The Savage A17 in 17 HMR was American Hunter’s 2016 Rifle of the Year. We weren’t surprised. This little rimfire was the first auto-loader engineered from scratch to handle the pressure of the 17 HMR safely and reliably. The A17 also proved to be very accurate and tons of fun to shoot.
If you like the A17’s award-winning delayed-blowback technology, but prefer to shoot a .22 WMR (Winchester Magnum Rimfire) cartridge, you’re in luck. Savage just announced the A22 Magnum, a new rifle that uses an A17-type action (with innovative interrupter lug), to shoot the .22 WMR cartridge.
The A22 Magnum is chambered for .22 WMR and features the same delayed-blowback auto-loading action as the original A17. The A22 Magnum feature a strong steel receiver, chromed bolt, 10-round rotary magazine, and adjustable Savage AccuTrigger. The A22 employs a thread-in headspace system like Savage’s centerfire rifles. This makes it easier to swap in a match-grade barrel down the line. The A22 also comes with two-piece bases for scope mounts

Advantages of .22 WMR over 17 HMR
We like both rimfire cartridges, but we understand why some shooters may prefer the older .22 WMR over the newer, speedier 17 HMR. Here are some of the advantages of the .22 Winchester Magnum Rimfire (WMR):
1. .22 Caliber bores are easier to clean than .17 caliber bores. Good .22-Cal cleaning rods are less flexy than .17-cal rods and a greater range of jags and brushes are offered for the larger caliber.
2. The .22 WMR makes a bigger hole — this makes your groups easier to see at longer range, and the bigger hole can give you a scoring edge in rimfire competitions.
3. The .22 WMR offers a wider choice of ammo manufacturers and bullet types. If a hunter desires a heavier, non-fragmenting bullet, the .22 WMR may be a better choice.

Ouch. The Ruger American Rimfire (RAR) rifle has only been on the market for a few months, and now some of the .22 WMR and .17 HMR versions are already being recalled. Some of these RARs left the factory without the necessary gas venting port.
Reason for Recall
Ruger American Rimfire rifles chambered in .22 WMR and .17 HMR manufactured between November 17, 2013 and January 8, 2014 were manufactured without a vent hole. This hole should appear just below and behind the serial number on the left-hand side of the receiver. The hole does not serve any function during normal operation of the rifle, but is a safety feature and may help vent gas in the event of a problem such as a ruptured case head or bore obstruction. Rifles are being recalled to add the vent hole to the action.
Which Particular Rifles Are Being Recalled?
Only Ruger American Rimfire rifles chambered in .22 WMR and .17 HMR within the serial number range 830-34831 to 830-43880 are subject to the recall. If your rifle is chambered in .22 LR or falls outside this serial number range, it is not subject to the recall. If you do have a RAR chambered in .22 WMR or .17 HMR, examine the left side of the receiver, just below and behind the serial number. If there is a hole there (Figure 1), then you do not need to return the rifle. If there is no hole (Figure 2), then the rifle should be returned.
If you own a RAR chambered in .22 WMR or .17 HMR that is subject to the recall, contact Ruger. Call (603) 865-3100 or send email to: recall@ruger.com. After verifying that the recall applies to your rifle, Ruger will send out a packing container, detailed instructions, and shipping label so you can send in your rifle FREE of charge. Ruger will then retrofit your rifle and return it to you within one week of the day Ruger receives it.
For RAR owners affected by the recall, Ruger will pay all costs of shipping (both ways). Ruger will also include a free magazine, a $24.95 value, when Ruger returns the rifle. Connecticut residents will receive a ShopRuger.com gift certificate in lieu of the magazine.

Recently, we profiled the all-new, bolt-action Ruger American Rimfire™ rifle. It’s modular, affordable (MSRP $329.00), and it will be offered in three rimfire chamberings: .22 LR, .22 WMR, and 17 HMR. Notably, the .22 versions can use all types of Ruger 10/22 magazines — that’s a huge plus for folks who already own a Ruger 10/22. After this new rifle was introduced, readers wondered how well it functions, and how the accuracy compares to the popular .22 LR bolt guns from CZ and Savage.
GunsAmerica Blog Review GunsAmerica, a leading firearms buy/sell website, managed to get hold of one of these Ruger American Rimfire rifles, chambered in .22 LR. GunsAmerica’s staff put the rifle through its paces at the range, and came away very impressed. The test rifle shot sub-inch groups at 50 yards with Federal Lightning and CCI Stinger ammunition. We expect the rifle would shoot even better with quality, match-grade Lapua or Eley rimfire ammo. CLICK HERE for full GunsAmerica Rifle Review.
Given the smooth-working bolt, crisp 3-lb trigger, and comfortable stock with built-in bedding system, GunsAmerica concludes that this Ruger delivers a lot of performance for the $329.00 price. GunsAmerica’s writers are probably right in predicting that the Ruger American Rifle will be a hot-seller, stealing market share from other low-to-mid-priced rimfire brands (such as CZ):
“With this one new rifle Ruger has propelled itself to the front of the pack of the bolt-action rimfire market[.] While there are other great rimfire bolt guns out there at affordable prices, nobody is going to dispute that the Ruger American Rimfire has leapfrogged the entire market. The rifle is superb, and missing really nothing. These guns are going to fly off the shelves….”

