The 2009 record in brief, Savage's delayed-blowback answer in 2015 and its semi-automatics in all three .17s today, and why a manually operated action never had the problem

The chambering of this particular rifle is not recorded with the photograph; the 597 family was made in .22 LR and .22 WMR, and its .17 HMR version was the rifle Remington withdrew in August 2009 (§3.2).

For most of its life the .17 HMR has been a bolt-action and single-shot cartridge. That is not an accident of fashion. In August 2009 Remington told owners to stop using both its .17 HMR ammunition and its Model 597 .17 HMR self-loader, and a companion warning told shooters not to fire the cartridge in any semi-automatic without the gunmaker’s say-so. Savage’s semi-automatic for it arrived in 2015, thirteen years after the cartridge, with a delayed action and a matched load.

The whole episode, document by document, now lives in the hub’s .17 Rimfires dive, Volume 8, which established what this volume could not: the dates, Hornady’s reply, and the one document that names a supplier. This volume summarises it and keeps what belongs to the rifle: why a manually operated bolt action is outside the problem, and what an owner of one takes from it.

3.1.1 Two corrections before the history

The Savage A17 is a 2015 rifle, not a 2013 one. Savage’s launch page for the A17 quotes press coverage headed “Best Products of SHOT Show 2015”, and no page on savagearms.com with “a17” in its address was archived at any time in 2013 or 2014; the earliest model page capture is from March 2015.¹ A 2013 date sometimes attached to the rifle may come from a different Savage event that year: ATK’s announced purchase of the company, on 13 May 2013 (Volume 1).

No A17 recall was found on Savage’s own pages. Savage’s recall page, as archived in August 2015, lists one rimfire recall: the B.MAG bolt, in .17 WSM. Savage’s safety page, as archived in 2019, lists the same.² The .17 dive’s Volume 8 reached the same result independently and adds that no “AccuTrigger recall” belongs in this story either. The documented .17 HMR semi-automatic recall is Remington’s.

3.1.2 The record, in brief

Corrected 19 October 2026. The first edition of this volume called Remington’s notice undated, public by January 2010, and its ammunition supplier unidentified. The .17 dive’s research has dated it and found more.

Mid-August 2009: Remington’s notice. “DO NOT USE REMINGTON 17 HMR AMMUNITION IN SEMI-AUTOMATIC FIREARMS. DO NOT USE THE REMINGTON MODEL 597 17 HMR SEMI-AUTOMATIC RIFLE. Remington has been notified by its supplier of 17 HMR ammunition that 17 HMR ammunition is not suitable for use in semi-automatic firearms.”³ The remedy was a buy-back by coupon: $10 for each returned box of 50, and $200 (synthetic) or $250 (laminate) toward a replacement Remington for a returned rifle. The page itself is undated and first archived on 17 January 2010, but contemporary blog posts were reporting it by 19 August 2009, so it was public by mid-August.⁴
20 August 2009, updated 31 August: the ammunition warning. A separate “17 HMR Ammunition Product Safety Notice and Warning”, still published on Federal’s and Remington’s sites, tells shooters not to use 17 HMR ammunition in semi-automatics “without consulting with your firearms manufacturer”, and says that semi-automatics introduced after the cartridge “have proven to be incompatible” in many cases. It names no ammunition maker and no firearm.⁴
15 September 2009: Hornady’s reply. Hornady, which designed the cartridge, said its ammunition met SAAMI standards and that “the firearms manufacturers are solely the ones responsible” for deciding whether a firearm is safe with it.⁴
December 2011: the supplier, alleged. A federal class action filed in Columbia, Tennessee, as reported at the time, claims the 597 HMR “explodes” with the ammunition of co-defendant Cascade Cartridge/CCI. That is an allegation in a complaint, and the only document found that names a supplier; its outcome was not found.⁴

Three features of the record matter more than its dates. It came from the ammunition side: Remington did not say its rifle was defective, it said its supplier had called the ammunition unsuitable for semi-automatics. It was general: on its own terms it reached any self-loader chambered for the cartridge. And none of the documents names a failure mode: “not suitable”, “incompatible” and “within specification” are the words; “case-head separation” and “out-of-battery” are owners’ and writers’ words, not the makers’.

3.1.3 Why a blowback action and this cartridge do not mix

No maker’s document gives the mechanism, so this is reasoning from the design of the two systems, and it is labelled as such. The .17 dive’s Volume 8 §8.4 sets it out against the SAAMI figures; the short form is this.

Rimfire self-loaders are, as a class, straight blowback: the bolt is held against the case head only by its own mass and the recoil spring, so it starts to move as soon as the pressure on the case head overcomes its inertia, and the case starts to leave the chamber while pressure inside it is still high. A rimfire case is the weakest case to ask that of. Its head is a thin folded rim with the priming inside the fold, and part of it cannot be enclosed by the breech because the extractor must reach it. The .17 HMR asks that case to do more than any .22: it is the .22 WMR case with a shoulder added and a bullet of roughly half the weight driven considerably faster. The failure the notices imply is the case letting go while the bolt is moving.

Figure 2 — When the action begins to draw the case rearward. A straight-blowback bolt is free to move almost as soon as pressure reaches the case head. A delayed-blowback bolt, such as the Savage A17's, is he… — Figure 2 — When the action begins to draw the case rearward. A straight-blowback bolt is free to move almost as soon as pressure reaches the case head. A delayed-blowback bolt, such as the Savage A17's, is held until pressure has fallen. A bolt action is opened by hand long after the pressure is gone. The curve is schematic: no pressure-time measurement for .17 HMR was obtained. Source: original diagram.

