A Glimpse into the Past: The Birth of a Rimfire Legend
The 1970s were a time of innovation in the firearms industry. Remington, a company known for its forward-thinking approach, decided to enter the rimfire market in a more aggressive way. Their goal was to produce a high-velocity, flat-shooting rimfire cartridge that could offer superior performance compared to the then-dominant .22 Long Rifle (.22LR). The 5mm Remington Rimfire ammo was their answer.
This wasn’t just a tweak of an existing design; it was a ground-up effort. Remington designed the cartridge from scratch, aiming for a bullet that would deliver impressive downrange performance. This involved creating a dedicated rifle platform, the Remington Model 591 and 592, to house this innovative round. These rifles, built with the 5mm cartridge in mind, were a key part of Remington’s vision for this new rimfire offering.
Technical Marvels: Unpacking the Cartridge
The 5mm Remington Rimfire ammo itself was a marvel of engineering for its time. The bullet diameter, a crucial factor in its performance, measured 5mm, or roughly .20 inches. The cartridge case was designed to house a significant powder charge, contributing to the round’s high muzzle velocity. The ammunition was intended to be a potent solution for small game hunting and target shooting.
Typically, the 5mm Remington Rimfire ammo was loaded with a variety of bullet types, most commonly a hollow point design to facilitate expansion upon impact. The muzzle velocity, depending on the load, could easily reach velocities considerably faster than most .22LR rounds. This meant a flatter trajectory and increased energy at longer ranges.
While the ballistics were impressive on paper, this design pushed the limits of existing rimfire technology. Rimfire cartridges are generally more challenging to manufacture with high levels of consistency compared to centerfire rounds, and achieving uniform performance with the 5mm presented a challenge.
On the Range and in the Field: The Promise of Performance
The performance of the 5mm Remington Rimfire ammo was often lauded. In small game hunting scenarios, the high velocity and hollow point bullets translated to a fast-acting, effective round. Hunters reported success taking rabbits, squirrels, and other small animals with the cartridge.
In terms of target shooting, the flat trajectory offered advantages, especially at extended ranges. The 5mm Remington Rimfire ammo could potentially reach out further and maintain a more consistent point of impact compared to a .22LR at similar distances. However, the inherent limitations of rimfire ammunition, such as its susceptibility to wind drift, were still a factor.
The 5mm Remington Rimfire ammo offered a unique combination of speed and energy within the rimfire world. It was intended to fill a niche between .22LR and higher-powered centerfire rounds.
Challenges and the Path to Obscurity: Why Did It Fade?
Despite its promising performance, the 5mm Remington Rimfire ammo didn’t achieve the widespread popularity Remington had hoped for. Several factors contributed to its decline.
One major factor was the limited availability of the ammunition itself. Production costs likely played a role, as the specialized nature of the cartridge and the limited market demand may have made it less profitable to manufacture compared to more established rimfire rounds like .22LR.
Furthermore, the rifles chambered for the 5mm Remington Rimfire ammo, the Remington Model 591 and 592, weren’t produced in massive quantities, which naturally limited the number of potential consumers for the ammo. A self-perpetuating cycle emerged: the limited availability of the ammo discouraged wider rifle adoption, which, in turn, reduced demand for the ammunition, further limiting its availability.
The changing landscape of the firearms market also played a part. Newer cartridges emerged, like the .17 HMR, offering high velocity and improved performance, potentially overshadowing the 5mm in some applications.
The combination of these factors meant the 5mm Remington Rimfire ammo slowly faded from the scene, becoming more of a collector’s item than a mainstream choice for hunters or target shooters.
A Rare Breed: Finding the Ammunition Today
Today, finding 5mm Remington Rimfire ammo can be a challenge. The primary source of the ammunition is often through online retailers specializing in hard-to-find cartridges, and from private sellers. The costs associated with procuring this ammo are typically higher than standard rimfire options, as the rarity adds to its value.
The limited supply also means the availability of different bullet weights and styles may be restricted. Those lucky enough to own a rifle chambered for the cartridge often have to carefully manage their stock of ammo.
The Rifles: Companions to the Cartridge
The Remington Model 591 and 592, specifically designed for the 5mm Remington Rimfire ammo, remain the primary rifles associated with this cartridge. These rifles are no longer in production, making them sought-after items for collectors.
When considering purchasing a 5mm Remington rifle, the condition of the rifle is of paramount importance. The rarity of replacement parts can make repairs difficult and expensive. The wood and metal finish, the condition of the bore, and the overall functionality of the action should all be carefully assessed.
Weighing the Pros and Cons: What Are the Advantages and Drawbacks?
The allure of the 5mm Remington Rimfire ammo lies in its unique characteristics. It presents a rare combination of speed, power and a unique place in firearms history.
Advantages:
- High Velocity: The 5mm Remington Rimfire ammo offers a higher muzzle velocity compared to most standard .22LR loads, leading to a flatter trajectory and increased energy on target.
- Unique Cartridge: Owning a firearm chambered for this cartridge represents a piece of firearms history.
- Effective for Small Game: The energy and expansion of the bullet make it a viable option for small game hunting.
- Collector’s Appeal: The scarcity of the ammo and the rifles has made them highly sought-after by collectors.
Disadvantages:
- Limited Availability: Finding the 5mm Remington Rimfire ammo can be difficult, and the supply chain is far from reliable.
- High Cost: The cost per round is generally higher than other common rimfire rounds.
- Few Rifle Options: The rifles originally chambered for this cartridge are no longer in production, and those that do exist are generally collector’s items.
- Performance Limitations: While faster than .22LR, it’s still a rimfire cartridge and subject to range limitations.
Alternatives in the Realm of Rimfire
When looking for alternatives to the 5mm Remington Rimfire ammo, several options come to mind, each with their own strengths and weaknesses. The .22LR is the ubiquitous standard, offering unparalleled availability, affordability, and a wide variety of rifles and ammunition. The .17 HMR offers even higher velocities and flatter trajectories than the 5mm Remington, but ammunition and rifles tend to be more expensive.
Choosing the right rimfire cartridge depends on the specific needs of the shooter. Factors such as intended use, budget, and the availability of ammunition and rifles are key considerations.