ISSC will soon be shipping its new SPA 22/17 series of rimfire rifles. These rifles all feature a fast, biathlon-style, Straight-Pull Action (SPA). This allows for rapid cycling without having to lift your head off the stock. Watch the video below and you can see how you can easily work the toggle action with thumb and two fingers. ISSC offers the SPA 22/17 in three popular rimfire chamberings: .22 LR, .22 WMR, and 17 HMR. We think the 17 HMR version of this little rifle would be a great “carry-around” varmint rig. And the “Target” model, as chambered in .22 LR, seems ideal for the popular “Rimfire Tactical” game.
The Austrian-made SPA 22/17 is offered in three (3) different stock versions: Wood stock (with raised comb), Polymer sporter stock (with Snabel-style fore-end), and a “Target” model (with a folding, Accuracy International-style thumbhole stock). All variants come with 10-round magazines. The rifles are currently offered in three popular rimfire chamberings: .22 LR, .22 WMR, and .17 HMR. The ISSC SPA 22/17 series of rifles is distributed in the USA through Legacy Sports International.
We’re told that the first shipments of ISSC Spa 22/17 rifles should be arriving by mid-May, with larger shipments scheduled for June, 2013. We expect these rifles to be pretty popular, so you may want to get in line. Here’s a video from Legacy Sports showing how the straight-pull actions work:
ISSC is located in Ried, Austria. The company’s design and engineering work is accomplished at the company’s ESC subsidiary, located in Ulm, Germany.

Winchester is producing four new types of rimfire ammunition for 2011. Three of the four products should be of great interest to varminters, with new high velocity, high expansion, and lead-free designs. Winchester is also introducing its M-22 bulk pack .22LR ammo, designed for use in mag-fed semi-autos.
Varmint HV in .22 Magnum Rimfire SPECS: 30gr tipped V-Max bullet, 2250 FPS
The Winchester Varmint HV line of .22 WMR ammo has proven very popular, and this year Winchester adds a new version for varminters who prefer a plastic-tipped bullet. The latest Varmint HV round features the accurate and explosive 30gr V-Max bullet. With a V-Max loaded to an impressive 2250 fps, this gives you near 17HMR velocity, with a heavier bullet for added hitting power.
Varmint HE 3-in-1 Segmented .22LR SPECS: 37gr plated HP, 1435 FPS
The unique 3-in-1 segment design, exclusive to Winchester, features a 37gr plated HP fragmenting expansion bullet pushed at 1435 fps. This “progammed” hollow-point bullet fragments into three forward segments, plus a solid rear core that gives more penetration (and energy). “Without a doubt, Varmint HE ammunition provides explosive impact,” said Brett Flaugher, Winchester’s Marketing VP. “The 3/1 segmenting design makes this product truly innovative, but unlike other high-energy bullets on the market, our new 3/1 fragmenting design allows initial impact shock, and deep penetration resulting in maximum terminal effect.”
Varmint LF (Lead-Free) 17 HMR SPECS: 15.5gr NXT tipped lead-free bullet, 2550 FPS
For 2011, Winchester is introducing a new 17HMR version of its popular Lead-Free (LF) rimfire ammo. The new 17HMR LF shoots a lightweight, 15.5gr tipped NXT bullet at a blistering 2550 fps, making this some of the highest-velocity rimfire ammo you can buy. Along with the new 17MHR LF, Winchester’s LF rimfire line includes lead-free .22 WMR and .22LR LF ammo.
M-22 Ammo for .22LR Tactical Trainers SPECS: 40gr, Blackened Copper-plated Lead Bullet, 1255 FPS
New this year is Winchester’s M-22 line of affordable .22LR ammo. This is designed to function well in large-capacity stick magazines. If you are shooting one of the .22LR tactical-style semi-autos such as Smith & Wesson’s MP15-22, this ammo would be a good choice. It features a blackened, copper-plated 40gr lead bullet, and is available in 1000-count bulk packs.
Marlin will produce a new line of affordable bolt-action, rimfire rifles in 2011. Dubbed the Marlin XT Series, the new rifles will be offered in 17 HMR, .22 LR, and .22 WMR, all with a variety of barrel and stock configurations. We’re pleased to see the XT line fitted with Marlin’s signature Micro-Groove barrels which have proven quite accurate in Marlin’s rimfire lever guns. Sorry, no prices have yet been announced, but XT rifles will be priced competitively in the “affordable” market segment.
The good news is that Marlin has fitted a new adjustable XT Pro-Fire® trigger system in the entire XT line. This trigger is user-adjustable from 3 pounds to 6 pounds pull weight, with “virtually zero creep” according to Marlin. A 3-lb pull is acceptable on this kind of rifle. The bad news, in our opinion, is that Marlin has fitted its triggers with a Glock-style “trigger safety” insert that must be pulled back before the trigger can be engaged. The “trigger safety” may please Marlin’s lawyers, but we have found such devices annoying at best, and unreliable at worst. In fairness to Marlin, perhaps it has executed the trigger-shoe safety system in a better fashion than some other manufacturers. Let’s hope so.
17 HMR Version Available with Laminated Thumbhole Stock
Among the many XT offerings, we think the Model XT-17VLB may be the best option for serious varminters. Chambered for the accurate, 2500 fps 17 HMR cartridge, this rifle features a handsome, ergonomic thumbhole stock. The added effective range of the 17 HMR gives the varminter more options in the field. As with other XTs, the receiver comes drilled, tapped and grooved for mounting scopes.
Two New XT Youth Models
Among the new XT offering are two new XT Youth Rifles — the first Marlin rifles designed specifically for younger shooters. The XT Youth rifles feature a shorter length of pull, shorter trigger reach, smaller pistol grip and a raised comb, making it easier for young shooters to maintain the proper sight picture.
