15 Best 22 Wmr Scope of 2026 For Varmints Past 100 Yards
Mounting a standard rimfire optic designed for slow .22 LR cartridges is the fastest way to waste expensive ammunition and botch clean shots. Most basic rimfire scopes come locked with a 50-yard fixed parallax and holdover reticles tuned for steep, looping drop curves. Push that setup past 75 or 100 yards, and the reticle drifts across tiny pests while the target picture softens into a frustrating blur. Mismatched mounting hardware only compounds the headache when included dovetail clamps fail to lock onto a modern receiver rail.
Wringing the real potential from a magnum rimfire requires an optic built for speed and distance. Small game hunting demands an adjustable objective to eliminate target float across shifting yardages, alongside multi-coated glass that gathers critical light during dawn and dusk feeding hours. Double-checking receiver dimensions between an 11mm dovetail and a 20mm Picatinny rail secures a rock-solid zero that stays true. The options below deliver the precise tracking, sharp focus, and dependable mounting needed to drop pests cleanly well past the century mark.

Can I use a standard .22 LR rimfire scope on a .22 WMR rifle?
You can mount one, but the holdover points will not match the flight of your bullet. Standard rimfire reticles and elevation drums, including multi-grain turrets designed for .22 LR rounds, are calibrated for lower muzzle velocities and steeper drop rates. Mounting one on a faster .22 WMR rifle leads to aiming errors beyond 75 yards. Choosing an optic with a clean 30/30 crosshair or one calibrated specifically for .22 WMR trajectories gives you predictable elevation marks. If you shoot at changing target distances, investing in an optic designed for accurate holdovers keeps your point of impact consistent across variable ranges.
Do I need an adjustable objective for shooting varmints at 100 yards?
Yes, an adjustable objective or side parallax adjustment is essential when tracking small targets at 100 yards. Scopes with a fixed objective are often factory set for closer ranges, which creates parallax error and a blurry sight picture when viewing targets further out. Models equipped with an adjustable objective, such as the Hawke Vantage IR 4-12x40 AO or the BSA Sweet 22 AO, allow you to dial out optical drift and bring small game into sharp focus. Correcting parallax ensures your crosshair stays pinned to your point of aim regardless of minor head movements behind the eyebell.
Will the included scope rings fit my rifle receiver grooves?
It depends on whether your rifle uses grooved receiver slots or a raised rail. Many rimfire optics come packaged with 3/8-inch tip-off dovetail rings designed for classic grooved receivers, like those on a Marlin Model 60 or Remington 597. Other optics, such as the CVLIFE 3-9x40AO, include 20mm mounts built for Picatinny or Weaver bases. Inspect your rifle receiver before buying to confirm whether you need 3/8-inch dovetail rings or a 20mm rail accessory like the TANDEMKROSS PMR-30 mount to achieve a secure fit.
What magnification range is best for hunting with a .22 WMR?
A variable magnification range of 3-9x or 4-12x provides the most practical versatility for .22 WMR varmint hunting. Fixed 4x magnification, common in 4x32 and 4x20 plinking optics, works well for close shots inside 50 yards but lacks the target detail needed for small pests at 100 yards and beyond. Moving to a 3-9x or 4-12x optic allows you to keep a broad view when searching field edges on low power, then dial up magnification to clearly identify small game before pulling the trigger.
Does a 40mm objective lens offer an advantage over a 32mm lens?
Yes, a 40mm objective lens lets in noticeably more ambient light than a 32mm or 20mm objective. This higher light gathering helps you spot varmints during early morning and late evening when pests are most active. Keep in mind that a larger 40mm objective bell sits closer to the rifle receiver and barrel. You should always confirm that your chosen ring height provides proper barrel clearance so the optic housing does not touch the barrel or interfere with iron sights.
How can I verify that a .22 WMR scope will hold up in damp weather?
Check the product specifications to confirm the scope has a waterproof, shockproof, and nitrogen-purged housing. Field conditions often bring sudden rain, morning dew, and rapid temperature shifts that cause untreated optics to fog internally. Optic designs built on a 1-inch one-piece tube with full nitrogen purging, such as the Hawke Vantage IR hunting scope, prevent internal lens fogging and protect internal components from field moisture. Verifying these specific sealing ratings ensures your optic remains reliable throughout demanding hunts.
