About this product
The Savage B22 Magnum F LH is a left-hand bolt-action rimfire rifle chambered in .22 WMR that delivers consistent accuracy through a 21-inch button-rifled barrel and Savage's adjustable AccuTrigger system. This platform addresses the often-overlooked need for quality left-handed rimfire rifles in the magnum cartridge category, providing serious shooters with proper ergonomics without compromising on mechanical precision. At 6.8 pounds unloaded, it balances well for off-hand shooting while maintaining the rigidity needed for bench-rest work.
What is the Savage B22 Magnum F LH used for?
This rifle is built for left-handed shooters who need reliable .22 WMR performance for small game hunting and precision range work up to 150 yards. The 21-inch barrel optimizes velocity for the magnum cartridge, while the 10+1 rotary magazine capacity provides practical field utility without excessive bulk. I've found it particularly effective for prairie dog control and varmint hunting where shot distances often exceed standard .22 LR effective range.
How does the Savage B22 Magnum F LH compare to the Stevens 334 in .243 Win?
The B22 Magnum fills a completely different role than centerfire options like the Stevens 334 in .308 Win - it's a specialized rimfire versus a general-purpose centerfire. Where the .243 Winchester delivers over 2,800 fps muzzle velocity for medium game, the .22 WMR operates at approximately 2,200 fps, making it better suited for small game where minimal pelt damage matters. The B22 costs nearly $100 less than the Stevens platform while offering rimfire economy for high-volume shooting.
What does it weigh and what are the dimensions?
This rifle weighs 6.8 pounds with an overall length of 40.5 inches thanks to its 21-inch barrel configuration. The synthetic stock measures 13.5 inches length of pull, accommodating most adult shooters without modification. At 2.3 inches wide at the widest point of the receiver, it remains slim enough for comfortable carrying during extended hunting sessions.
Who is this NOT for?
Right-handed shooters should avoid this platform entirely - the left-hand bolt configuration creates significant ergonomic challenges for standard-right shooters. Those needing more power for coyote or fox hunting would be better served by stepping up to a centerfire cartridge like the Stevens 334 in .243 Win. The .22 WMR also lacks the subsonic ammunition options that make suppressed .22 LR rifles so versatile for tactical training.
What's in the box?
The rifle ships with one 10-round rotary magazine, two-piece Weaver-style scope bases installed, and a basic owner's manual covering disassembly and AccuTrigger adjustment. Unlike some competitors, Savage includes the mounting hardware needed for immediate optics installation - a detail that saves buyers approximately $25-40 in additional parts. The package lacks thread protectors or additional magazines, which are available separately.
Is the Savage B22 Magnum F LH worth it at $328.99?
At this price point, it represents solid value for left-handed shooters needing magnum rimfire performance without custom gunsmithing costs. The included AccuTrigger system alone would add $75-100 to a basic rifle's price if added aftermarket. Compared to converting a right-hand rifle to left-hand operation (typically $300-500 in gunsmith work), the B22 Magnum F LH delivers proper left-hand ergonomics at roughly half the total cost.

Frequently asked questions
- Is it compatible with standard .22 LR ammunition?
- No, this rifle is chambered exclusively for .22 WMR (Winchester Magnum Rimfire) cartridges, which are dimensionally incompatible with .22 LR. Attempting to fire .22 LR in this chamber creates dangerous pressure conditions and will likely damage the firearm. Always verify cartridge designation before loading - .22 WMR measures approximately 1.35 inches overall length versus .22 LR's 1.0 inch.
- Does it fit standard rifle cases?
- Yes, the 40.5-inch overall length fits most standard 42-inch rifle cases with adequate clearance for scopes. I recommend cases with at least 44 inches internal length if mounting larger optics like the Vortex Diamondback 4-12x40. The slim profile also accommodates dual-rifle cases when traveling with a backup firearm.
- How long does shipping take?
- Ironclad Armory processes firearm shipments within 2 business days after FFL verification, with transit times typically 3-5 business days via FedEx or UPS. All shipments require valid FFL information from your local dealer before processing. During peak seasons like hunting opener, allow an additional 1-2 days for order verification.
- Can I return it if there are mechanical issues?
- Ironclad Armory accepts returns within 30 days for mechanical defects verified by their gunsmith team. The rifle must be returned unfired with all original packaging for inspection. Savage's manufacturer warranty covers defects for 1 year from purchase date, with most repairs completed within 2-3 weeks at their service center.
- Does this work with suppressor attachments?
- The barrel lacks threading for direct suppressor mounting, requiring aftermarket threading services costing approximately $150-200 from a qualified gunsmith. Unlike some European rimfires, Savage designed this model primarily for unsuppressed hunting use. For suppressed shooting, consider a dedicated .22 LR platform with factory threading.
