Use these pointers to pick the right load for your platform:
Get rimfire ammunition online or stop by the gun shop in Maricopa, Arizona to handle different brands and pick up bricks for your next range day or hunting trip. Santan Reptiles & Firearms serves customers in the nearby cities of Casa Grande and Chandler, stocking the rimfire calibers most popular for backyard plinking, jackrabbit and cottontail hunting, varmint work, and youth shooting programs across central Arizona.
Federal law sets the minimum age for purchasing rimfire ammunition at 18 for rifle calibers and 21 for handgun-classified cartridges, and Arizona follows those thresholds without adding state permits or registration. Anyone prohibited under federal law from possessing firearms is likewise prohibited from possessing ammunition, so confirm eligibility before checkout. Local discharge ordinances and Arizona Game and Fish Department regulations may apply when shooting on private property or hunting small game on open BLM land.
Transport rimfire ammunition in original packaging or sealed boxes, kept separate from loaded firearms during travel whenever practical, and store reserves in a cool, dry location to preserve primer reliability. For questions about specific brands, bulk availability, or load recommendations, contact the shop and the team will help you match stock to your firearm and shooting plans.
Rimfire cartridges have priming compound spun into the rim of the case, which the firing pin strikes to ignite the powder. Centerfire cartridges use a separate primer seated in the center of the case head, allowing for higher pressures and reloadable brass.
.22 LR produces minimal recoil, low muzzle blast, and affordable per-round costs, which lets new shooters focus on fundamentals like sight alignment, trigger control, and breathing. The cartridge also functions in a wide range of rifles and handguns suited to learners.
Standard rimfire cartridges cannot be reloaded because the priming compound is built into the rim of the case during manufacturing. Once fired, the case is considered single-use and is typically recycled rather than reloaded.
.22 LR is generally considered effective on cottontails, jackrabbits, and similar small game out to about 50 to 75 yards with high velocity loads. Beyond that distance, bullet drop and reduced energy make precise shot placement increasingly difficult.
.22 WMR (.22 Magnum) uses a longer case, higher pressures, and jacketed bullets that deliver significantly more velocity and energy than .22 LR. The two cartridges are not interchangeable, and firearms are chambered specifically for one or the other.
Rimfire chambers and bores have small dimensional variations, and bullet seating depth, lubricant, and lot consistency all affect accuracy. Many shooters test several brands and weights to find the load that produces the tightest groups in their specific rifle.
Yes, .17 HMR (.17 Hornady Magnum Rimfire) uses rimfire ignition with a necked-down .22 WMR case and a .17 caliber projectile. It delivers very high velocity and a flat trajectory, making it popular for varmint hunting at extended rimfire ranges.
Store rimfire cartridges in their original packaging or sealed containers in a cool, dry location with stable temperatures and low humidity. Properly stored modern rimfire ammunition can remain reliable for many years, with climate control especially important through Arizona’s intense summer heat.
