The Savage B.MAG is a bolt-action rifle chambered specifically for the .17 Winchester Super Magnum (.17 WSM), a rimfire cartridge that pushes a 20-grain bullet at around 3,000 fps. The 22-inch heavy stainless steel barrel, 8-round center-feed rotary magazine, and AccuTrigger system are the standout mechanical features.

Detailed Features 

 
The AccuTrigger is adjustable for pull weight, letting the shooter dial in a crisp break without gunsmithing. Lighter pull weight improves consistency for accuracy-focused shooting. The heavy stainless barrel contributes to accuracy by resisting heat-related point-of-impact shift during extended range sessions and by adding rigidity. 
 
The center-feed rotary magazine feeds reliably and reduces the chance of feed-related malfunctions. The B.MAG action uses rear locking lugs in a compact design scaled to the .17 WSM cartridge. Thread-in barrel headspacing allows for easy adjustment. 
 
.17 WSM has a flatter trajectory and higher velocity than .17 HMR or .22 LR, making it useful for varmint shooting at longer rimfire ranges. 
 

Usage Scenarios 

 
The B.MAG is purpose-built for small varmint hunting at ranges where .17 HMR or .22 LR runs out of steam. Squirrels, prairie dogs, and rabbits at 100-200+ yards are the primary applications. Competitive precision rimfire shooters also use it for its accuracy potential.

Owners of the Savage B.MAG generally lead with accuracy. The .17 WSM cartridge's flat trajectory and high velocity make it capable at ranges where standard rimfires struggle, and most owners report the rifle delivers on that potential with quality ammunition.

The AccuTrigger gets consistent praise for its crisp, adjustable pull, which directly affects shot-to-shot consistency. This is one of the features that distinguishes the B.MAG from less expensive rimfire rifles.

Build quality is viewed positively. The combination of stainless steel barrel and quality construction gives owners confidence in the rifle's durability.

Ammo availability is a genuine concern that shows up regularly in discussions. .17 WSM has a smaller market than .22 LR or .17 HMR, and buyers in some areas report difficulty finding it consistently. This is worth considering before purchase.

A subset of owners has reported intermittent cycling or ejection issues with specific ammunition batches. These reports are not universal but appear often enough to suggest the action can be picky about ammunition selection. Most users resolve this by finding a brand that works reliably in their specific rifle.

Overall, the gun is valued for accuracy and the AccuTrigger system, with the caveat that ammo sourcing requires more planning than for more common rimfire calibers.
