I remember my German machinist instructor once said "Your project is satisfyingly done. I have no adequate reason nor time to criticize it." I was walking on air that day.

@@chpruc Just to make sure im understanding the 'nor time' part, was he inferring, that with enough time studying it, he could of found something to criticize it? (It was done well enough there wasn't any real flaws)

@@Gruvmpy pretty much. That's how he spoke. Basically he said he didn't think it was worth time to look for flaws

As a german engineer myself I can confirm that we actually have the saying "Not complaining is enough praise". Completely unironically (as you would probably expect).

Exactly what Savage adopted into the new Impulse

Yes, they are. I own a pre-war Heym drilling. High-end double rifles and drillings have historically been their speciality, which of course only a very high quality company is able to manufacture. They are credited for some very important patents throughout the years, one of them being the hammerless drilling action, I believe. I also have a custom SR20 in 7mm rem mag, and.. well, I've had a lot of Heyms, lol.

As everyone should

I worked at the Hanau R&G an we got the chance to visit the factory twice awesome factory, still hand fitting is being done mixing cnc with old world tradition. Where was your dad stationed

those simple things, eh

Superdude70 It looks pretty basic, higher end “classy” rifles don’t come with a picatinny rail up top. This looks like a Low-mid tier rifle alongside Rem 700, Sav M10, etc.

TMoD7007 while the manufacturer may usually make high end rifles, this is definitely not one. This appears to be a $600-700 rifle on gun broker which puts it in the low-mid tier budget rifle range. That’s not a bad thing. I checked the price of other Heym’s and some of their double rifles went for $20k and up. So I’m guessing this was their “budget line” rifle with a basic stock, questionable mounts (factory scope mounts are usually trash), and less fitting than their more expensive rifles. Blaser rifles are what I’d consider to be semi high end tier and a much better choice for straight pull bolt guns. But The best looking gun I’ve seen is my Uncle’s Browning X-Bolt White Gold Medallion and this Heym doesn’t come close at all.

@@BuggaBoy69 They mount your picatinny rail, shoot it in, and get you a target grouping with that. Hard to imagine its low quality. Also more around 2k on gunbroker, dunno which gun you were looking at lmao

@@BuggaBoy69 Yeah, no. This is a $2000 rifle at the low end.

@@Larcona_ you looked up a gunsamerica listing for the deluxe version of this rifle that includes a $1000+ leupold scope and is in .375ruger which is one of the more rare calibers for this rifle.

Exactly. Tons of pneumatic systems use that locking system.

@@charlesperry1051 along with all sorts of Hydraulic disconnect fittings!

Ugg! ...along with lots of hydraulic quick-connect fittings that have brindled and peened ball bearing locking surfaces... spherical locking surfaces are an unnecessary concentration of locking forces.

It was used in 22lr rifles for ages

Zündapp and maico used a simular thing for thier gearboxes.

another common use is actually locks. like lock locks. with keys and so on. Most high end padlocks physical locking is done by two large ball bearings being pushed out by a locking cylinder. The shackle has two half round cuts and the locking cylinder has another two cuts. On open the cylinders cuts line up with the bearings, thus allowing them to slide in on shackle being opened. On locked position rotate the cylinder 90 degrees and it is a solid cylinder wall lining up. It pushes the bearings out to the shackles matching cuts and it ain't coming out. Also ball bearings are extremely secure way to lock physically. As symmetric objects they don't have prone weak points like say sharp cut edges on lugs. The force would have to either push through the whole bolt, compress the plunger or rip apart the locking recesses on the barrel extension. Frankly I find it odd not more people use this method. Since it is also economical. No getting machining to cut complex bolt with lugs and so on. Just call the nearest reputable ball bearing supplier and ask for bearings of suitable material, hardness and dimension on order. rest of the locking system is either cylinder stock, lathing or drilling holes of various sizes. Extremely simple to make. As said the real hard part is the bearings, which are actually really really hard to make well. Luckily there is whole industrial consortiums whose whole business is to provide ball bearings of all possible sizes and materials to anyone who pays them money. Meaning the hardest item to make is of the shelf item.

