Uncovering the Sierra Bullets Varminter .22 Caliber 50 Grain Spitzer Blitz Rifle Bullets: Real Review
The quest for the perfect varmint round often leads down a rabbit hole of ballistic tables and anecdotal wisdom. For years, I’ve relied on a variety of projectiles for my .22-caliber centerfire rifles, each with its own strengths and limitations. It was during a particularly frustrating season of inconsistent terminal performance on prairie dogs that I decided to revisit a classic: the Sierra Bullets Varminter .22 Caliber 50 Grain Spitzer Blitz Rifle Bullets. Sierra Bullets has a long-standing reputation for quality, and these Blitz projectiles promised a balance of explosive expansion and accuracy, designed specifically for cartridges like the .222 Remington and .223 Remington. My previous experience with their MatchKing bullets had instilled a high degree of confidence in their engineering, making this particular varminter bullet a logical next step. While I briefly considered some newer monolithic designs, their cost and different performance characteristics steered me back to this well-established lead-core copper jacketed option. Upon first inspection, the bullets presented a clean, uniform appearance, with that characteristic Sierra Spitzer point, a promising sign of consistent manufacturing.
Real-World Testing: Putting Sierra Bullets Varminter .22 Caliber 50 Grain Spitzer Blitz Rifle Bullets to the Test
First Use Experience
My initial foray with these bullets took place at my favorite high-plains shooting spot, an expansive prairie dog town where precision and rapid follow-up shots are paramount. I loaded them into my trusty Remington Model 700 chambered in .223 Remington, using published load data and working up carefully. The first few shots at static targets revealed a pleasing consistency, grouping well within an acceptable margin for varmint hunting. As the targets of opportunity began to emerge, the true test began.
The conditions were typical of the high desert: moderate wind, bright sun, and temperatures fluctuating throughout the day. The Sierra Bullets Varminter .22 Caliber 50 Grain Spitzer Blitz Rifle Bullets handled these environmental factors admirably, maintaining a relatively flat trajectory that made lead correction straightforward. The intuitive nature of the Spitzer point and the consistent weight distribution meant I didn’t have to second-guess my aiming points.
Ease of use was exceptional from the get-go. There was no complex seating depth adjustment or finicky reloading process beyond standard procedures. However, one surprise was the pronounced fragmentation on impact with the smaller prairie dogs, something that, while desirable for varmint control, was more dramatic than I anticipated. This indicated the thin jacket and rapid expansion design were performing exactly as advertised.
Extended Use & Reliability
Over the course of several hunting trips and range sessions, these bullets continued to impress with their reliable performance. Weeks of being carried in ammo boxes and subjected to the vibrations of vehicle travel showed no adverse effects on bullet integrity. They maintained their shape and consistency, which is crucial for predictable accuracy.
Durability in terms of terminal ballistics remained a strong suit. Even at longer ranges, where some lighter bullets can struggle to retain energy, the Blitz bullets exhibited effective expansion and rapid incapacitation of targets. I didn’t observe any premature core separation or jacket peeling, signs of shoddy construction.
Maintenance and care for these projectiles are essentially non-existent beyond proper storage; they are designed for single use. However, cleaning my rifle after extensive use with these rounds revealed minimal copper fouling, which is a testament to the quality of the jacket material. Compared to some budget bullets I’ve experimented with, the reduced fouling and consistent performance made them a clear step up.

These specifications paint a clear picture of a purpose-built varmint bullet. The 50-grain weight is a sweet spot for many .22 caliber cartridges, offering a good balance between velocity, trajectory, and impact energy. The .22 caliber designation confirms its intended use in common varminting rounds.
The 100-round count is standard for reloading components and provides a good working quantity for a focused session. The recommended barrel twist rate is crucial; using these in faster twists (like 1:9″ or 1:7″) can indeed lead to mid-air disintegration due to excessive rotational forces, a critical warning to heed. This thin-jacketed design is optimized for velocities typical of cartridges like the .222 and .223 Remington, generally under 3600 FPS, ensuring controlled, explosive expansion rather than over-penetration or excessive fragmentation.
Performance & Functionality
The primary job of the Sierra Bullets Varminter .22 Caliber 50 Grain Spitzer Blitz Rifle Bullets is to deliver maximum terminal performance on small to medium varmints, and they excel at this. The highly explosive nature upon impact is their defining characteristic. Upon striking soft tissue, the thin copper jacket ruptures readily, causing rapid expansion and fragmentation of the lead core.
This leads to devastating wound channels and quick, humane kills on target critters. Their sleek Spitzer point contributes to a respectable ballistic coefficient, enabling a flatter trajectory and better energy retention downrange compared to round-nose or semi-wadcutter designs. The accuracy is also noteworthy; Sierra has a knack for producing match-grade consistency even in their hunting bullets, and these are no exception.
The main strength is undoubtedly their explosive expansion, ensuring virtually no over-penetration on typical varmints. A potential weakness, however, is their fragility. They are not designed for deep penetration through heavy bone or for use against larger game. Misusing them in fast-twist barrels is a critical performance failure that can result in mid-air disintegration.
Design & Ergonomics
The design of these bullets is focused on optimal ballistic performance and terminal effect. The Sierrra Spitzer point is finely formed, contributing to aerodynamic efficiency. The lightly jacketed construction is key to their frangible nature.
The overall feel of these bullets, when handling them from the box, is one of precision manufacturing. There’s a uniformity in their shape and weight that reassures the handloader. The copper jacket has a clean finish, and the lead core is seated consistently.
There are no real ergonomic considerations for the bullets themselves, as they are components. However, the design of the Spitzer point, while excellent for aerodynamics, means they require careful handling to avoid deforming the tip before firing. This is a minor point, but one that experienced handloaders are accustomed to.
Durability & Maintenance
As component bullets, the Sierra Bullets Varminter .22 Caliber 50 Grain Spitzer Blitz Rifle Bullets are designed for a single, decisive performance. Their “durability” is judged by their ability to withstand the stresses of loading and firing without deforming or fragmenting prematurely. In this regard, they are highly reliable.
They are not intended to be durable in the sense of repeated use or significant impact resistance beyond their intended application. Once fired, their structural integrity is compromised by design. Maintenance is limited to ensuring they are stored in a cool, dry place, away from excessive moisture or direct sunlight, to prevent corrosion of the copper jacket or lead exposure.
A potential failure point, as mentioned, is their incompatibility with fast-twist barrels. This isn’t a defect in the bullet itself but a critical mismatch in application that can lead to catastrophic failure in flight. Beyond that, if handled with care during the loading process, they should maintain their structural integrity until fired.
Accessories and Customization Options
As reloading components, these bullets do not come with accessories. However, they are designed to be compatible with standard reloading dies and equipment for .223 Remington and similar cartridges. The primary “customization” for these bullets comes through the handloader’s choice of powder, primer, and case.
This allows for tailoring the load to specific rifles and desired velocities, which is crucial for optimizing the performance of the Blitz bullet. For instance, selecting a slower-burning powder might achieve slightly lower velocities, enhancing their frangibility at closer ranges, while a faster powder might push them towards their optimal expansion zone at longer distances.
