The Savage B22 Magnum FVSS is a bolt-action rimfire rifle chambered in .22 WMR. The 21-inch barrel gives the cartridge room to develop velocity, which matters when you're stretching the .22 Magnum out to longer distances on small game or varmints.

Features 

 
Savage's AccuTrigger is the main draw here. It's adjustable for pull weight and has a built-in safety tab that prevents the trigger from moving unless you apply direct finger pressure — so you can set it light without introducing a safety concern. That adjustability is genuinely useful for dialing in a consistent release. 
 
The bolt cycles smoothly and feeds from the 10-round detachable rotary magazine. Stainless steel receiver and synthetic stock handle wet weather without concern about corrosion or stock warping. Receiver is drilled and tapped for scope mounts. 
 
At 6.2 lbs it's a reasonable carry weight for a full-size rimfire. The 21-inch barrel is longer than most rimfire rifles in this category, which does add a few inches to overall length. 
 

Usage 

 
This rifle is well-suited to small game, varmint control, and general-purpose rimfire shooting. The .22 WMR hits harder and flatter than .22 LR at distance, and the B22's accuracy makes it practical for field shots where a .22 LR would be marginal.

The Savage B22 Magnum FVSS gets consistently positive marks, with a few minor points that come up across user discussions.

Accuracy is the most frequently praised attribute. Owners report tight groups at extended distances for a rimfire, and credit goes to both the 21-inch barrel and the AccuTrigger. The AccuTrigger specifically draws a lot of comment — shooters appreciate being able to set a light, crisp pull that's still safe to carry. Build quality gets solid marks; the stainless steel and synthetic construction is described as sturdy and weather-resistant.

On the critical side, some owners note the rifle is heavier than other rimfire options, which can be noticeable on long hunts. Magazine capacity at 10 rounds draws occasional criticism from those who'd prefer more. Neither complaint is serious enough to override the positive reception, just worth knowing before buying.

Overall it's well-regarded as a capable, accurate .22 WMR bolt gun at a fair price.
