Selecting a Rimfire Scope for Precise Shooting
A rimfire rifle can be remarkably accurate, particularly with quality .22 LR ammunition and a consistent shooting position. The right optic helps you use that accuracy by making small targets clearer, wind calls easier and point-of-impact changes more predictable.
For Australian shooters, the ideal setup depends on the rifle’s purpose, the distances available at a local range and the rules that apply in your state or territory. A compact scope may suit pest control on rural property, while a higher-magnification optic is better for benchrest practice at a range near Melbourne, Brisbane or Sydney.
| Shooting purpose | Useful magnification | Reticle preference | Key priority |
|---|---|---|---|
| Hunting and field use | 2–7x or 3–9x | Simple duplex or BDC | Low weight and fast target acquisition |
| General range shooting | 3–9x or 4–12x | Fine duplex or illuminated centre dot | Versatility |
| Rimfire precision and benchrest | 4–16x or 6–24x | Fine hash-mark or target dot | Clear adjustment and parallax control |
| Short-range plinking | 1–6x or 2–7x | Uncluttered reticle | Wide field of view |
Match the Optic to the Rifle’s Role
A lightweight rimfire rifle carried around a property should not be burdened with a large tactical scope. A 3–9x optic is often a practical balance, offering a broad field of view at low power and enough magnification for precise shots at ordinary .22 LR distances. Lower power also makes it easier to find a moving or partially hidden target.
For formal target practice, weight is less important. A heavier scope with a larger objective lens, reliable turrets and adjustable parallax can make it easier to distinguish bullet holes and hold consistently. Check the rifle’s stock, action and mounting system before choosing an optic that may be physically oversized.
Australian buyers should also consider the local market. Rimfire packages and accessories can vary between metropolitan dealers and regional shops, while imported optics may have different warranty arrangements. Keep receipts and review the retailer’s delivery and dealer-transfer policies before placing an order. You can also review your customer account when managing retailer details and orders.
Select a Useful Magnification Range
Magnification should reflect the distances you actually shoot rather than the largest number printed on the box. At 50 metres, common at Australian club ranges, 9x or 12x is usually sufficient for careful .22 LR groups. At 100 metres, additional magnification can help with aiming, although mirage and ammunition limitations may become more significant than the optic’s power.
A very high-power scope can narrow the field of view, exaggerate wobble and add considerable weight. Variable-power models such as 4–16x are versatile because they allow a wide view for setup and higher power for group testing. For hunting, avoid leaving the scope permanently set at its maximum magnification if quick target acquisition matters.
Choose the Reticle and Focal Plane
A fine duplex reticle is clean and familiar, making it suitable for hunting and general shooting. Target-dot reticles can be excellent for small bullseyes, while hash-mark reticles provide reference points for holdover and windage. A busy tactical pattern may obscure a tiny target, especially in low light or against scrub.
First-focal-plane scopes keep the reticle’s proportions relative to the target as magnification changes, which is helpful when using measured holdover marks. Second-focal-plane models usually offer a finer aiming point at high power and are often less expensive. For a rimfire rifle, a second-focal-plane optic with a simple reticle may be all that is needed unless you regularly use ballistic subtensions.
Prioritise Glass, Parallax and Light
Optical clarity matters more than impressive magnification. Look for sharp detail across the image, good edge performance and controlled glare. A 40 mm objective is generally sufficient for daytime range work, while a larger objective may transmit more light but can require taller rings and a more awkward cheek position.
Adjustable parallax is especially valuable for precision shooting. Parallax error occurs when the reticle appears to shift against the target as your eye moves behind the scope. A model with a close-focus setting around typical rimfire distances, such as 25, 50 and 100 metres, is more useful than one designed only for long-range centrefire rifles.
Australia’s bright conditions, dusty ranges and hot summer days can expose weaknesses in lens coatings and mechanical construction. Sunshades help reduce glare, while capped turrets and sealed tubes are sensible for field use. At ranges near Adelaide or Perth, heat shimmer may limit practical clarity regardless of the scope’s advertised specifications.
Make Sure the Mounting System Fits
Check the rifle’s receiver rail before buying rings. Rimfire rifles may use 11 mm or 3/8-inch dovetails, Picatinny rails or proprietary bases, and these systems are not automatically interchangeable. The ring diameter must also match the scope tube, commonly one inch or 30 mm.
Use the lowest rings that clear the barrel and allow the bolt, safety and magazine to operate normally. The shooter should obtain a comfortable cheek weld without forcing the head down or stretching the neck. After mounting, level the reticle, tighten screws evenly and follow the manufacturer’s torque guidance rather than relying on feel.
Australian firearm storage and transport requirements apply to the rifle, even when the scope is treated as an accessory. State and territory rules differ, so consult your firearms registry or licensed dealer about safe storage, transport and any conditions attached to your licence. A scope purchase does not replace the approvals required for acquiring or possessing the firearm.
Test the Setup with Ammunition
Zero the rifle at a distance that suits your normal use, commonly 50 metres for .22 LR. Fire groups rather than adjusting after every individual shot, and allow the barrel to cool consistently between tests. Different loads can produce different points of impact, so confirm zero with the ammunition you intend to use.
Record elevation and windage settings, group sizes and weather conditions. At an outdoor range around Canberra or regional New South Wales, wind can shift lightweight rimfire bullets noticeably. Confirm that turret adjustments move the point of impact in the marked direction and return reliably after several changes.
When buying a used rifle and optic combination, inspect the tube for dents, check that adjustment turrets move cleanly and look for ring marks or damaged threads. A used firearm checklist can help identify issues before you commit, but arrange any Australian transfer through the licensed dealer and process required in your jurisdiction.
Choose the lightest, clearest scope that offers the magnification, reticle and parallax adjustment your shooting actually requires. Compare compatible mounts, confirm Australian legal and dealer requirements, then test the complete setup with your chosen .22 LR load before relying on it for serious target work or field use.
