The scenario that prompted this dive was a need for a reliable projectile for my .270 Winchester, capable of handling both lighter varminting and heavier game with consistent terminal ballistics. I’d grown weary of inconsistent performance from lesser-known brands, seeking a bullet that wouldn’t require extensive guesswork at the reloading bench or in the field. While other premium bullet manufacturers exist, the Partition’s unique construction has always intrigued me for its purported ability to perform across a wide velocity spectrum.
Upon receiving the box, the immediate impression was one of professional packaging. The 50 Bullet count per box is standard, but the uniformity of the bullets within was visually apparent, even before any hands-on work. The copper jackets and the distinctive Spitzer point of each round felt robust, suggesting they could withstand the rigors of being loaded into cartridges and chambered multiple times. It’s a subtle but important detail for anyone who handloads.
My initial consideration had briefly touched on monolithic copper bullets for their perceived ease of terminal performance consistency, or perhaps heavier bonded lead core bullets. However, the historical track record and unique internal design of the Nosler Partition, specifically its integral rear core support, won out for its proven versatility. My first reaction was a quiet confidence; this looked like a product that wouldn’t disappoint.
Real-World Testing: Putting Nosler 16322 Partition 270 Caliber .277 130 GR Partition Spitzer 50 Box to the Test
First Use Experience
My initial testing of these rounds focused on the reloading bench and the firing range, using my trusted custom .270 Winchester rifle. I loaded batches across the recommended powder charge spectrum for a variety of powders known to perform well with a 130 grain bullet, meticulously measuring case neck runout and overall cartridge length to ensure consistency. The Nosler bullets fed smoothly from my magazines, a crucial first step in any shooting experience.
During live-fire sessions, I observed the performance in varying conditions. The initial range trips were under clear skies and moderate temperatures, focusing on accuracy at 100, 200, and 300 yards. Later, I subjected them to the less forgiving conditions of a damp autumn day, where humidity and a light drizzle were present. The .277 diameter projectiles consistently grouped well, demonstrating that their design holds up under varied environmental factors.
Ease of use was remarkably high from the outset, particularly from a handloader’s perspective. The consistent seating depth and lack of deformation during chambering meant I could rely on predictable results. I did note one minor quirk during initial loading: the Spitzer tip, while aerodynamic, requires careful handling to avoid accidental nicks that could affect aerodynamics if not properly seated.
Extended Use & Reliability
After several months and numerous range sessions, these Nosler Partition bullets have proven their mettle. They remain a go-to for my .270 when I need assured performance, whether I’m punching paper or have bigger game in my sights. The reloaded cartridges show no signs of bullet setback or jacket deformation, even after being chambered and ejected a few times.
Durability has been exceptional; there are no visible signs of wear on the jacketed bullets themselves. Even after being seated and potentially re-seated into cases, the copper alloy jacket remains intact and the lead core is well-protected by the internal partition. This speaks volumes about the manufacturing precision at Nosler.
Maintenance is, of course, focused on the rifle and brass rather than the bullets themselves. However, their consistent performance means less time cleaning fouling caused by inconsistent burning or projectile breakdown. Compared to some monolithic bullets I’ve used, the Partition’s jacketed construction, while requiring careful loading, offers a robust solution that doesn’t require specialized cleaning techniques.
Breaking Down the Features of Nosler 16322 Partition 270 Caliber .277 130 GR Partition Spitzer 50 Box
Specifications
The Nosler 16322 Partition 270 Caliber .277 130 GR Partition Spitzer 50 Box is engineered with precision in mind. Each bullet boasts a 130 grain weight, a popular choice for the .270 Caliber that balances trajectory and terminal energy effectively. The .277 diameter ensures proper rifling engagement for optimal accuracy.
The projectile type is a Spitzer, featuring a pointed tip designed for ballistic efficiency and rapid energy transfer upon impact. Its Sectional Density of 0.242 indicates good penetration capabilities. The fully tapered copper-alloy jacket is a key component, rupturing easily at the front while the rearward section remains intact, supporting expansion.
Inside, the Partition design is crucial. It features an integral partition that separates the front and rear lead alloy core sections. This internal structure dictates controlled expansion, ensuring the front section mushrooms while the rear core, comprising more than half the original bullet weight, drives deep. Special crimp locks further enhance jacket integrity, resisting deformation even under high magnum pressures.
Performance & Functionality
The core job of this projectile is predictable and effective terminal ballistics, and it excels in this regard. When impacting at various velocities, the Partition Spitzer reliably initiates expansion. The thin jacket mouth ruptures, allowing the front core to mushroom.
Crucially, the internal partition prevents the rear core from disintegrating, ensuring deep penetration through muscle and bone. This makes it exceptionally versatile, performing reliably on targets ranging from smaller deer to larger elk, even when impact velocities are on the lower end of the optimal expansion range. The USA-made quality is evident in its consistent performance.
While the Spitzer tip is aerodynamically advantageous, its delicate nature means it’s best suited for magazine feeding in bolt-action rifles rather than extreme close-quarters applications where it might be subjected to significant abuse. Its primary strength lies in controlled expansion and deep penetration for ethical harvesting.
Design & Ergonomics
The design of the Nosler Partition is a masterclass in controlled expansion projectile engineering. The fully tapered copper-alloy jacket is meticulously formed, ensuring uniform rupture and controlled expansion. This jacket is robust enough to withstand the stresses of firing and feeding.
The Spitzer shape contributes to a good ballistic coefficient, helping the bullet maintain velocity and accuracy downrange. The lead tip, while somewhat exposed, is hardened and formed to facilitate this controlled expansion. The overall feel of the bullet, from its smooth jacket to the precise ogive, speaks of high manufacturing standards.
The integral partition is the star of the show from a design perspective. It’s this feature that truly differentiates the Partition, allowing for a controlled two-stage expansion process. This design element is what gives the bullet its reputation for deep penetration and reliable performance across a wide range of impact velocities, making it a trusted choice for serious hunters.
Durability & Maintenance
From a reloading and shooting perspective, the durability of these bullets is excellent. The copper jacket is resistant to scratching and deformation during handling and loading processes. The lead core is protected, so there’s minimal concern about core slippage or jacket separation during the loading phase.
When it comes to actual shooting, their durability translates to reliable performance downrange. They are designed to hold together under stress, ensuring that the projectile reaches its intended target intact and delivers its energy effectively. Maintenance is minimal; beyond proper rifle care, these bullets require no special attention.
The 50 Bullet quantity is standard, and while they are not designed for infinite reusability, their construction suggests a long service life for the cartridges they become part of. For a hunting bullet, the emphasis is on terminal performance rather than long-term durability in harsh physical conditions, and in that regard, they are built to perform exceptionally well.
