A Journey into Cartridge Customization
The Essence of Wildcatting
The world of firearms is vast, a landscape dotted with standardized cartridges, each meticulously engineered for specific tasks. Yet, beyond the well-trodden paths lie the wildcat cartridges, the products of adventurous minds and dedicated hands. These cartridges, born from the passion for pushing boundaries and seeking the ultimate in performance, often represent a unique blend of ballistics and purpose. Today, we delve into one such fascinating creation: the .270/.35, a cartridge that combines the legacy of one design with the raw power of another.
The Genesis of the .270/.35
Before we explore the .270/.35, it’s worth appreciating the artistry inherent in wildcatting. The process involves taking an existing cartridge case—a “parent case”—and modifying it. This might involve changing the neck diameter to accept a different bullet, adjusting the shoulder angle, or altering the overall length. The goal is often to optimize performance for a specific purpose, whether it’s to enhance accuracy, increase power, or tailor a cartridge for a specific hunting application. Wildcatting is about taking ownership of the performance and achieving what standardized cartridges can’t always deliver.
The .270/.35’s story begins with the venerable .270 Winchester, a cartridge that, in itself, is a testament to innovative design. The .270 Winchester, introduced in the early nineteen-twenties, quickly gained fame for its flat trajectory and exceptional long-range performance. It’s been a favorite among hunters who seek a balance of effectiveness across different terrains. The .270 Winchester’s slender bullets offered advantages in terms of range, wind resistance, and target impact.
The .270 Winchester provided the perfect foundation for the .270/.35. By altering the case, the cartridge was then transformed to receive a larger-diameter .35-caliber bullet. .35 caliber bullets are generally associated with enhanced knock-down power, suitable for hunting bigger game. The exact details of the .270/.35’s creation may be obscure, lost to the annals of wildcat cartridge history. Nonetheless, it can be deduced that a firearms enthusiast, an individual seeking to merge the .270 Winchester’s case with a larger bullet diameter, brought this project to life.
Delving into Ballistic Performance
Bullet Characteristics
The .270/.35 is defined by its ballistic potential. The heart of its performance lies in the .35 caliber bullet, typically ranging in weight from one hundred and eighty grains up to nearly two hundred and fifty grains. This allows for a range of bullet choices, each with its own characteristics.
Velocity and Energy
Regarding velocity, the .270/.35 aims to deliver significant muzzle velocity. With the right powders and handloads, the .270/.35 can achieve muzzle velocities. The precise velocity is variable, determined by factors, such as the barrel length and the selected powder.
Trajectory of the Round
The .270/.35’s trajectory is another important aspect. Because it fires a .35 caliber bullet with more weight, it does experience more bullet drop over longer distances. Nonetheless, it still provides adequate accuracy for hunting at reasonable ranges.
Accuracy Potential
The accuracy of the .270/.35 is dependent on various factors, including the quality of the components, the handloading skill of the shooter, and the quality of the rifle. When properly built and handloaded, a .270/.35 rifle can demonstrate great accuracy potential, and it’s not uncommon to achieve groups within an inch or even less at one hundred yards.
Weighing the Advantages and Disadvantages
Advantages
Every cartridge has its pros and cons, and the .270/.35 is no exception.
Increased Knock-Down Power: The most significant advantage is the potential for improved stopping power. The heavier .35-caliber bullets deliver considerable energy, which makes them exceptionally suited for hunting big game. This also provides the hunter an additional advantage in certain situations.
Trajectory at a Lower Range: the .270/.35’s trajectory is flatter when compared with the trajectory of other .35 caliber cartridges. This adds to a smoother shot.
Versatility: While specialized, the .270/.35 offers the potential for versatility, depending on the bullet selection and handloading. It can be tailored for various applications, from deer-sized animals to larger game.
Disadvantages
Limited Availability: One of the biggest drawbacks is the limited availability of both ammunition and rifles chambered in this round. .270/.35 is a custom cartridge and has to be hand-loaded.
Custom Handloading Required: Reloading is required for the cartridge. Reloading offers a wider range of bullet options and allows for performance customization, but it does require a significant investment.
Rifle Customization Needs: You will need a custom-built rifle or a rifle that has been re-chambered to accept the .270/.35 cartridge. This means you’ll need to seek the services of a gunsmith.
The Art and Science of Handloading .270/.35
Sourcing Brass
Reloading the .270/.35 is essential, as there’s no factory-loaded ammunition readily available.
Brass casings are not available from the factories, so reloading will involve making cases from another cartridge, such as the .270 Winchester. Using proper reloading practices is essential for safety and performance.
The Role of Dies
Reloading dies are necessary to make and reload .270/.35 cartridges. You will need dies made specifically for this wildcat cartridge.
Selecting Propellants and Primers
Powder selection plays a critical role in maximizing the performance of the .270/.35. The ideal powder will be something that is a good fit for the bullet weight you’re intending to use. Many handloaders have achieved successful results with powders that are suitable for other cartridges, too. Primers should be chosen carefully.
Making the Right Bullet Selection
Bullet selection is critical for the .270/.35. There are a wide array of options, with each bullet type being designed for a specific purpose. For hunting purposes, consider bullets designed to provide deep penetration and controlled expansion, such as those with bonded cores or robust jacket designs.
Putting Safety First
Handloading can be enjoyable, but it requires an unwavering commitment to safety. Always follow the manufacturer’s instructions for loading and handling firearms.
Exploring Potential Applications
Hunting Applications
The .270/.35’s potential extends into several areas.
The .270/.35’s capabilities provide a real benefit to the hunter. With heavier bullets, the cartridge becomes suitable for a variety of animals, including deer, wild hogs, and other medium-to-large game. The combination of power and range makes it an excellent choice for hunting in various environments.
Rifles and Barrel Considerations
Platform Selection
The .270/.35 is a cartridge that needs a proper rifle to maximize its potential.
For building a rifle, a strong bolt-action rifle would be a great starting point. These rifles typically have a reputation for ruggedness, providing a solid platform for the .270/.35.
Barrel Twist Rates
The barrel twist rate is an important specification when it comes to the accuracy and stability of the .270/.35. A twist rate is typically one in twelve inches. The proper twist rate is determined by the weight and design of the bullet that you intend to use.
Custom Builds
You can custom build a rifle to accommodate a .270/.35 cartridge. Working with a skilled gunsmith to achieve the optimal results is a wise investment.
Examining Alternatives and Comparisons
It’s useful to compare the .270/.35 with other cartridges to determine its place in the shooting world.
Comparison with Other Cartridges
.35 Whelen: It is an excellent choice, but it is limited by the .30-06 case.
.358 Winchester: A high-performance option, which is often chambered in compact rifles.
Conclusion: A Niche Cartridge with a Unique Appeal
The .270/.35 is more than just another wildcat cartridge. It is a testament to the passion of shooting enthusiasts. The .270/.35 has the potential to be an effective cartridge in the hands of a knowledgeable shooter who is willing to put in the time and effort.
