A rimfire rifle can make a great afternoon at the range feel frustrating when the ammunition does not cycle consistently, print predictably, or suit the job at hand. The best rimfire ammo brands earn their reputation by producing dependable loads across common calibers, especially .22 LR, .22 WMR, and .17 HMR. Still, the right box is not always the most expensive one. Your firearm, shooting distance, intended use, and budget all matter.
What separates the best rimfire ammo brands
Rimfire ammunition is available in a wider range of load types than many new shooters expect. A bulk pack intended for informal plinking is built around a different priority than match-grade .22 LR made for small groups at 50 yards. Hunting loads may use plated hollow points for terminal performance, while suppressed shooting often calls for a subsonic load that stays below the speed of sound.
Consistency is the main dividing line. Good rimfire ammunition should chamber cleanly, fire reliably, and deliver repeatable velocity and point of impact. Because rimfire cartridges use priming compound spun into the cartridge rim, even premium ammunition can occasionally show lot-to-lot differences. That is why testing a few options in your own firearm is more valuable than relying only on a brand name.
For semi-automatic firearms, cycling is another practical factor. A low-velocity or subsonic .22 LR load may be accurate and quiet, but it may not reliably operate every semi-automatic action. Conversely, a high-velocity load can run well in a pistol or rifle but produce more noise and a different point of impact. Select ammunition around the firearm and purpose, then confirm performance during a safe range session.
CCI: a dependable choice for broad use
CCI is one of the most recognized names in rimfire ammunition because its lineup covers everyday range use, hunting, specialized applications, and .22 WMR and .17 HMR options. For many shooters, CCI Standard Velocity is a sensible starting point for general .22 LR practice. It is commonly chosen for its balance of manageable velocity, clean shooting characteristics, and practical accuracy.
CCI Mini-Mag remains a popular high-velocity .22 LR option for semi-automatic pistols and rifles. It is often selected when dependable cycling is a priority. For small-game hunting, CCI offers hollow-point and segmented projectile designs intended for appropriate field use. As with any hunting ammunition, confirm local regulations, choose a load appropriate for the game, and practice for precise shot placement.
CCI also serves shooters looking for specialty ammunition. Quiet-focused loads, shotshell-style rimfire cartridges, and suppressor-oriented options all have specific uses, but they are not universal solutions. A quiet load may not cycle a semi-automatic firearm, and a shotshell cartridge has very limited effective range. Read the box carefully and match the load to the task.
Federal: strong value from range packs to match loads
Federal offers practical rimfire ammunition for high-volume training as well as more accuracy-focused shooting. Its bulk and value-pack .22 LR options are widely used for recreational range sessions, youth training under qualified adult supervision, and informal steel or paper-target practice. For shooters who go through several hundred rounds in a session, cost per round is a legitimate consideration.
Federal AutoMatch is commonly considered by semi-automatic .22 LR owners who want a load designed with autoloading firearms in mind. It can be a useful test option for pistols and rifles that are sensitive to lower-powered ammunition. Federal also produces hunting-oriented loads and match-grade choices, giving shooters room to move from casual practice into more precise work without changing brands.
The trade-off with bulk ammunition is that it is generally made for volume and utility rather than single-lot precision. It can still shoot very well in a particular firearm. If your goal is close groups or competition, buy a few smaller boxes of higher-grade ammunition and compare them against your regular range load before stocking up.
Winchester and Remington: familiar brands for practical shooting
Winchester rimfire ammunition is a familiar option for shooters looking for accessible .22 LR, .22 WMR, and .17 HMR loads. Its offerings commonly include bulk-pack .22 LR for range use and hollow-point choices for small-game hunting. Winchester Super-X has a long-standing place in the rimfire market, particularly among shooters who prefer conventional high-velocity loads.
