Will We Ever See a Ruger 10/17?

By Justin Stapley | Shooting Director

A couple years ago, I shot a .17 HMR for the first time, a standard Savage bolt-action. I packed it off into the sagebrush, looking for jackrabbits and cottontails. What ensued was one of the most enjoyable rabbit hunts I’ve had in a long time.

Both the accuracy, speed, and impact power of that little round was exhilarating, adrenaline-inducing, and left me grinning from ear to ear. After the hunt, I told my wife I had a new rifle at the top of my firearm list. The look she gave me suggested I was failing to curb the little Ralphy/Red Rider BB gun vibe.

For those of you who don’t know, the .17 HMR came out back in 2002. It’s built on a .22 Magnum casing, necked down to take a .17 caliber projectile. The combination of more powder and less mass leads to an extraordinarily accurate and ranged rimfire cartridge, perfect for small game and varmint hunting. 

The center-mass hits I was scoring on the rabbits were dropping them where they stood (no follow-up shots, no god-awful rabbit screams). And, I was scoring hits on running rabbits way beyond what a .22 could do.

About the only problem I had was learning not to lead the rabbits at a distance. Those little .17 rounds shot so fast that they would impact in front of the rabbit if I led one like I would with a .22. 

My only real complaint with the rifle was the single-action and the relatively small magazine size. Having packed around a Ruger 10/22 since I was a kid, I thought there had to be a good semi-automatic option for the .17 HMR out there, if not a Ruger 10/17 in development.

I was shocked to find the options were limited, almost non-existent, and was told not to trust even the few semi-automatic .17 HMRs that were out there. 

The working theory of most of the firearm industry was that the .17 HMR was too high pressured for a semi-automatic action. This conclusion was mostly due to the recall of Remington’s Model 597 semi-automatic .17 HMR in the late 2000s, which had a bad tendency of shooting the magazine out of the rifle.

The pressure of the bullet would force the action open too quickly, before it had left the barrel, and the expanding gases would escape violently in the wrong direction. I also learned that Ruger canceled its 10/17 development project as a result of the Model 597’s failure.

But these theories were later put to the test and largely debunked by the .17 HMR my wife did end up getting me for Christmas: the Savage A17 (Note: marry a woman who thinks you look cute when you’re grinning like a total moron). Savage was able to solve the problem of high-pressure blowback by building a new delayed-blowback action system from scratch. 

To put it in simplest terms, they fashioned an interrupter lug that holds the bolt in place until the carrier itself moves back from the pressure of the fired shot. The weight of the carrier moves past the interrupter lug and loads another round in the chamber. This system delays the action just long enough to ensure the projectile has left the barrel and expelled the high-pressure gases.

I love my Savage A17, but it’s just not a Ruger. While it uses a similar rotary magazine, the mag release is far less intuitive, and you really have to press hard to make sure the magazine clicks when you insert it, or it will fall back out.

I’ve also found the A17 needs a lot more consistent maintenance to keep it from jamming up. And, I’ve even noticed that spent cartridges sometimes don’t get ejected properly, and the rifle doesn’t seem to have cycled properly at all (I don’t know if it’s carbon build-up, a poor extractor, or simply the delayed-blowback action being too delayed).

Granted, I experienced all of this after new rifle range trips, and we all know how quickly spent brass gets out of hand on trips like that.

So, don’t get me wrong. It’s a fantastic rifle. As long as I give it the care it needs, most of the issues above don’t show up until after a hundred or so rounds have been put through it (and let’s face it, it’s still a rimfire). If my Ruger 10/22 hadn’t spoiled me all these years, I probably wouldn’t know the difference.

And that brings me to the point of all of this. Now that Savage has made the impossible possible, when are we going to see the Ruger 10/17 pop up in the catalog? Unfortunately, the answer may still be never. And, I’m not entirely sure why.

I have actually brought this up in various Facebook Ruger groups, and the replies often go one of two different directions (I’ve heard nothing official though).

The first argument is that the Savage A17 is little more than a novelty rifle.  While its delayed-blowback operation makes a semi-automatic .17 HMR possible, it may not be truly effective nor efficient enough to inspire similar technologies in other rimfire firearms.

The second argument is that the A17’s system is too unique to duplicate before the patent expires. 

As for the first argument, while the A17 does seem to have its annoying ticks, it’s not that ineffective. Most of what I’ve experienced, I’ve experienced with my 10/22 as well (granted after several hundred more shots).

And, I’m sure given another few years or so, the A17s that come out of Savage’s factories will probably experience these issues less and less (they’ve already improved the magazine release). If anything, it’s the lack of competition on the market that’s probably slowing innovation.

To the second argument, delayed-blowback technology is nothing new. While Savage has gone about it in a very unique way, that’s not to say there aren’t similar (but different) ways to do it or that there aren’t better ways to build a similar action. 

Whatever the actual reasons for Ruger’s reticence to re-open its 10/17 program, I sure hope someone at that company can convince them to move past those reasons. The A17 is just similar enough to a 10/22 to make sure that little tick is always going to be there in the back of my mind. If Ruger ever made one, I would probably pounce pretty quickly on a Ruger 10/17. Until then, I’ll be walking the sage with what I’ve got, rabbits beware.

Self-Defense: Is Stopping Power a Myth?

