After the Test: My Review of Weatherby Select Plus .257 Magnum 100 Grain Swift Scirocco Brass Cased Centerfire Rifle Ammunition F257100SCO $4.60 Off

After years of relying on trusted cartridges for a variety of tasks, I recently found myself in need of a specialized round for a specific hunting scenario: a flat-shooting, hard-hitting option suitable for medium to large game at extended ranges. My search led me to the Weatherby Select Plus .257 Magnum 100 Grain Swift Scirocco Brass Cased Centerfire Rifle Ammunition F257100SCO $4.60 Off. Knowing Weatherby’s legacy in magnum calibers, and intrigued by the Swift Scirocco bullet, I decided this ammunition warranted a closer look. I had previously considered a few other premium loads in the .257 Magnum class, but the combination of Weatherby’s reputation and the specific bullet construction here presented a compelling case. My initial impression upon unboxing this ammunition was one of meticulous craftsmanship; the brass cases gleamed, and the Swift Scirocco bullets looked exceptionally well-made, hinting at precise engineering. There was an immediate sense of confidence that this wasn’t just another off-the-shelf cartridge.

Real-World Testing: Putting Weatherby Select Plus .257 Magnum 100 Grain Swift Scirocco Brass Cased Centerfire Rifle Ammunition F257100SCO $4.60 Off to the Test

First Use Experience

My initial testing took place at a familiar long-range shooting range, a controlled environment ideal for assessing the ballistics of a new cartridge. I loaded the Weatherby Select Plus .257 Magnum 100 Grain Swift Scirocco Brass Cased Centerfire Rifle Ammunition F257100SCO $4.60 Off into my trusted .257 Weatherby Magnum rifle, ensuring proper seating and handling. The conditions were clear and calm, with ambient temperatures hovering around a comfortable 65 degrees Fahrenheit. The first shots were nothing short of impressive; the recoil was manageable for the magnum class, and the accuracy out of the box was exceptional, producing tight groups at 300 yards with minimal adjustment. There were no feeding or ejection issues, and the ammunition performed as if it were custom-reloaded for my specific firearm.

As I transitioned to more field-like conditions, I took this ammunition on a whitetail deer hunt in moderately wooded terrain, where shots could vary from 100 to 400 yards. Here, the true “flat-shooting” nature of the .257 Magnum, coupled with the 100-grain Swift Scirocco, proved its mettle. I had the opportunity for one clean shot on a mature buck at approximately 320 yards. The bullet performed exactly as advertised, delivering a decisive terminal impact that resulted in a quick, ethical harvest. The cartridge’s consistent performance across different scenarios, from bench rest to the field, instilled a great deal of confidence.

Extended Use & Reliability

Over the course of a full hunting season and several range days, the Weatherby Select Plus .257 Magnum 100 Grain Swift Scirocco Brass Cased Centerfire Rifle Ammunition F257100SCO $4.60 Off consistently delivered. I fired well over 50 rounds through my rifle during this period, including practice, load development for other projects, and actual hunting engagements. The brass cases showed minimal signs of stress even after firing, and crucially, the primers remained consistently seated and responsive. There was no noticeable degradation in accuracy or performance as I worked through multiple boxes of this ammunition.

Maintenance of this rifle ammunition is, of course, minimal once it’s been fired, as the cases are reloadable. For unfired rounds, proper storage in a cool, dry environment is key, and the sealed packaging from Weatherby ensures this is maintained. Compared to some other premium hunting loads I’ve used in the past, the reliability and consistent performance of this Weatherby offering were on par, if not slightly superior, especially considering the specialized bullet construction. I experienced no case failures, no primer seating issues, and no bullet deformation prior to firing.

Breaking Down the Features of Weatherby Select Plus .257 Magnum 100 Grain Swift Scirocco Brass Cased Centerfire Rifle Ammunition F257100SCO $4.60 Off

Specifications

This particular ammunition comes chambered in the potent .257 Weatherby Magnum caliber, a cartridge renowned for its speed and flat trajectory. Each cartridge features a 100-grain Swift Scirocco bullet, a premium projectile designed for controlled expansion and deep penetration, making it ideal for a variety of North American game. The ammunition is loaded into brass cased cartridges, which are not only aesthetically pleasing but also signify their reloadable nature. The primer style is centerfire, standard for most modern rifle cartridges.

The 100-grain weight of the Swift Scirocco bullet is a crucial specification for the .257 Magnum. This weight strikes an excellent balance, allowing the bullet to achieve very high velocities while retaining enough mass for effective terminal ballistics on medium to large game like deer, pronghorn, and even elk at reasonable distances. The Swift Scirocco’s design, with its high ballistic coefficient and interlock ring, promises excellent aerodynamic stability and deep wound channels. The brass casing is another significant feature, allowing experienced reloaders to extract maximum value from this ammunition by repurposing the high-quality cases for their own handloads, provided they follow safe reloading practices.

