Initial impressions upon receiving the ammunition were positive; the CCI Ammunition branding is well-regarded in the shooting community, and the 40-grain lead hollow point design suggests a solid performer for its intended purpose. I considered some other standard velocity hollow points, but the explicit sub-sonic rating and advertised expansion pushed me towards this specific CCI offering. The tangible weight of the case and the clean packaging instilled a sense of confidence that this ammunition would perform as advertised.
First Use Experience
My primary testing grounds for this CCI ammunition were two distinct scenarios: a rural property for pest management and a local indoor range for accuracy assessment. The rural setting demanded quiet operation, particularly around outbuildings, where using a suppressed Ruger 10/22 is ideal. The indoor range provided a controlled environment to evaluate consistency and accuracy with a variety of .22LR firearms, including a High Standard pistol and a custom-tuned bolt-action rifle.
In the field, the low noise characteristic was immediately apparent, especially when paired with a suppressor. The rounds functioned flawlessly through the suppressed 10/22, providing effective takedowns of unsuspecting rodents. At the range, I found the CCI Sub-Sonic HP to be exceptionally reliable in my High Standard pistols, with misfires being exceptionally rare and attributable to the firearm itself rather than the ammunition. This consistency is crucial for building confidence in any firearm.
Extended Use & Reliability
Over several months and countless rounds, this sub-sonic ammunition has proven its worth. Its consistent performance in both semi-automatic and bolt-action platforms has made it a go-to choice for situations where noise reduction is paramount. I’ve fired hundreds of rounds through my various .22LR firearms, and the reliability has remained steadfast.
Durability isn’t really a factor for ammunition in the same way it is for equipment, but the integrity of the rounds themselves has been excellent. There have been no instances of damaged casings, inconsistent powder loads, or primer issues that I could discern. Maintenance for ammunition is simply proper storage, and these rounds have been kept in cool, dry conditions, maintaining their pristine state. Compared to some budget bulk options I’ve tested in the past, the CCI Sub-Sonic HP offers a noticeable improvement in consistency and performance, justifying its slightly higher price point.
Breaking Down the Features of **CCI Ammunition Sub-Sonic HP .22 Long Rifle 40 Grain Lead Hollow Point Rimfire Ammunition
56 14% Off**
Specifications
This ammunition features a 40 grain Lead Hollow Point (LHP) bullet, designed to reliably expand upon impact without fragmenting. The rounds are loaded to a sub-sonic muzzle velocity of 1050 fps, ensuring a quieter shooting experience, especially when suppressed. The cartridge case is made of brass, a standard for quality rimfire ammunition, and it utilizes consistent CCI primers. This particular offering comes in a 100-round count per box, though it’s often purchased in larger quantities, which is a common and convenient pack type for range use and small game hunting.
The 1050 fps muzzle velocity is a critical specification for sub-sonic .22LR, as it stays below the sound barrier, minimizing the sonic crack that contributes significantly to the overall noise of a shot. The 40-grain weight provides a good balance of energy transfer and trajectory for small game, while the hollow point design is intended for controlled expansion. The use of CCI primers is a significant indicator of quality, as the brand is known for their consistent ignition.
Performance & Functionality
The primary job of this ammunition is to provide a quiet, effective round for small game and target practice. In this regard, the CCI Ammunition Sub-Sonic HP .22 Long Rifle 40 Grain Lead Hollow Point Rimfire Ammunition
56 14% Off excels. The low noise output is its most defining feature, making it ideal for situations where minimizing disturbance is key. Its performance on small game has been consistently good, with reliable expansion leading to quick and humane takedowns.
Where it truly shines is in suppressed firearms, where the “crack” of the bullet breaking the sound barrier is eliminated. This makes for a significantly more pleasant and tactical shooting experience. Its accuracy has been commendable, though not match-grade, which is to be expected from a hollow-point designed for expansion. The bullet expands without fragmenting, which is a crucial detail for ethical small game hunting and for preventing excessive lead fouling in suppressed firearms.
Design & Ergonomics
Ammunition, by nature, has a very specific design dictated by its function. The 40 grain Lead Hollow Point design is classic and effective for its intended purpose. The lead composition allows for easy expansion, and the hollow point cavity is engineered to initiate this expansion reliably. The brass casing ensures good feeding and extraction in most firearms.
The ergonomics are inherently tied to the firearm being used, but the consistent dimensions and quality of these rounds contribute to smooth feeding and reliable chambering. There’s no “learning curve” with ammunition itself; its performance is dependent on the firearm’s design and condition. The markings on the CCI Ammunition are clear and informative, allowing for easy identification of caliber and type.
Durability & Maintenance
Ammunition is designed for a single use, so “durability” in the traditional sense doesn’t apply. However, the long-term stability and reliability of ammunition are crucial. Properly stored, this CCI Ammunition should remain effective for many years. The brass cases offer good corrosion resistance compared to steel, and the lead bullets are relatively stable.
Maintenance for ammunition involves proper storage to prevent moisture or extreme temperature exposure, which can degrade primers and powder. Keeping them in their original packaging or a dedicated ammunition can in a cool, dry environment is sufficient. I have experienced no issues with this ammunition that would suggest premature degradation or failure points from manufacturing defects.
Accessories and Customization Options
Ammunition itself does not come with accessories or customization options in the typical sense. However, the design of this specific round, the 40 Grain Lead Hollow Point, is itself a form of “customization” for a particular purpose. It’s engineered for controlled expansion, unlike full metal jacket (FMJ) or flat-nose variants. The sub-sonic nature is also a deliberate design choice for reduced noise.
This ammunition is compatible with any firearm chambered in .22 Long Rifle that can reliably cycle and fire hollow-point rounds. For those using suppressed firearms, the sub-sonic nature is a key “feature” that enhances the effectiveness of their setup. The availability of these rounds in 100-round boxes makes them convenient for stocking up for extended range sessions or pest control efforts.