@@aritakalo8011 that's the first thing I thought to but the hydraulic push fittings make sense too.

The detachable trailer hitch on one of my cars works just the same. 4 or 6 not too big bearing balls are good for pulling over two tons. (I refer to bbs as bearing balls, because balls without a bearing race are just... balls, only the complete assembly is a bearing)

i was thinking quick connect air hose couplers

@@michaellesak6912 same here. Use them every day at work.

Well the law dictates that you cant have more than 3 rounds in your Semiauto Rifles. Maximum Magazin capacity is 10 rounds and this count for all Rifles (Up to 20 For Pistols)

@@uwesca6263 danke!!

You could even carry around a pouch of ball bearings and swap out old or damaged ones instead of buying a whole new bolt. you could spin them around and find any damage on individual balls well before the whole system failed and it would cost pennies to fix.

@@MrLoobu Ssshhhh most of these "manufacturers" Would go bankrupt with these ideas.

Machining the holes in the bolt that hold the balls from falling out would be hard to do at home. You need a round chamfered hole that matches the radius of the ball bearings, on the inside of the bolt.

@@MrLoobu bolts gonna break before a ball bearing

@@ionstorm66 as a home machinist, I have to say that it would not be that difficult. Using an indexer on a milling machine you would drill the six holes. Then a two part chamferring tool, with the properly ground head attached after being inserted through the opposing hole to finish.

Try the Steel Action HS, even here in Germany it is not as well known as the Heym SR30, the Merkel Helix or the Blaser R8.

Google Larsen Winterros shotgun. Marvel at the beauty of that thing. Then go ask people if they know about this cool lever action shotgun made in the 1880s’, and the say no when someone eventually guesses winchester 1887. That should net you some considerable gun nerd cred.

leo_hunts Hey cheers for the heads up on that rifle. Really cool stuff.

I really hate Twilight Zone instances, but cool story.

Curious, indeed. Maybe it is because the SR30 started to hit the market in 1996. 🤷🏼‍♂️

Anschutz also makes a .17HMR sporting rifle using the same system but it's eye-wateringly expensive for a rimfire.

That’s right, my Anschütz 1727 F does the same. Some differences: The balls on the Fortner action (that is what the Aschütz Rifles with “F” use) are behind the magazine. Advantage: The length of pull is reduced, similar to a Lee-Enfield (locking lugs in the rear). To be noted: The length of pull on the .17 HMR model is a little bit longer. There is no decocking feature: You can use the “unlocked” position of the bolt handle (bolt completely in the front still) to hold the striker back or to smoothly lower the striker by guiding the bolt handle with pressed trigger. So this is only a feature for going easy on the rimfire striker, without a round in the chamber. I wonder how the forces on the Heym are. Although the operating forces in the Fortner action are not that high, for a continuous usage you have to practice your index finger.

I did not know that's how they locked, I just figured it was a standard straight pull configuration but miniature. Makes a lot of sense, thanks!

I agree, although this is cool and pretty simple system, this makes the bolt to have about six more moving parts than regular rotating bolt. Which means: 1) more places to get dirt stuck into and also much harder to clean - i dont see any way how to get inside the hollow bolt 2) if any of the six rolling bearings were to fail, it makes the system much more prone to lock failure, given the nature of push-and-roll lock. I know this is very unlikely, but i can imagine some of the bearings missing, which would make rest of the bearings lose their locking pressure and general failure. On the rotating two-lug bolt this can hardly happen, you can have either two lugs lock or none at all and e.g. if one lug was cracked and is missing, second still locks in the place just as same as before, just with more pressure applied.

yes

Thank you. I was wondering why militaries still preferred manually rotating bolt actions. I was watching this video wondering if I would I ever want a modern manually rotating bolt-action since the modern straight-pull bolt actions seem at first glance to be superior. But if the small moving parts in these operating systems make them more prone to malfunctions in field conditions, that explains why they are not widely promoted as the future of bolt-action firearm designs in general. I imagine that such problems can be overcome with further engineering, and given the popularity of such rifles in the European sporting market development of straight-pull bolt actions will continue, perhaps to the point of surpassing the more common manually rotating bolt actions for hunting and military use. Although militaries are increasingly leaving manual actions behind altogether and replacing bolt-action rifles with semi-autos, due to legal restrictions the civilian and hunting market for manual actions will remain for the foreseeable future.

