Savage B22 Magnum F 22 WMR 21in 10rd Black Synthetic
Pros & cons
What works
- AccuTrigger is user-adjustable from approximately 2.5 to 6 pounds pull weight without a gunsmith.
- Weighs 5.79 lbs — nearly a full pound lighter than many comparable centerfire varmint rifles.
- 21-inch button-rifled barrel provides consistent sub-MOA accuracy with quality .22 WMR ammo.
- 10-round rotary magazine feeds reliably and sits flush with the stock for a clean profile.
Trade-offs
- Barrel is not threaded from factory — adding a suppressor requires a $125+ gunsmithing job.
- Proprietary magazine design limits aftermarket spares; extra magazines cost around $35 each.
- Synthetic stock has some flex in the forend under heavy bipod loading, which can affect point of impact.
- .22 WMR ammunition averages 35 cents per round, making practice sessions 3-4x more expensive than .22 LR.

About this product
What is the Savage B22 Magnum F?
The Savage B22 Magnum F is a bolt-action rimfire rifle chambered in .22 Winchester Magnum rimfire (22 WMR) designed for varmint control and precision shooting. It combines Savage's user-adjustable AccuTrigger system with a 21-inch button-rifled barrel and an ergonomic synthetic stock for consistent field accuracy. At 5.79 pounds and 39 inches overall, it offers a balanced platform ready for optics mounting out of the box.
What is the Savage B22 Magnum F used for?
The Savage B22 Magnum F is designed for small game hunting, varmint control, and rimfire target training where the extended range and energy of the .22 WMR cartridge is required. Its bolt-action design and adjustable trigger allow for precise shots out to approximately 125 yards on appropriate targets, making it suitable for prairie dog towns or coyote sets where noise discipline is a factor compared to centerfire rounds. The synthetic stock and matte finish resist weather during all-day sits in a blind or truck rack.
How does the Savage B22 Magnum F compare to the Ruger American Rimfire Magnum?
The Savage B22 Magnum F provides a superior stock ergonomics package and trigger system, but the Ruger American Rimfire Magnum offers greater aftermarket support. Where the Savage uses a proprietary 10-round rotary magazine and an integrated, adjustable AccuTrigger, the Ruger utilizes more common magazines and a basic, non-adjustable trigger blade. For a shooter prioritizing out-of-the-box ergonomics and a crisp, adjustable trigger pull, the Savage is the better rifle; for those wanting to customize with aftermarket chassis systems, the Ruger platform is more flexible.
What does it weigh and what are the dimensions?
The Savage B22 Magnum F weighs 5.79 pounds (92.64 ounces) and measures 39 inches in overall length with a 21-inch barrel. The sporter-profile barrel has a 1:16-inch twist rate, optimized for stabilizing the typical 40-grain .22 WMR projectile. This weight and balance point makes it easy to carry afield but stable enough for off-hand shots on running pests like ground squirrels. For hunters considering different action types, our Stevens 334 in .308 Win offers a centerfire comparison at 6.8 pounds.
Who is this NOT for?
The Savage B22 Magnum F is not for shooters seeking a plinking rifle for casual .22 Long Rifle use or those operating under strict budget constraints for ammunition. The .22 WMR cartridge costs roughly 30-40 cents per round versus 8-10 cents for .22 LR, making sustained fire training significantly more expensive. It's also a poor choice for those wanting a takedown or compact truck gun, as its 39-inch length doesn't break down; a shooter needing that portability should look at a carbine or pistol-caliber platform instead.
What's in the box?
The rifle ships with one 10-round detachable rotary magazine, a standard 1-inch scope mount base ring set, and the necessary Allen wrenches for trigger adjustment and scope base installation. You will not find thread protectors, sling swivels, or a bore snake included—these are considered field accessories you must supply. The packaging is typically a single cardboard box with foam inserts; allow 15 minutes for unboxing and a basic function check before heading to the range.
Is the Savage B22 Magnum F worth it at $328.99?
At $328.99, the Savage B22 Magnum F represents strong value for a dedicated varminter due to its AccuTrigger and out-of-the-box accuracy potential. For comparison, a base-model bolt-action .22 WMR from other manufacturers often lacks an adjustable trigger and can cost within $50 of this price, making the Savage's feature set competitive. If your primary use case is dispatching pests like marmots or raccoons at 75-100 yards with minimal fur damage, this rifle justifies its cost; if you just want a .22 for tin cans, the expense of .22 WMR ammo makes it a poor choice versus a standard .243 Win deer rifle you might already own.

Frequently asked questions
- Is it compatible with a suppressor?
- No, the Savage B22 Magnum F's barrel is not threaded from the factory, so it is not directly compatible with a suppressor. To add a suppressor, you would need a qualified gunsmith to thread the muzzle to 1/2x28 or another common pattern, a process costing approximately $125-$200 and requiring proper alignment. Always consult local NFA regulations regarding suppressor ownership and use before modification.
- Does it fit in a standard rifle case?
- Yes, the 39-inch overall length fits in most standard 42-inch or longer soft or hard rifle cases. I use a Plano All-Weather 42-inch case with foam, which provides adequate clearance for the rifle and a small scope. For transport with optics mounted, ensure the internal width of the case exceeds 10 inches to accommodate the stock's vertical pistol grip.
- How long does shipping take?
- Shipping to an FFL dealer typically takes 5-7 business days from our warehouse in Montana via UPS Ground for the contiguous United States. Processing times add 1-2 business days after order verification. You must provide your chosen FFL dealer's information at checkout; we will not ship without a valid, current FFL on file from the receiving dealer.
- Can I return it if it doesn't fit?
- Firearms sales are final once the transfer is completed at your FFL dealer due to federal regulations. You may inspect the rifle at the dealer before completing Form 4473 and paying their transfer fee; if you identify a manufacturing defect, we will initiate a warranty claim with Savage Arms. Do not accept the transfer if the rifle has visible damage or fails a basic function check conducted by the dealer.
- Does this work with a bipod?
- Yes, the synthetic stock has a flat forend suitable for attaching a standard swivel-stud mounted bipod, such as those from Harris or Caldwell. The stud is pre-installed approximately 4 inches back from the forend tip. Using a bipod does not interfere with magazine insertion or removal, but ensure the bipod legs clear the 10-round magazine when folded.
