Great video Gregor. Thank you so much for this review. I'm a bit disappointed that Huben's vision changed from long distance/slug shooting to pellets. They were the leader with this new technology, and many air gunners are now looking for the slug shooting options available. FX is catching up, with a new slug barrel. I think the market is saturated with plenty of great pellet shooters within Huben's price point, and their best strategy would have been to improve the range and accuracy of slug shooting.
Very interesting. It’s going to take another 4 or 5 months to save up for whichever one (.22 or .25) I get, so by the time I have to decide I hope to see more of your testing. I’m planning to use heavy slugs at high power settings so I’d prefer .25, so I found this report disappointing. If you do put that 600mm barrel on yours, and it works, I hope it can be obtained in the USA. Even better would be a .25 factory slug barrel. Better yet would be changeable barrels like Fx, but that would no doubt bump the price.
I agree you have to shoot in no wind to get nominal precision benchmark. Huben is the only innovation in the last couple of years, other manufacturers are going in circles
Seems to me that they have regressed in their design of the.25 cal. What is the point of having all of that power if you can't use it with the bc limitations of pellets? The rest of the air gun industry is starting to progress toward bullets in order to maximize power and accuracy. This is disappointing.
Well, as I commented to AboLailaAlmohalhil, I agree with the power but I think it is a good business choice by Huben as the biggest problem with the .22 was that there were not pellets / slugs available when the gun was released.
@@gregorkamensek3923 There are plenty of slug makers on the market, but I see your point. Pellets rule the industry for now. Maybe Huben should move in the direction that FX has gone and create a platform where you can switch back and forth between bullets and pellets. It just seems a shame that Huben came out with such a powerful rifle just to waste that power on pellets in the .25 model.
Looking forward to seeing it set up for the MP slugs !! I just got my 5.52 mold for my V1 and a 6.35 mold for my Condor. Seeing you push them at 300m/s with the K1 really makes me think about getting a .25 as well 🤣🤣

Thanks. We had a lot of wind but I always find a was to go to the range, I just use something more stable in the wind. I am lucky that my better half never has a problem with me going to the range :)

Got a Huben K1 .25 today, never shot one till now. Two things i'm noticing. First, the spring clip near the magazine, which should help you inserting the pellet or slug, maybe this could damage the slug a little? It's pushing the slug against the edge of the hole while inserting the slug. Second, you definately need an earplug in the ear which is near the action, because the action itself is LOUD. Wasn't expecting that! You could also make a leather cap or something to put over the action. I'm wearing an earplug untill then.
Hi. In my experience, it should not damage the slug, a little more care is needed when inserting pellets. In my experiences, I didn't notice the action to be loud, maybe you are getting some air blown form the magazine?
@@gregorkamensek3923 I just put some JSB 25gr pellets in the magazine, and took them out. They are definately marked. Some mild scratching occurs when you put them in. The spring clip tilts them when putting them in. Not checked with slugs yet.
@@gregorkamensek3923 Tried Nielsen 37gr slug and also getting scratch marked a little on one side. Not saying this will affect accuracy but we are looking for optimum results. The spring clip is not optimal!
Great video I love it. I am a huben .22 owner shooting huben solids on the range. I find the .25 mp molds slugs ok with grouping. A firearm witch I use also is not more accurate
Ok Gregor.... Lets talk about the last 30 seconds of video where you're shooting the JSB King Heavy at 102M. You can actually see vapor trails behind the pellets. This seems strange to me as I though a vapor tail was a product of supersonic flight. But you just proved my understanding wrong. Also, looks like the Huben is more accurate with pellets than the slugs. This actually surprises me given the .25 are much more stable with the LW twist rate. Is the barrel you're shooting out of choked or un-choked? I'm assuming it's choked because of your extreme accuracy with pellets. If it is, I'm thinking you could get better results shooting your slugs if the barrel was un-choked. I also read in another video that you took a LW .22LR barrel with a 1:16 twist and had it machined to fit your Huben. How were your results with that? I've though about purchasing the LW .22 Hornet barrel with a twist of 15.4:1 and having it machined to fit my rifle so I can ensure the .22 slugs from MP-Molds are achieving max stability. Thoughts? Thanks for the great videos. I like the new haircut.
