I’m 50 and have been interested in firearms for decades. Never heard of this, thank you.

Sir, Your quiet, thoughtful, and measured approach to your subject is so very much appreciated. Thank you for an excellent video!

This channel is living proof that the presenter can have an immense influence on his audience. It’s not a coincidence that this is one of the most civilised comment sections on KZfaq. It kinda feels like I’m in class with that one eloquent, soft spoken teacher who nevertheless managed to captivate the attention of everyone and made class fly by too fast.

I could not have imagined an action like the Sembrio, incredible! Thank you!

Glad to see a video on the Semprio!

My friend who isn't a big gun nut got invited to go shooting with his godfather today. Afterwards he told me about a pump action rifle he tried out. I was like alright those are plentiful. He described it even more and showed me a picture. I have never seen a factory made reverse pump magazine fed gun before. The closest thing to something like this i've ever seen is the Idahoan Show's homemade shotgun. I instantly went through Forgotten Weapons's channel to try and find something about it as he didn't know the gun's name. Then I ended up here. Truly a magnificent piece of engineering. Might have to tag along for the next time he goes to the range..

Don't know what to say, I may never lay my hands on the Semprio, but at least now I know it exist. Thanks for the video!!! Learned~!

Legend.I just knew you would do a kreighoff review. Thanks.

Outstanding presentation and coverage of those rifles. Very nice designs. Did not know they existed. Many thinks for bringing that to our attention. :-)

I don't know how you ever got to a position to be able to amass a collection to that vast variety of fantastic firearms you have but I'm glad you did. I've watched you for a while and can say I thoroughly enjoy your videos. I really enjoy you unassuming approach to explaining your collection and the logical step by step break down of your thoughts and perspective on how these firearms are developed. Thanks for a glimps into your amazing and obviously loved collection. I can easily say I have seen firearms on your reviews I would never have seen had I not clicked on your first video I watched. Thanks again.

Great video. Well paced and informative.

another great video by you ! Keep up the good work you do . Greetings from norway ;)

Just great! Thanks. Love the history mixed with your enthusiasm.

Thank you for the great video. I Really enjoy your in depth way of describing these really awesomely designed firearms. Thanks again.

Whats Amazing is You Give a very detailed view of 4 rifles, each rifle has it's quirks and downsides.You talk us into all 4 rifles, and Bow out Gracefully ! Nice Job

Great to see someones making a video on the semprio! Currently have a HEYM SR21 as my main rifle and thinking about switching to a semprio. Your Video really helps! Great Channel!

Great review!!!

This video brings new meaning to the phrase " In Depth review". Excelleent.

Great video. Learned a bunch. Good job.

I am very impressed with your reviews! You have great knowledge of firearm design and history! Thank you for spending your time sharing such magnificent pieces of firearm engineering. Look forward to binge watching all of your vids.

Super video. I was unable to see how the locking lugs engage. Your gun videos are the best ever!

It is certainly interesting for us all to see you get so excited about such unique mechanisms this way. I completely sympathize with you in that regard. Thank you for taking the time to review these items often so unfamiliar to the traditional American gun owner.

Australian viewer here , can have most of everything shown in this video , I personally took a look at a browning Maral rifle in .300wn at a local dealer . Keep up the good stuff .

Treasures. You have actual real life treasures. I am in awe of your taste in rifles.

You have one of the most interesting and classic private collections.

exceptional video!

I had just watch the Krieghoff video the other day and was hoping to find an independent review of it. Awesome job Sir!

Great info on guns that I didn't know I was interested in or even knew existed. Pure learning experience.

Great video and the various styles of actions, and differences between with the explanations of them are great.

Fascinating. The sights moving on the Semprio may give an advantage to the Remington. Nonetheless, unique and a total surprise. It's really interesting to see the vastly different design philosophies between Europe and the US. As always, thank you for showing us. These guns (european) price wise are beyond most of us.

I have my grandfathers 760 Game Master. Rugged, reliable and fast. I like those examples. The Merkel Helix with muscle memory is obviously very fast. I can see the physics of speed in return to battery of the Krieghoff Semorio. That’s wonderful.

Wow sir!! What an incredible video!! Thank you so much!! Great video!!

Very interesting, actions I have never been acquainted with..!

Excellent class.

Thank you for this very interesting video. :)

Thank you for your vids

Liking this channel!

EXTREMELY well done 🌎

Love your vids! Your persona in front of the camera is exactly what a gun reviewer should be. You don't bounce around pointing your subjects at everything and going all giddy with excitement of the gung ho mindset. It seems that you see your job as being the hands that act as those of your viewer while you explain the subject matter at hand. My firearms instructor shooting instructor as well as hunting and all things outdoors instructor father would love your channel were he still with us.