3.1.4 Savage’s answer: delay the bolt, and match the load

Savage’s first semi-automatic .17 HMR addressed exactly the interval in that figure. Its launch page, archived in March 2015, leads with a “Delayed-Blowback Action Specifically Designed For High Performance Magnum Cartridges Chambered In 17 HMR”, with a hard-chromed bolt, a ten-round rotary magazine and the AccuTrigger.¹ The A17 owner’s manual states the purpose in one clause: a “patent-pending delayed blowback action, which prevents the bolt from opening prematurely.”⁵

The ammunition was designed with the rifle. CCI says it “literally built this 17 HMR load around the A17 rifle from Savage Arms”, “optimized for feeding and function in the semi-automatic rifle”.⁶ Savage’s manual recommends it: “For optimal performance with your A17, use CCI A17 ammunition (designed specifically for the Savage A17).” It also asks the owner to keep the bolt lightly lubricated, to let the bolt snap forward rather than easing it, and to hold the trigger back after each shot until the action has fully cycled.⁵

Savage’s own FAQ, dated March 2015, takes a slightly broader line on ammunition: “The A17 will work with all 17 HMR ammunition. However, for best performance, we suggest CCI A17 ammo.”⁷

Set side by side, the two positions trace the whole arc. In 2009 a supplier said no 17 HMR ammunition was suitable for semi-automatics, and a rifle was withdrawn. In 2015, a maker built a delayed action and said its rifle would work with all 17 HMR ammunition, best of all with a load made for it. The difference between the two positions is the delay. One loose end remains on the box: CCI’s A17 load, built for a semi-automatic, carries the same “do not use in semi-automatic firearms without consulting with your firearms manufacturer” line as every other CCI .17 HMR load, a contradiction the .17 dive’s Volume 8 §8.5 reads literally (the maker, Savage, has been consulted) and leaves at that.

Savage now builds semi-automatics in all three .17 rimfires. Its model pages, read on 19 October 2026, catalogue the A17 and A Series rifles in .17 HMR, the A17 Sporter and A Series Target Thumbhole also in .17 WSM, and the A Series Magnum, “Savage’s exclusive delayed blowback semi-automatic action”, also in .17 HM2 (SKU 47700, a 20-inch barrel).⁸ Every one is a delayed-blowback design. None of it bears on the 93R17, which is a bolt action, but it closes the arc: thirteen years after a supplier said no .17 HMR was suitable for any semi-automatic, the answer in steel was the delay, applied across the family.

The Savage that did not need a delay. For contrast, Savage’s long-running .22 LR autoloader, the Model 64, advertises no delay at all; in the far gentler .22 LR it does not need one.

Figure 3 — A Savage Model 64F, the company's .22 LR autoloader. It is an ordinary rimfire autoloader with no delay, the arrangement the A17's delayed action was designed to improve on for .17 HMR.

3.1.5 Why the bolt gun never had the problem

The rifle documented here opens only when a hand lifts the bolt handle. Savage’s manual describes the sequence: after firing, “Pull up and fully rearward on the bolt handle to open the bolt to extract the fired case.”⁹ Between the shot and that lift, the bolt is closed with its handle turned down into the receiver, and nothing in the mechanism allows it to move. By the time a shooter can physically lift the handle, the pressure pulse, which lasts on the order of a millisecond, is long over. Extraction happens with the case at rest, not in motion under pressure.

That is the whole difference, and it is why the 93R17 was never part of any of the history above. Any .17 HMR ammunition made to the standard is appropriate for the rifle, including the CCI A17 load, which simply fires as a fast 17-grain cartridge.

Two cautions keep that from becoming complacency.

Case failure is not unique to self-loaders. Savage’s own manual for this rifle tells the owner what to do if “what appears to be gas pressure/residual powder” comes from the bolt area: “this may be what is known as ‘BLOW BACK’ … we recommend trying a different brand of ammunition”, and it adds that “wearing safety glasses will protect your eyes”.⁹ A bolt action removes the timing problem. It does not make a defective case safe, and eye protection is not optional with any rimfire.
The one rimfire recall Savage has published concerns a bolt action. The B.MAG in .17 WSM was recalled because its bolt “may inadvertently catch the safety button and slide it forward into the ‘fire’ position”; the fix was a new bolt handle and a blunter bolt cap.² That is not this rifle’s action. But Savage’s current manual for the Mark II and Model 93 carries the same check, in capitals, as the first item of routine maintenance: “BE SURE THE BOLT HANDLE OR CAP DOES NOT HIT THE SAFETY WHEN CLOSING THE BOLT.”⁹ It costs nothing to do, and Volume 5 puts it in the inspection routine.

3.1.6 What an owner takes from this

Feed the 93R17 any factory .17 HMR. The semi-automatic problem does not reach a manually operated action.
Do not reason from the A17 to other self-loaders. The A17 answer is a delay plus matched ammunition. A self-loader chambered for .17 HMR without an equivalent design is exactly the rifle Remington withdrew.
Treat vented gas at the bolt as a stop signal. Savage’s instruction is to change ammunition; the hub’s practice is to stop, clear the rifle, and look at the case before firing again.

3.1.7 What could not be verified

The exact posting date of Remington’s notice. It was public by 19 August 2009 on contemporary reports; the page itself is undated (.17 Rimfires, Volume 8).
The ammunition supplier Remington cites. Named only as an allegation, in a 2011 complaint whose outcome was not found.
When the Model 597 was first offered in .17 HMR, and how many were sold.
Whether other makers’ .17 HMR self-loaders of the period were withdrawn or modified. None was confirmed from a maker’s own page, so none is named.
Any Savage recall, service bulletin or product change concerning the A17. None appears on Savage’s archived recall pages.
Pressure-time data for .17 HMR. The timing figure is schematic for that reason. SAAMI’s pressure figures for the cartridge are in .17 Rimfires, Volume 3; a pressure-time curve is not.