Are metric more expensive?

har har @@SW-ii5gg

No such thing as minimal cost on a Heym

Wonder if you could have the bearings pushed into position by a wider-than-usual cylindrical firing pin: Pin traveling forward locks the bolt and fires, and the bearings would prevent an out-of-battery discharge by blocking the pin if not seated properly.

@@ToastyMozart That's exactly what I thought was going on here the first moment I saw the bolt - it's a no brainer mechanical safety; the firing pin either will or will not fit through the gap between the ball bearings depending entirely on whether or not the bolt is in battery, if it physically can't fit then it can't fire. Now, if we just mill a small slot through one wall of the bolt, use this slot to attach a either an operating rod to which attaches a piston style gas system, or an AR15 style 'DI' nipple thing gas system - honestly shouldn't require very much gas pressure, just enough to overcome the firing pin spring(to unlock the bolt), then push the fully unlocked bolt(in other words, no drag from the friction of, say, turning torsional motion into linear motion, like rotating a bolt...) open against the spring pressure of, preferably, an AR18 style receiver-integrated dual recoil spring, to keep the operating parts of the rifle as compact and centralized as possible(I.E., no garbage AR15 style buffer tube hanging off the back - I'll take the mags though). Maybe have Ruger manufacture it since casting is MUCH cheaper than forgings or billet, and they may just be the best in the industry at casting, not to mention just making high quality budget firearms in general(think about it - the US military couldn't make the M14 worth a damn - but, Ruger managed to! LOL), which is where you really need to win to survive in the firearms industry. Of course, the high end stuff could be gold billet if you can write the check for it. Now, just figuring out how the hell to get anyone to buy one when, 1) it isn't an AR, 2) it isn't a plastic striker 9mm, 3) it isn't an AK, 4) it isn't a 1911, and 5) "...well, what is it?"

I had the same thought one annular grove for the 6 balls to lock into would be easy to machine.

Fair point, the system is unique in that unlike typical use of ball bearings (outside of firearms of course :p) they're not actually needed to spin under pressure while locked in battery, so 6 individual recesses prevents any rotational as well as the normal telescopic bolt movement

i would not bet my life or my health on a blaser!basically no margin of safety,if anything goes wrong!

@@pebo8306 I understand your concern, but in practice the R8 is an extremely safe rifle. The locking lugs create a very large locking surface as compared to most other straight pull rifles. There's been instances of accidents with extreme over pressure that didn't cause the rifle to fail dangerously, like firing a .308 in a .270 barrel (which obviously destroyed the barrel and the bolt). I'd be slightly more concerned about an R93, as I know about an instance of a dangerous failure there. I'm sure you could make a n R8 fail dangerously if you really tried, but it would likely have to be under somewhat extraordinary circumstances.

It's used in a lot of locks on hydraulic lines, almost 1:1 to the lines I used to hook up to our tractors back on the farm

@@miguelcontreras5694 depending on the configuration they retail for about 2500 € in germany. Cant say for sure about US pricing..... i guess a little cheaper (tax and stuff).

Yeah, I've noticed that German gun companies are pretty full of themselves when it comes to pricing. Not that they don't make quality products, but they all seem to have the same idea that every rifle they produce within the country should start at no less than $2k USD.

Beau Leidig I guess that is a development based on the German gun culture in general. The market is so much smaller and getting a rifle is much more complicated than in some other countries so people are more willing to spend high amounts on a piece of engineering excellence rather than getting another reliable tool. Amongst the German brands, Heym is actually one of the cheaper ones. Check out Blaser, Sauer or Mauser (all belong to the same company...) also H&K need I say more?

