Detailed Features 

 
The thumbhole stock gives left- and right-handed shooters the same grip geometry, which helps with shot-to-shot consistency. Savage's AccuTrigger is adjustable from 2.5 to 6 lbs., so you can set it lighter for bench work or leave it heavier for hunting in the field. 
 
The carbon fiber wrapped barrel keeps weight down without giving up barrel stiffness, and the threaded muzzle accepts suppressors or other muzzle devices. The included 20 MOA Picatinny rail gives you built-in elevation offset for long-range optics setups. 
 
Works well for small game hunting and target shooting. The .22 WMR chambering hits harder than .22 LR at distance while still being relatively easy on the wallet for practice.

Owners of the Savage B22 Timberlite in .22 WMR generally rate it well, with a few recurring complaints worth knowing before you buy.

Accuracy comes up most often in positive reviews. Shooters report consistent groupings at distance for a rimfire, which makes it useful for both small game and paper targets. The thumbhole stock design gets credit for comfortable hold and stability. Buyers also appreciate how light it is for a rifle with a carbon fiber barrel — easier to carry on long hikes than traditional stainless setups.

On the critical side, some owners find the trigger heavier than expected out of the box and need to dial it down before it feels right. Magazine feeding issues show up occasionally in feedback — not widespread, but enough to be a known thing. Aftermarket support is thinner than for more common rimfire platforms, which limits customization options. A few buyers also feel the price sits slightly high relative to comparable .22 WMR bolt guns.

Overall it's a solid rimfire rifle that earns its reputation for accuracy, though the trigger and magazine feed are worth checking early on.
