Whether you’re dialing in your Ruger 10/22 at a range outside Nashville or burning through bricks of .22 LR during a weekend plinking session in the Smoky Mountains, consistent, reliable ammunition is what keeps your practice productive. Federal AutoMatch .22 LR ammunition, loaded with a 40-grain lead round nose bullet, is engineered specifically for semi-automatic rifles and pistols where cycling reliability matters most. Packed in a 325-round brick, this box gives Tennessee shooters a solid supply for extended range time without the need to reload magazines every few minutes.
What This Product Is and Who It’s For
Federal AutoMatch is a .22 Long Rifle (LR) cartridge designed with one primary goal: reliable functioning in semi-automatic firearms. Unlike bulk-pack .22 ammo that can be inconsistent in velocity or lubrication, AutoMatch uses a proprietary propellant blend and a consistent 40-grain lead round nose bullet to ensure the action cycles cleanly and repeatedly. This ammunition is intended for target shooters who want to maximize their practice sessions without dealing with failures to feed, extract, or eject. It is also well-suited for plinkers, competition shooters who need a dependable training round for rimfire matches, and any Tennessee gun owner who wants a cost-effective option for introducing new shooters to the range. While .22 LR is not typically used for home defense or large-game hunting, it remains a practical choice for small-game hunting (squirrel, rabbit) and pest control when legal and appropriate.

Feature Deep-Dive
Federal’s AutoMatch formulation starts with a carefully metered propellant charge that delivers a consistent velocity shot to shot. In rimfire ammunition, even small variations in powder weight can cause a semi-automatic firearm to short-stroke or fail to eject. Federal addresses this by using a clean-burning powder that reduces fouling buildup in the chamber and bolt face, which is a common issue with cheaper .22 ammo. The result is a round that produces enough energy to cycle the slide or bolt of most popular semi-autos, including the Ruger 10/22, Smith & Wesson M&P 15-22, and Browning Buck Mark, while keeping felt recoil low enough for rapid follow-up shots.
The 40-grain lead round nose bullet is a traditional profile that feeds reliably through both tubular and detachable box magazines. Lead round nose bullets have a shallow ogive and a smooth surface that slides easily up feed ramps, reducing the likelihood of rim-lock or nose-dive malfunctions. While some competitors use copper-plated bullets to reduce lead fouling, Federal’s lead alloy is lubricated with a dry-film wax that minimizes barrel leading when fired through standard rifled barrels. This means less time cleaning and more time shooting—a practical benefit for Tennessee shooters who visit ranges like the Stones River or Oak Ridge Sportsmen’s Association.
Another often-overlooked feature is the primer formulation. Federal uses a non-corrosive priming compound that does not leave hygroscopic salts in the bore or action. This is especially important for semi-automatic .22s, which can accumulate residue in the firing pin channel and extractor groove over hundreds of rounds. Non-corrosive primers also make it safe to store this ammunition for extended periods in a climate-controlled safe or gun cabinet, provided humidity is managed. For Tennesseans who might buy multiple bricks during a sale, knowing the ammo will perform a year later is a real advantage.
The 325-round brick packaging itself is worth noting. Unlike bulk 500- or 525-round boxes that can be awkward to handle, the AutoMatch brick is compact and stackable. Each round is held in a cardboard tray that protects the bullet tips and prevents the cartridges from rattling against each other during transport. This reduces the risk of bullet setback or powder spillage that can occur with loose-packed ammo. The brick also fits easily into a range bag or backpack without taking up excessive space, leaving room for magazines, hearing protection, and a cleaning kit.
Federal also pays attention to velocity consistency across temperature ranges. Rimfire ammunition is notoriously sensitive to temperature changes, with cold weather often causing velocity drops that affect point of impact and cycling reliability. AutoMatch is loaded to perform in a wide range of conditions, from a hot Tennessee summer range session to a cooler fall squirrel hunt. While no .22 ammo is completely immune to temperature effects, Federal’s quality control ensures that the velocity spread between rounds stays within a tighter window than many budget alternatives.
Finally, this ammunition is manufactured in the United States at Federal’s facility in Anoka, Minnesota. For Tennessee customers who prefer domestically produced products, this adds a layer of confidence in the consistency and safety of the ammunition. Federal has been producing rimfire ammunition for decades, and AutoMatch benefits from their experience with both high-volume manufacturing and precision target loads.
Ideal Use Cases
- Target Practice and Plinking: The primary use case. Reliable cycling in semi-autos means you spend more time shooting and less time clearing malfunctions. Suitable for indoor and outdoor ranges.
- Small-Game Hunting: The 40-grain lead round nose at 1,200 fps provides sufficient energy for ethical shots on squirrels, rabbits, and other small game at reasonable distances (under 50 yards). Check Tennessee Wildlife Resources Agency regulations for legal calibers and seasons.
- Competition Training: Useful for rimfire steel challenge or bullseye practice where consistent accuracy and function are more important than absolute speed.
- New Shooter Familiarization: Low recoil and low report make it a good choice for introducing new shooters to semi-automatic rifles and pistols in a controlled environment.
Compatibility Notes
Federal AutoMatch is compatible with any .22 LR firearm, including semi-automatic rifles, pistols, bolt-action rifles, lever-action rifles, and revolvers chambered for .22 LR. It is not recommended for use in .22 Short or .22 Long chambers. For semi-automatic firearms, this ammunition is optimized for barrels between 16 and 20 inches in length, but it will function in shorter barrels such as those on the Ruger Mark IV or Browning Buck Mark, though velocity will be lower. Magazines designed for .22 LR, including Ruger BX-25, Butler Creek, and factory magazines for the Smith & Wesson M&P 15-22, feed this round reliably. Holsters are not applicable to ammunition. No special accessories are required to use this product, though a good cleaning kit is recommended for rimfire firearms due to lead and carbon fouling.