@@beauleidig8670 yeah, companies can built such rifles, as their customers can afford such prices. (check the Blaser prices, and Blaser is the most popular hunting rifle in Europe) Which is understandable, seeing an average European hunting course: if you've spent 3K euro on a European hunting course, you're not likely going to buy a 200 euro K98.

Fortner is cooperating with Anschütz and Heym according to his website. So for me it looks like the SR30-action is a scaled up Fortner-action, built by Heym, licensed by Fortner.

This rifle is cherry...at least to us Heym-men.

I don't think they are rare. And there's more expensive rifles out there

Exactly what I thought as well, I actually had to quickly go and check and it turns out that yes, ball bearings were a thing from the 1880s onwards. Intriguing idea.

Lets find out. TO THE TIME MACHINE!

But were good, accurate ball bearings easy to make in 1880. it was a new tech then so maybe? maybe not?

@@milamber319 Yes and no. With Ball bearings, a company makes massive numbers to an intended size, and then just filters the resulting balls by their exact size, which they can do to very exact tolerances.

And how do they manufacture so many perfectly round spheres? They have to be cast or die punched then ground and polished. The question is in 1900 is that series of machining steps on common machinery that can be done quickly and accurately in a way that is faster and cheaper than just machining a bolt. That is the tradeoff. Tolerance matching techniques is something that only really came into its own in the 1970s in mass production lines. Not to mention heat treatment tech is much better now, old bearings are often shoddy things that crack a lot. Basically im saying a ball bearing in 1900 is probably not the cheap and ubiquitous item it is today.

Did shoot the SR21 bolt action for hunting training (running boar). Very nice as well. Runs like a charm. Near perfect trigger weight.

@@TheRealColBosch , It's a spelling error that Ian didn't catch or correct.

This showed up in my list only days after ordering one. Looks quite similar to the Hex-Lock system.

Peter fortner invented it in the 80's to help his friend gain an advantage over Russian biathlon competitors - he licensed the design to Heym a while later, mine is from the 90's.

The matching recess are six ball holes or a single ring where the balls lock?

@@adrielkaua6418 Single. Built around 2001 or so. It has never failed.

they are a very odd company. their big money spinners are the double rifles, and the STR prefits the SR20 SR30 are made in small runs, that usually sell out quite quickly. I spent about a year trying to buy an SR30 prefit, in the end the first gunshop gave in and I got one by stalking an employee on Facebook. when I finally got one it was cheap, super accurate, and arrived in three weeks. madness .

@drdavid Yes, and I'm German.

And that was the first time little Timmy realized that those nasty foreigners were in his computer.

Hm well since the bolt handle is more connected to the inner moving bolt bit than the outer where it extracts, you can definitely get a bit of a runup with the bolt handle before it starts moving the bolt back, so you could probably jar a stuck case free. It wouldn't have the problem that you get when the handle is directly attached to the bolt face and you have to just pull the case free directly.

I don't know, but judging from the prices Heym charges for their rifles, my guess is that the user is expected to shoot very high quality ammunition out of this very high quality rifle and therefore never to be in the position to need extra leverage for extraction.

Advertisers and especially writers make far too much on the concept of “primary extraction,” as the subject seems to be virtually a creation of gun writers. Consider that you won’t see the subject or the theory come up in firearms literature until the 1990’s or do. This period covers the 1910-1970 period of insane work with wildcats, some grossly over pressure, but using what is considered “unsafe” actions. I’m in now way advocating unsafe firearms or firearm practices, but really!

But is there primary extraction? yes

I was under the impression that primary extraction was most useful in muddy trench warfare situations where failure to extract might have fatal consiquences?

britishmuzzleloaders? cool, i'm there.

They produce on demand AFAIK. And the SR 30 is reasonably priced in the standard version as well.

incredibly strong, there's a Finnish website where they stuff a 3006 case with a massively over proof load and fire the rifle inside a bunker using a pice of string. some scorching, the circlip is toast but the rifle is fine.

@@SuburbanBushwacker My engineering background says the balls were in compression instead of shear forces then.