You are very noble Man! Thank you and God Bless!

Very interesting. Always like seeing different action styles. I don't think I will ever see one in person however. You did not mention the caliber of the rifle. My first, and only straight pull rifle was a Schmidt-Rubin. I still marvel at the machining required to produce it. Keep up the excellent reviews as this is the only place to see these fine rifles demonstrated.

I have been watching your videos almost religiously over the past few months. It`s great that a knowledgeable gun collector like yourself open a youtube channel, with a hands on experience of a lot of rifles and a substantial amount of fire arms to compare them to. I think the in-line action of the Krieghoff rifle is a great idea and of course, is an outstanding engineering accomplishment. I believe JMB had a patent for something similar. The only drawback with such a design would be that you would lose your scope picture during the reloading operation. I believe it would be more satisfying if the scope was connected to the stock-part of the rifle. Please keep the great videos coming! Best Regards, Magnus

I kept marveling at the engineering of the Krieghoff and it's farsightedness. However I keep hating myself for liking the "inferior" more down to earth Merkel. I just love the blue and walnut the straight pull that's lightning fast and the extruded magazine might seem unsightly to some but not me, I already have those in CZ's micro bolts. BTW the heavy sotck on the Krieghoff you spoke of kinda reminded me of yet another rifle I wish I never sold, the H&K SLB2000 NIB too I don't see those around very often.

You make very interesting and entertaining videos !!

Nice review but I’d like to make some comments. First of all, when something new comes out there will allways be people who oppose the change. This is exactly what happened when the Blaser R93 came out. It was so different that it was a shock to a lot of traditionalists. The when a few R93’s blew up after being fed some very very hot loaded handloads that by far exeeded safety specs they had found something to rant about. But there has never been a case of a Blaser blowing up with factory loads or handloads that were not overloaded. No R8 that I ever heard of blew up. Second, to my opinion it is not only about how fast you can cycle a round but more about how fast you can get the next round on target. With the R8 and the Helix the movement is contained between the shoulder and the left hand so that only the middle of the rifle is moving. With the Semprio the front end of the rifle is swinging around. Also the scope is moving back and forth so a lot more mass has be put in motion, a lot more energy has to be put in. That costs more time to get the rifle back in shooting position and get it steady again.

Very good Video i use the Semprio since 3 years and its a perfect accurate gun best regards from germany very good review

I like the way the Sembrio barrel can be cleaned from the rear.

Very interesting vid. Did not know it existed. Very great engineering .

Thank you very much for creating this video and comparing these rifles. The Semprio is amazing. I've shot a Rem 760 and pump shotgun. The design of the Semprio is better thinking of operation.

Blaser R8 is popular here in Norway, easy to travel with and use. Semprio is rather unknown here.

I have taken many white tail deer with my model 760, .308 caliber carbine. Handles like a dream and it alway comes right to your line of sight when you bring it to your shoulder.

Just discovered your channel, quite enjoy it! A bit difficult to find such informed discussion of higher end hunting rifles.

So interesting!

Wow great review. Hope you can do the Sauer 101 Forest. Thank you for posting.

We Are Greatly Served by your thorough, and most civilized, presentations! This Semprio design is exceptionally intriguing. I will certainly explore it further. To me, you appear to be captivated by the mechanical system that any given gun manifests. I myself, would be a charter member of that society. A simple example of genius design for a hunting rifle, (or shotgun) is the double barrel by George Hoenig, a virtuoso gun maker.

That is the most awesome takedown rifle I’ve ever seen! The scope mounts where it should and stays with the barrel. I know that wasn’t the point of your wonderful video but I have a predilection for takedown rifles and love this one.

The Kreighoff Semprio reminded me of the Czech SS41 from WW2. All very interesting designs - I'm particularly interested because of a project I'm working on. Great channel, great videos - thank you!

Hello Thanks to your well made video in 2019 i purchased a Semprio.It is extraordinary, extremely fast.Mine is in 7x64, more than enough for driven hunt;Equipped with a Kahles K16i just magic.I had some worries about the scope coming back toward my eyes, absolutely no problem I noticed an interesting feature, never touched before i thing.Has the slam fire .If you keep the trigger pulled, it will fire every time you close the gun.Kinda useless, but fun feature.

Great video from you and great gun you show to the youtiuber..

A masterpiece. Outstanding quality compared to the plastic R8, in my opinion. As fast as a semi auto, as accurate as a bolt action. Only negative thing is it’s weight, heavier than most comparable rifles.

