Mile High Shooting Accessories carries rimfire ammunition from SK, Lapua, Hornady, CCI, RWS, and other manufacturers across .22 LR, .17 HMR, .22 WMR, and .17 HM2 calibers. The selection ranges from affordable training rounds to match-grade .22 LR sorted for tight velocity consistency, giving competitive rimfire shooters and recreational plinkers alike a source for the loads that fit their application.
Match-grade .22 LR ammo is sorted during manufacturing for tighter velocity consistency and more uniform bullet dimensions than standard production runs. That consistency translates directly to smaller groups and more predictable trajectories at the distances rimfire competitors shoot, making ammo selection one of the most impactful decisions in precision rimfire.
SK is manufactured at the same Schönebeck, Germany facility as Lapua rimfire ammunition, using the same equipment and processes. The difference is in the sorting: SK products undergo slightly less stringent lot selection than Lapua-branded rounds, which keeps pricing lower while still delivering match-capable performance. The SK lineup at Mile High Shooting includes:
Lapua sits at the top of the rimfire accuracy hierarchy. Their .22 LR lineup is tiered by how strictly each batch is tested for consistency:
Not every range session calls for match-grade ammo. Mile High Shooting carries .22 LR options from CCI, Federal, Browning, and Fiocchi for training, plinking, and general recreational shooting.
Beyond .22 LR, Mile High Shooting carries rimfire ammunition in calibers suited to varmint hunting, pest control, and specialized shooting applications.
The .17 HMR (Hornady Magnum Rimfire) is the most popular magnum rimfire cartridge for varmint and small game hunting. Its flat trajectory and high velocity make it effective on prairie dogs, ground squirrels, and other small targets at distances where .22 LR loses energy and accuracy. Mile High Shooting carries Hornady .17 HMR loads in 17-grain V-Max and 20-grain XTP configurations, both designed for rapid expansion on small-bodied game.
Fills a niche between .22 LR and .17 HMR, offering improved trajectory over .22 LR in a round that can be chambered in converted .22 LR actions. MHSA carries Hornady .17 HM2 in 17-grain V-Max for shooters who want a step up from .22 LR without moving to the magnum rimfire platform.
Delivers more energy than .22 LR for hunters who want a rimfire option with greater range and terminal performance on small game. Hornady .22 WMR 30-grain V-Max loads are designed for varmint work with the same expansion characteristics as their .17 HMR counterparts.
NRL22 and other precision rimfire match formats reward ammo consistency above all else. Start by testing several lots of SK Rifle Match or Lapua Center-X in your specific rifle; rimfire rifles are notoriously particular about which ammo they shoot well, and a lot that shoots well in one rifle may not perform the same in another. Once you find a lot your rifle likes, buy in quantity. Competitors at the national level often step up to Lapua Midas+ for the tighter velocity sorting, but many competitive shooters find that Center-X or SK Rifle Match delivers results within a few percent of the premium tiers at lower cost per round.
Hunters targeting prairie dogs, ground squirrels, and similar small game should match the caliber to the expected range. The .22 LR is effective inside 75 yards with quality ammunition. For longer shots or smaller targets, the .17 HMR extends effective range with its flatter trajectory and higher velocity. The .22 WMR is a versatile option for hunters who want more energy than .22 LR for larger small game species like rabbits and coyote-sized predators at moderate range.
Rimfire is the most cost-effective way to build and maintain marksmanship fundamentals. SK Standard Plus or CCI Standard Velocity provide the consistency precision-oriented shooters want for practice sessions, while bulk options from Federal and Browning keep costs low for high-volume plinking and new-shooter introductions. Pairing affordable rimfire ammo with a quality rimfire rifle creates a training platform that builds real skills transferable to centerfire competition.
Lapua Midas+ and Center-X are top choices for precision rimfire competition, along with SK Rifle Match and SK Long Range Match. The right load depends on your specific rifle, since rimfire barrels have strong individual preferences. The recommended approach is to test several lots in your rifle and buy in bulk once you identify one that groups well. Center-X offers a strong balance of accuracy and value, while Midas+ provides tighter velocity sorting for shooters competing at the national level.
Mile High Shooting carries .17 HMR, .22 WMR, and .17 HM2 in addition to .22 LR. The .17 HMR is the most popular magnum rimfire for varmint hunting, offering a flat trajectory and rapid expansion at distances beyond .22 LR range. The .22 WMR provides more energy for larger small game. The .17 HM2 sits between .22 LR and .17 HMR, offering improved trajectory in a cartridge compatible with converted .22 LR platforms.
For varmint hunting, Hornady .17 HMR V-Max loads offer flat trajectories and rapid expansion on small-bodied game at distances beyond .22 LR range. For close-range small game inside 75 yards, quality .22 LR like CCI Standard Velocity or SK Standard Plus is effective and affordable. The .22 WMR is a good middle ground when you want more energy than .22 LR but do not need the specialized trajectory of .17 HMR.
Rimfire cartridges have the primer compound spun into the rim of the case head, and the firing pin strikes the rim to ignite it. Centerfire cartridges use a separate primer seated in the center of the case base. This design difference means centerfire cases can handle higher pressures, which is why centerfire calibers produce more velocity and energy. It also means centerfire brass can be reloaded by replacing the spent primer, while rimfire cases cannot be reloaded because the firing pin deforms the rim. Rimfire ammunition is limited to lower-pressure cartridges like .22 LR, .17 HMR, and .22 WMR, while centerfire covers everything from pistol rounds up through magnum rifle cartridges.