Hi. You can find the answers to first two questions / comments in the video: All K1 stock barrels are choked including this one; I intend to replace it with un-choked for slugs. Yes, I machined a .22LR barrel for K1 version 1 and it works great (I actually still use that barrel). I also tested Hornet .22 barrel. It performs reasonable well but it needs slightly bigger slugs as it is also lightly bigger than the .22LR. Both of these barrel only work well in version 1 as only version 1 (in .22) has a magazine without grooves that get in the way and also don't fit the rifling of this barrels. The .25 is without grooves and this leads me to believe that maybe the latest version of the .22 might also be without grooves. But also if it is without, the diameter of the holes is most likely too small to use those barrels if they followed in the steps of the .25 version. The twist of 1:16" is enough to stabilize the MP mold (or any other) slugs as they are all limited in length be K1's magazine. No benefits comes from the Hornet's slightly faster twist according to my tests. Thanks for the hair comment :)
@@gregorkamensek3923 Do you know if Huben plans on manufacturing an after market un-choked barrel for the .25? What good is it to have a 100 FPE air rifle and not shoot slugs with it? I'm not opposed to shooting pellets. Their accuracy within 75 yards in a good air rifle utilizing a choked barrel is hard to beat. And I LOVE the concept of the hammerless firing system used by Huben. It seems like it would eliminate 60-65% of the harmonics experienced in an air rifle where the hammer slaps the valve to release air. Just curious if you know if they plan on making an un-choked version. Also, I still love to shoot my MP-Mold slugs in .25. If you can tame the harmonics of whatever rifle you're shooting them out of, and your air rifle has a good regulator set at a high pressure, you can achieve hole in hole shots within 50 yards. I know they're designed for choked or un-choked barrels, but I've found the groups to be tighter with un-choked. They shoot laser straight out to 200 yards. Thanks for all your hard work on the design and production of those. They took my gun to a new level of power, retained energy, and long range accuracy.
@@trinitymaker5833 Hi. I doubt that they will offer an aftermarket barrel for slugs. It is quite complicated for a user to replace the barrel (including the concentric calibration). Also, I would say that Huben's week spot is that they have limited capability for accuracy testing begin form China. Also, they want to satisfy all customers with a single "configuration" and that is why the barrel is choked... I am working on putting in an un-choked poly barrel that will be thicker and longer. We will see what that does for accuracy. I can try to convince Huben to offer this as an option but I am not sure if they will be interested.
Hello Gregor, great video thank you for taking the time to make it. Where did you get the air gauge for your cylinder on the front? Can you also put the link where to get you slugs? The 25 cal. seems to be working great. Take Care, Robert
Hi. Nice to hear form you :) The gauge is made by Huben. They actually have a new model already that they showed me at IWA that is spring loaded. Try contacting distributors or Huben directly. Unfortunately, I do not sell slugs, I only designed the molds for K1: mp-molds.com/e-shop/search-result?category_ids=35
So this is difficult for me knowing it’s made in China. I’m highly against spending any money on anything from China. I’ve heard they have improved. I’d say it’s good as long as zero components are from China cause they mix their metals with crap cause they are cheap! I’d like some proof that this thing can take a beating. It looks bad ass but need more info on that subject.
Hey Gregor Kamenšek I just got into air gunning about a year ago I saw your videos on the hatsan bt65 an as u explain that gun is a beast I got one an loved it I bought a .30 cal huma regulator to make it deadly accurate I dont own a chrony but I tune an tested the hammer spring to my liking I backed it all the way out an settled on 2 full tunes it hits hard .am looking for some advice on something where can I purchase. 25 huben k1 slugs wondering what thought would feel like in my bt65 am looking to get a huben k1 some day that's my dream rifle saw ya review that rifle seems like the holy grail of all air rifle SMS. Love ya videos man so detailed u doing great bro I appriciate u good job
Tengo un Huben k1 6.35, y se rompió la pieza N°71 (magazine front cover), vivo en Argentina y no se como podría conseguirla? Tendría usted alguna idea???
Well, it is not worse, it is the same as the .22 latest version. I guess you are referring to the power and in that regard, despite the fact that I agree with you and I would also love to see it being optimized for slugs, I think that this was a good decision by Huben as the most "complaints" i received about the .22 is that people do not want to hassle with slugs, the just want it to shoot pellets well... So despite my wishes, I think majority of users will be pleased.