I find this chanell like Forgotten weapons, only more interesting.

great review, as always. i have an idea that any of these seemingly excellent products are hard to find and afford, but for a one hobby person, maybe a person could pursue this dream with eventual success. i still have a soft spot for a browing safari II with the old styling and the iron sights, but i really don't need anymore....

The Semprio is a very unique firearm but I believe I'd prefer the Helix. Then the Semprio 2nd. I already own a couple 760's handed down to me from my father that after starting hunting at age12 with a Winchester in 32 Special at the age of 14 my father bought me the 760. Thank you.

Another fascinating video. Thank you. BTW, these rifles can be owned in the UK. However, semis are limited to .22LR. Pump rifles are just not popular but the Blaser is quite popular.

Not as novel as one might imagine. The Czech ss41 anti tank bull pup repetierbüchse is the origin of the semprio. The waffen ss used these bullpups during the second world war most unsuccessfully in the calibre 7.92x 94mm.

The 760 action is a familiar one for me. The Sempio is Similar to the Browning pump rifle that wasn't a hit in North America. Nice Review!

Fantastic. You have even taken the initiative and the extra dollars to purchase 3 rifles which epitomize engineering precision, quality parts, accuracy and art some Although, some designs can be over-engineered. I have always liked the R99 and R8..removable bolt heads and quick detachtachable barrels which allow the shooter to select any cartridge for any game.

Great Video. But as a user of all of these German guns I have to add some facts that were not mentioned. First of all, the Blaser R8 is the best established hunting rifle in Germany. It was meanwhile tested by a governmental institution up to 18.000 bar pressure on the locking mechanism and never failed. This is because they changed the design of the locking mechanism - they added an additional plate under the claws that hold it into the barrel. Now it's nearly impossible that it will come out of the barrel. All of these guns can be easily disassembled by the user and barrels can be changed within seconds. You can adapt these rifles to everything you hunt, so you only need one rifle! All of them have manual cocking mechanisms and due to are outstanding safe, what is very high rated in Europe, because you don't need to train that much to reach a good safety level. They have excellent triggers. The one of the R8 can be switched between 650 gr. and 150 gr. by turning a knot on the detachable trigger/ magazine and the way to break the shoot is 1.5 mm. Despite that it will not release the trigger when it was dropped when cocked. The scopes on the R8 and the Semprio are mounted on the barrel and you can exchange them together with the barrel. So you can have several barrel - scopes combinations and you can change them within seconds without adapting the rifle by shooting. The fore and the back shaft can be exchanged by opening some screws - so you can change between a standard shaft and thumbhole one etc. The Merkel Helix only weighs 2.8 kg - you can add heavy barrels, suppressors etc. and you still have a light weight gun. Additionally it has an integrated Picantinny rail on the top for mounting scopes, which gives you the whole range of cheap scope mounts. Of course all of these rifles are produced with high precision, superior to all AR15 clones. Best Regards from Germany!

I'm not sure whether the 'lock-open' feature is something required by German law. But mostly, these things are about 'safety etiquette'. Whenever you're at a hunt, your fellow hunters want to see from a distance (as far as the next post in a driven hunt) whether or not your gun is unloaded. The bolt-actions, the Blasers or even the break actions, are easy: you can clearly see from a distance that it's unloaded. Hence semi-autos are often not allowed (the game master can tell you to go home and not come back, if he/she sees you sporting one). The Krieghoff solved that problem by simply having the gun slided open. Sliding 'half-open' also prevents getting dirt and leaves in your gun.

👽The same thing holds true for the old Winchester model 12 16 gauge pump.. it sort of pumps itself. And I like this guy.

I'll stick with the Remington 14's short action. It's a short, tough woods companion totally at home in brush.

I loved the first Semprio I held but after sales service for Blaser over here is second to none. Plus there are plenty of spare barrels floating around on the second hand market. If you add a scope to the barrel and big scope that is a lot of reciprocating mass to move forward. Probably not an issue with a small red dot for driven hunts.

The Semprio is gorgeous.

I greatly appreciate your videos. I am not elk hunting this year, but for next year I plan to replace my bolt action with a straight pull. Your videos are the start of my research in that regard. While I am often eager to adopt new technology, a couple of cons on this design occur to me. You already mentioned the large reciprocating mass, and that is without the additional mass of a scope. But also consider the additional trouble of having to lift the forearm from a rest, such as a ground blind, for the follow-up shot. Also, if if the scope base alone cost over $500 in 2018, then it seems that I could hardly justify the supposed price of this rife. So my initial candidates at this early stage are the Merkel Helix, the Browning Maral, and the Savage Impulse. The latter would win on price only. I have suffered baffling quality problems with Savage. And I have had that nearly identical stock on a Savage bolt action, and it felt cheap.