Remington also remains a recognized rimfire name, with .22 LR ammunition that can fit high-volume range use and field applications. Availability can vary by product line and local inventory, so it makes sense to evaluate current offerings based on the exact load rather than buying solely on past experience with the brand.
With both brands, inspect cartridges as you load magazines or cylinders. Look for damaged bullets, deeply dented cases, or excessive wax buildup. This is good ammunition-handling practice regardless of manufacturer, especially when using bulk-packed rimfire rounds.
Aguila: versatile rimfire options worth testing
Aguila has built a solid following among .22 LR shooters by offering standard-velocity, high-velocity, subsonic, and specialty loads at a range of price points. Aguila Standard Velocity is often considered by shooters who want a general-purpose training load, while its high-velocity options can be useful for firearms that run best with more energetic ammunition.
The brand is also known for unusually heavy-bullet and specialty .22 LR products. These can be interesting for specific setups, but they are not automatically better for every rifle or pistol. Heavy-bullet loads may have a noticeably different trajectory and may not stabilize or cycle the same way as conventional 36- or 40-grain ammunition. Test before relying on any specialty load for a serious purpose.
Eley, Lapua, and SK: for precision rimfire work
When group size matters more than cost per round, Eley, Lapua, and SK belong in the conversation. These brands are strongly associated with target shooting, rimfire competition, and rifles capable of extracting the benefit of carefully made ammunition. Their match and premium lines are typically priced above bulk .22 LR, but the tighter production controls and more consistent velocity can make a visible difference in the right rifle.
Precision rimfire shooters should think in terms of lots, not just labels. One lot of a respected match load may produce exceptional results in a particular rifle, while another may be merely good. Serious competitors often test multiple lots at their typical shooting distances and record group size, velocity, and point of impact. That process is more useful than assuming the highest-priced box will automatically be the best performer.
These loads are not limited to competition shooters. If you own a quality bolt-action rimfire and want to see what it can do from a supported position, a box of match ammunition is a worthwhile benchmark. Just keep expectations realistic: fundamentals, optics mounting, wind reading, and a stable rest remain part of the result.
Choose rimfire ammunition by application
For casual range use, reliable bulk-pack or standard-velocity .22 LR from CCI, Federal, Winchester, Remington, or Aguila can be a practical fit. Buy a manageable quantity first and see how it performs in your firearm. A load that feeds well and groups consistently is more useful than a bargain that causes repeated malfunctions.
For semi-automatic pistols and rifles, prioritize reliable cycling. High-velocity loads frequently provide the energy needed for dependable function, though every firearm is different. Keep the firearm clean, use magazines in good condition, and follow the manufacturer’s ammunition recommendations.
For hunting, choose a load made for the game and conditions you expect. Hollow points are common choices for appropriate small-game applications, while .22 WMR and .17 HMR may offer flatter trajectories and more energy at longer rimfire distances. Know the limits of your equipment, observe all state and local hunting rules, and avoid shots beyond your practiced capability.
For target shooting and precision practice, standard-velocity and match-grade .22 LR deserve attention. They may reduce the disruptive effects associated with transonic flight at common rimfire distances, and they often produce more consistent groups in accuracy-oriented rifles. The only way to know is to test.
Buy smart and store rimfire ammunition correctly
Before purchasing in quantity, try several loads through your firearm. Record the brand, product name, bullet weight, velocity rating, distance, group size, and any malfunctions. Even a simple notebook can prevent expensive guesswork later. Once you identify a load that performs well, purchasing the same lot when available can help maintain consistency.
Store ammunition in a cool, dry location away from heat, moisture, and unauthorized access. Keep cartridges in their original packaging when possible so the caliber and lot information remain clear. Responsible ownership also means confirming applicable federal, state, and local requirements before purchasing, transporting, or using ammunition.
The best choice is the load that runs safely and reliably in your firearm, fits the job, and gives you confidence every time you head to the range or field. Start with a few proven brands, test with purpose, and let your own results determine what belongs in your range bag.
