HMR, short for Hornady Magnum Rimfire, is a rimfire cartridge that burst onto the scene, offering a level of performance that shook up the varmint and small game hunting landscape. Its introduction brought a new level of precision and speed to rimfire options. It was born from a collaboration between Hornady and Marlin. Its development focused on creating a higher-velocity .17 caliber cartridge based on the .22 WMR case.
Cartridge Design
This innovative design significantly enhanced the performance of rimfire rifles. The .17 HMR’s appeal stems from its flat trajectory, making it incredibly accurate at reasonable distances, and its ability to deliver impressive energy for its size.
This cartridge uses a small, lightweight bullet, typically weighing between 17 and 20 grains. These bullets are designed to travel at incredible speeds, well exceeding the velocities of many .22 Long Rifle loads. The velocity and bullet weight combination is a critical factor in its ballistic capabilities.
Because the .17 HMR is a rimfire cartridge, it’s relatively simple in design. The firing pin strikes the rim of the case to ignite the priming compound. This system contributes to the affordability of both rifles and ammunition.
Ballistics
The .17 HMR’s ballistic profile is a key selling point. Its relatively flat trajectory translates to less bullet drop at longer ranges compared to many other rimfire options. This makes it easier to hit targets accurately at a distance, requiring less holdover (the amount the shooter needs to aim above the target to compensate for bullet drop).
Common Uses and Applications
This cartridge has found its niche in various applications. Varmint hunters, in particular, have embraced the .17 HMR for its effectiveness on prairie dogs, groundhogs, and other small, destructive pests. Its accuracy and manageable recoil make it a great choice for taking down these targets.
Additionally, the .17 HMR is a popular choice for small game hunting. Those who hunt squirrels, rabbits, and other similar animals often find the .17 HMR to be a viable option. Its relatively low noise level, compared to some centerfire cartridges, is also an advantage in populated areas.
On the target shooting front, the .17 HMR is an excellent choice for plinking and informal target practice. The affordability of ammunition and the accuracy of the cartridge make it an enjoyable and cost-effective way to hone your shooting skills.
Pros of .17 HMR
The advantages of the .17 HMR are numerous. Beyond accuracy, the .17 HMR enjoys the benefit of affordable ammunition, which is a huge plus for shooters looking to practice regularly. Its low recoil makes it comfortable to shoot for extended periods, and the various rifles chambered in this cartridge are often lightweight and easy to handle.
Cons of .17 HMR
However, the .17 HMR isn’t perfect. Its effective range, when compared to centerfire cartridges, is limited. While it is accurate out to a couple of hundred yards, the wind can significantly impact its trajectory, due to the lightweight bullets. This means that shooters need to be mindful of wind conditions and compensate accordingly. Also, while energy on target is reasonable, it can be less effective on larger varmints at longer distances.
A Deep Dive into the .17 Hornet
History and Development
The .17 Hornet is a centerfire cartridge, offering a different set of capabilities compared to its rimfire counterpart. It’s a scaled-down version of the .22 Hornet, necked down to accept a .17 caliber bullet. The .17 Hornet’s heritage gives it a unique place in cartridge history.
Cartridge Design
The .17 Hornet is a centerfire cartridge, relying on a primer seated in the center of the case to initiate the firing process. The design choice gives the cartridge greater flexibility in terms of bullet selection and reloading options, as well as the ability to house more powder.
Ballistics
In terms of ballistics, the .17 Hornet offers a significant advantage over the .17 HMR, particularly in terms of velocity. The bullets, also typically weighing between 20 and 25 grains, leave the muzzle at a much higher speed than those fired by the .17 HMR.
The increased velocity translates to a flatter trajectory and a longer effective range. The .17 Hornet can accurately reach targets at further distances, making it a solid choice for varmint hunting in open areas.
Furthermore, the .17 Hornet delivers more energy downrange compared to the .17 HMR. This increased energy translates to a more decisive impact on target, giving it an edge on larger or tougher varmints.
Common Uses and Applications
The .17 Hornet has found its home in varmint hunting, where its longer effective range and higher energy make it well-suited for taking on a wider range of targets, including coyotes, woodchucks, and other similar species.
While the .17 Hornet is a capable cartridge for small game, the increased power allows for hunters to take on targets where the .17 HMR may struggle.
Pros of .17 Hornet
The advantages of the .17 Hornet include its extended range, giving hunters and target shooters more versatility. The .17 Hornet handles wind drift significantly better than the .17 HMR, providing more reliable accuracy in challenging conditions.
The greater power offers more stopping power, which can be crucial when hunting larger varmints or when clean kills are essential. The .17 Hornet is more efficient at longer ranges, leading to greater success in the field.
Cons of .17 Hornet
However, it’s also important to acknowledge the disadvantages of the .17 Hornet. Ammunition for this cartridge is generally more expensive, which can impact the overall cost of shooting. Recoil is noticeably higher than that of the .17 HMR, although still quite manageable. Moreover, due to its centerfire design, the .17 Hornet may require more effort to clean and maintain a centerfire rifle.
A Comparative Analysis
Comparing the .17 Hornet and .17 HMR reveals some important distinctions. In the realm of accuracy, both cartridges are capable of exceptional accuracy. The .17 HMR, due to its flat trajectory and consistent bullet weight, often edges out the .17 Hornet in pure accuracy at shorter ranges. However, at longer distances, the .17 Hornet’s flatter trajectory and superior resistance to wind drift come into play.
When we consider range, the .17 Hornet clearly surpasses the .17 HMR. The .17 Hornet is effective out to approximately 300 yards and beyond, while the .17 HMR begins to show signs of drop and wind influence at around 200 yards.
In terms of energy, the .17 Hornet delivers significantly more downrange energy than the .17 HMR. This translates to a more decisive impact and a greater ability to drop targets at further distances.
The .17 Hornet has a considerably higher cost for both ammunition and rifle. The increased cost is a factor that must be considered when deciding. The .17 HMR is usually a more budget-friendly option.