By Justin Stapley | Shooting Director


I’ve been a .40 S&W guy my whole life. My thought process has always been that it’s an excellent middle ground between the .45 ACP and the 9mm. The .40 S&W maintains a respectable level of power yet still allows increased ammo capacity and decreased recoil – and it has great stopping power.

Until a few years ago, my fellow shooting enthusiasts and firearms instructors supported this theory. In 2014, the FBI shocked everyone by announcing a return to the 9mm as their standard-issue round. For justification, the FBI pointed to in-house studies , documented in this FBI Executive Summary, which concludes that “Handgun stopping power is simply a myth.”

Since then, a lot of organizations and individual gun owners have adopted this mentality – that stopping power is a myth. The growing belief is that the only meaningful considerations for ammunition type are capacity, penetration, and light-recoil. I’m still a .40 S&W guy because I figured one study is one study. But I am often hard-pressed to defend myself against claims I’m sacrificing speed, accuracy, and ammo capacity with no benefit gained.

Eventually, I got serious and started trying to learn more about the FBI’s findings. I also did some heavy reading on traditional understandings about the idea of “stopping power.” In this article, I’ll lay out what I’ve found.

My Findings

While the FBI Executive Summary claims their findings debunked the idea of stopping power, that isn’t necessarily the proper conclusion to draw from their data.

The data, and the administrative assertions of the FBI, point to the reality that stopping power is and continues to be highly misunderstood. Many of the diverging opinions and conclusions surrounding the FBI findings result from different ideas of what stopping power is.

What is stopping power?

When the FBI Training Division said stopping power is a myth, and when marksmen and shooters repeat this claim, they’re defining stopping power as stopping somebody in their tracks, or even knocking them back. If this were what stopping power was, the FBI wouldn’t have needed to debunk it.

Every learned and knowledgeable marksman knows that the movie magic of somebody getting knocked back – when shot – as if kicked by a mule is laughable. And, most marksmen recognize that the chance of dropping an assailant dead with a single shot is highly improbable. It should be evident that stopping power means more than these ideas, or it wouldn’t be something serious marksmen have ever discussed.

Stopping power is better defined as the ability to effectively and swiftly incapacitate (stop) the assailant and end the altercation. More specifically, it relates to the combination of several ballistic factors, including tissue displacement and transfer of energy leading to trauma, shock, and hemorrhaging.

What the FBI findings actually point to is a conclusion that speed and accuracy play a much more substantial role in determining stopping power than was previously believed. Rapid and precise placement of small, high-speed projectiles to a lethal area has more stopping power than scattered and slower placement of large, low-speed projectiles.

Is it ammunition-based?

This is the part where the FBI Executive Summary and its defenders make too bold of a claim. The actual performance of various ammunition doesn’t point to stopping power being a myth; it points to a more accurate conclusion that a larger round does not grant more stopping power absent good training and marksmanship skills. If a marksman can place larger projectiles rapidly and precisely, then there is more tissue displacement, more transfer of energy, and more stopping power.

The reason the FBI, and other organizations that followed their lead, went back to the 9mm, truly relates less to the superiority of the round and more to the cost and logistics of effective and constant training. While the FBI Executive Summary claims differently, the reality of actual bullet performance indicates their decision related more to the cost of larger ammunition and the more advanced and in-depth marksmanship training required to get effective use out of larger rounds.

Ultimately, based on the history of ammunition development and stories of smaller projectiles proving to be less effective, what the FBI really concluded was that the modern improvements to the 9mm made it good enough. While the FBI Executive Summary declares the 9mm is superior and that stopping power is a myth, they don’t adequately back that up.

The ammunition performances they cite, the lack of insight they provide into the administrative decision process for abandoning the.40 S&W, and the history of ammunition development and use over the last century-and-a-half should make all marksmen cautious of accepting the assertion that “stopping power is simply a myth.”

Personally, the FBI study and the new debate about stopping power it unleashed informed me more about what it is – but it doesn’t force me to conclude that I should dump the .40 S&W.

As an individual, I have very different considerations when compared to a large organization. How much time do I dedicate to training? How natural are my marksmanship skills? What gun works best for concealment or feels good in my hand (and what ammunition options are there for that gun)? What kind of gun/ammunition did I grow up shooting? Do I flinch or anticipate when shooting? Am I “recoil sensitive”? Do I anticipate the recoil or have sympathetic grip reflexes in response to the feeling that the gun might fly out of my hand?

The definitive conclusions of the FBI Study are that shot placement is the underlying factor in lethality. So yes, all of the above considerations have a more significant impact on stopping power than the size of the bullet. If, for whatever reason, I can’t shoot fast and accurately with the weapon and ammunition I’m currently using, then yes, switching to a 9mm,.380 ACP, or other smaller caliber would grant me more stopping power than I currently have.

But this doesn’t mean bullet size doesn’t matter. If I can put three rapid shots on top of each other at ten yards or more with my .40 S&W than I do have more stopping power than someone who can only do the same thing with a smaller round.

In case you were wondering, I’m still a .40 S&W guy. Constant self-assessment has led me to conclude that my skill is good enough to allow my original thought process to remain relevant. But I am much more aware of the necessity to maintain my marksmanship while carrying a larger round.