Nice video, you should test the new straight pull rifle it`s called Steel action HS. The system is like in biathlon, really quick to handle.

Your a wealthy man arent you. An thats not a bad thing as long as you possess things an not let them possess you. You probably have the best gun collection in the world. An that a good inspiration to us all. An i like your attitude. Good job sir. May you continue to prosper.

Moss berg is my choice pump It's affordable popular and parts are easy to obtain . Also several different guages and models to choose from One model even can take up to a twenty rd magazine . Very simple to take apart to clean or replace parts

Nice video and you have the best german-made rifles collection, Hope to see Heym express bolt action rifle

Great video as usual!

Thanks for opinion! Semprio is awesome firearm. Very unique. But if you really need speed shooting while hunting on dangerous animals like grizzly bear, I'd say that semi-auto (like Browning BAR) is more wise choise. And if you need to make distant precision shot, a common bolt action rifle (like Tikka T3x or Rem 700) would be more accurate than this piece of art. Anyway, these are my reasons why I still don't have a Semprio. But I really like how it looks, and how it goes. And that pump sound it produces between shots is awesome.

I love the R8. Especially the suppressed model. My issue with the R8 is the magazine being a part of the trigger assembly.

18:24 Why not? Like your videos after a long day on the couch, sometimes sleeping at the end. I don't say by any means they are boring, quite the opposite, but I like your calm voice, it's relaxing IMO.

at first, the "backwards" motion seemed bizarre, but it actually does make sense that the motion pulls it back against your shoulder instead of pushing it away like the traditional motion

Krieghoff Seprio 👌🏼

Hi, thanks for sharing your wonderful collection! What do you think of the Finnish Lynx rifle? It's got an interesting straight pull action. Cheers!

Kiitos 🙏

Complimenti per la tinta.

All great designs but the Semprio takes the cake.

One way to test primary extraction is to slightly deform a cartridge case with needle nose pliers, chamber the case, and then (try to) extract it and feel the force needed. Examining the recesses the bolt locks into can give an idea e.g. caming surfaces. It would be interesting to see what the colletts lock into but that would be difficult to see in person let alone to film. Best regards--Conrad

Seems more novelty than practical for a sporting rifle. Looks like a solution for a problem that doesn’t exist.

i am very interesed in straight pull bolt action mechanisms, but semprio is very singular too... thanks

Like most things Germ.....this is a great idea that could probably be vastly simplified . Germs have a passion for intricate design. I'd love to see the no nonsense Russian take on this action. The idea that the action itself is the takedown feature kinda kills two birds one stone . Though ....it is hard to imagine a more well designed firearm than the Savage 99 takedown combo with a optional 410 barrel. Far as manual operated rifles , there isn't much to improve there...

very interesting. difficult to get in the US which means it will be impossible to get in Canada. With a small firearms market, there might not be enough demand to justify importing a Krieghoff in to Canada but if they did, I would be in the market for one. Another informative video.

I was fascinated by your experimentation with that stainless steel unrifled smooth bore hyper velocity “rifle” and analysis of what happens to the propelled bullet. The different action designs are also very interesting. Keep researching. I love to watch your blog. Are you from the U.K. ? Stay in touch.

Nice video. My main criticism to all pump or lever action rifles are that they are awkward to operate prone, or while shooting from an improvised rest like a branch or a shooting stick.

Hi sir it's the guy form downunder I just saw this awesome review and really got interested in the smpiro and just noticed that in the review that you missing the Rols Do you recommend the Smpiro over the R8 Thanks and sorry for long write

This shotguns make my breda brescia 12ga look like a keltec

I have been re-viewing your videos, I love the science of comparing different actions and was thinking about the complex Semprio action (which is really impressive), but then I was thinking about the rolling block action with its extreme simplicity, which I value as a important characteristic of rifle design. In researching the rolling block, I could not get a sense of how strong that action really is. Part of the problem as I see it, is that it was developed in the black powder metallic cartridge days and was produced in great numbers through the transitional period to smokeless powders and is even made in beautiful reproductions (Italian) today. So we have a situation, where we have functional rolling blocks that are very old (a testament to the durability of the design) and on the other hand, I have read about failures and action strength concerns. I am wondering if this criticism is justified in a modern made (made for modern smokeless powders) rolling block or not. The question becomes, is a modern manufactured rolling block a strong action? Opinions vary. Either way, I think the rolling block deserves some praise for it role it played in history. Many thanks for the wonderful videos!

Krieghoff Semprio 30-06 here in Canada as of 2020 will run you about $5200.00 and a trip to the hospital if your wife finds out. The Merkel Helix about $4300.00.

Amazing design. I wonder if it would be disorienting with a scope mounted as the scope would follow the action forward and backward.