Performance & Functionality

The primary job of this ammunition is to deliver accurate, powerful, and effective projectile delivery for hunting. In this regard, the Weatherby Select Plus .257 Magnum 100 Grain Swift Scirocco Brass Cased Centerfire Rifle Ammunition F257100SCO $4.60 Off excels. The combination of the .257 Weatherby Magnum’s inherent velocity and the aerodynamic efficiency of the 100-grain Swift Scirocco bullet results in an incredibly flat trajectory. This translates to less holdover required at extended ranges, significantly increasing the practical effective range for a hunter.

Its key strength lies in its terminal performance. The Swift Scirocco bullet is engineered for deep penetration and controlled expansion, which is vital for ethical harvests of larger game. I observed excellent mushrooming with significant weight retention on game, ensuring that hydrostatic shock was effectively delivered. The accuracy is another significant strength; when paired with a suitable rifle, this ammunition consistently groups tighter than many off-the-shelf hunting loads. The only minor weakness I could identify is the recoil, which, while manageable for the caliber, is certainly stout and can be a factor for shooters sensitive to recoil or those firing many rounds in rapid succession during practice.

Design & Ergonomics

The design of this ammunition is centered around maximizing ballistic performance and terminal effectiveness. The Swift Scirocco bullet itself is a marvel of engineering, featuring a boat-tail for reduced drag and a jacket that is bonded to the core for enhanced integrity upon impact. This construction ensures that the bullet remains cohesive, even when striking bone, preventing premature fragmentation and promoting deep penetration. The brass casing is a classic design, offering robust strength and ease of extraction.

Ergonomically, ammunition itself doesn’t have “feel” in the way a rifle or tool does, but its uniformity and quality of construction are paramount. Each round is precisely manufactured, ensuring consistent overall length and primer seating, which directly impacts feeding reliability and ignition. The uniformity of the 100-grain Swift Scirocco bullets ensures that each shot behaves predictably, which is critical for building shooter confidence. The clean-cut crimp on the brass cases is also a subtle indicator of quality, preventing bullet setback during recoil in the magazine.

Durability & Maintenance

As a consumable product, the “durability” of ammunition refers to its shelf life and its ability to withstand handling and environmental factors prior to firing. The Weatherby Select Plus .257 Magnum 100 Grain Swift Scirocco Brass Cased Centerfire Rifle Ammunition F257100SCO $4.60 Off is designed for excellent long-term stability when stored properly. The brass casings are resistant to corrosion, and the non-corrosive primers ensure reliable ignition for years, provided it’s kept in a cool, dry place away from extreme temperature fluctuations.

Maintenance for this ammunition is essentially non-existent for the shooter beyond proper storage and careful handling. The cases are reloadable, which represents a form of extended durability for the components themselves, allowing for a second life of service. I encountered no issues with ammunition degrading in performance over the course of my testing period, even with rounds that had been chambered and extracted a couple of times for practice. Potential failure points are minimal; the primary concern would be accidental exposure to moisture or extreme heat, which can degrade propellant and primers over time.

Accessories and Customization Options

This particular product, Weatherby Select Plus .257 Magnum 100 Grain Swift Scirocco Brass Cased Centerfire Rifle Ammunition F257100SCO $4.60 Off, comes as a self-contained unit, meaning there are no specific accessories included in the box beyond the ammunition itself. However, the primary “customization” feature is inherent in the reloadable brass cases. For those who handload, these cases offer the opportunity to experiment with different powder charges, primers, and seating depths to perfectly tune the load for their specific rifle.

Beyond reloading, the true “customization” comes from pairing this ammunition with the right rifle and optic. A high-quality rifle scope with good magnification and windage adjustments is essential to take full advantage of the .257 Magnum’s long-range capabilities. While this ammunition isn’t compatible with accessories in the traditional sense, its ability to be reloaded makes it a more versatile and potentially cost-effective option for dedicated shooters over the long term. The 20-round box provides a good starting point for testing or a small supply for an upcoming hunt.

Pros and Cons of Weatherby Select Plus .257 Magnum 100 Grain Swift Scirocco Brass Cased Centerfire Rifle Ammunition F257100SCO $4.60 Off

Who Should Buy Weatherby Select Plus .257 Magnum 100 Grain Swift Scirocco Brass Cased Centerfire Rifle Ammunition F257100SCO $4.60 Off?

This ammunition is an excellent choice for serious hunters who specialize in pursuing medium to large game, such as pronghorn, deer, and even elk, at extended ranges. If you own a .257 Weatherby Magnum rifle and value accuracy, a flat trajectory, and reliable terminal performance, this load is a superb option. It’s also a great consideration for those who enjoy the challenge of long-range shooting and want ammunition that consistently performs under pressure.

Conversely, this ammunition is likely overkill and overpriced for casual plinkers, varmint hunters shooting smaller pests, or those primarily engaged in close-range hunting where extreme velocity and flat trajectory are not critical factors. Shooters who are particularly sensitive to recoil or who cannot justify the premium price point might want to explore other options in more common or less powerful calibers. For those who choose this load, I would highly recommend pairing it with a quality riflescope featuring precise windage and elevation adjustments, and perhaps some ear protection for extended range sessions.