@@gregorkamensek3923 I totally agree with you. Huben is thinking of spreading its sales. it is business at the end. But let's remember that Huben was one step ahead in the matter of long range air-gunning. Now, major pellet makers are at the verge of producing slugs. We know that slugs do much better than pellets on longer ranges. So, why would I go for a gun that can not shot slugs!
Hello Gregor. one quick ?, does the new pressure gauge on the air tank effect the capacity/cc if looked quite big in your last video. thanks for this video.
@@badboyrick3520 Actually, I wanted to buy one to see if there is any significant difference. The fact that it cannot be externally adjusted does not bother me, but what I do not like is that it can only be adjusted up to 170 bar. I wanted to use it for the .25 K1 and for that I would need the regulated pressure of about 200 bars. I wanted to take advantage of the slightly larger plenum as when shooting slugs in .25, that would be very useful. I decided to wait for a while, but I might purchase it in the future to test it...
I shoot the Huma Rec in my FX Impact and am satisfied with it. In my K1 Cal.22 is also the original. I've made my K1 25% quieter, and increased the air by 50%. This makes the K1 about 14cm longer but has significantly more shot per filling .. I will also wait until a 200 Bar Rec is available.
I don't get it. You got great group with JSB King Heavy at over 85J and your'e saying that you recommend speed like 250m/s ( 850 fps is actually 259 m/s). Second thing... you should try NSA Slugs, i bet that some will be very accurate.
Well, there is no exact threshold real life, so I am trying to keep is simple by giving rounded numbers. Also, I use metric systems and sometimes I have a hard time calculating in my head while speaking a non native language... I tried one of the NSA slugs but as I mentioned in the video, I want to be fair to NSA as I am aware that Nick makes excellent slugs as the slugs I tried were not accurate in K1 but as mentioned, they were not designed for it. As for the velocity for accurate shooting with JSB King Heavy, I totally depends on your range. The pellets get unstable is shoot to fast with too high spin. They can be accurate at very high velocity at 50 meters but they loose stability at longer ranges giving terrible groups.
Gregor, I am looking to get the Huben K1 Gen 5 in .25 cal. I'd like to shoot slugs but am a bit confused on availability and proper sizing. I'd like to to attempt some 100-125 yd shots with slugs and am wondering which kind you recommend. I've seen NSA slugs, Hunters supply slugs, and Varmit knockers slugs all mentioned on the airgun forums. With sizes from .249 to .253. I also heard the Gen 5 has a threaded muzzle now for the .25 cal. to setup a 1/2-20 moderator. Is this an accurate statement? If slugs are more difficult to find or shoot accurately, I will just get the 0.22 cal model. Thanks for any help!
At the moment, I cannot give you any real advice with the .25 cal as I am still in process of testing. I have much more experiences with the .22 and personally, I think it will remain my favorite caliber but you might prefer the .25 because you are a hunter... As soon as I have more experiances and info on the .25, I vill have a video.
Hello Gregor, hope you are well, Stephen over at Air Velocity Sport (a US based site) has stared producing a .254 (6.4516) slug in various weights, do you believe this would fit in the K1 Mag, Regards the "US", I hope you enjoyed your time stateside, and I, and I am sure others would love to hear you thoughts on your trip, that new RTI gun looks interesting also. Be safe and good luck Thank you.
Hi. I had a blast in US :) The slug should be a perfect fit, just make sure it is under 11 mm long (0.433 inch). Huben magazine holes have diameter of 6.46 mm.
At the moment i still prefer. 22 but that might chane now that i use poly barrel on. 25... One thing is for sure, you do not gain that much more power on the. 25...
Hey man I’m really considering picking up a Huben but can’t decide between .22 and .25. Do you know if this model is the same as the newest version that’s out now?
Hi Gregor, can you please make a video about installing the new pressure gauge? Other question is what you say about barrel design in .25 cal. (more designed for pellets rather than slugs) Is that also true for K1 Gen4 in .22 cal because this barrel is also chocked.
All K1's barrels are choked, so the .22 MK4 will work well with slugs. Unchoked barrel are usually better for slugs but the .22 version still works very well with slugs. I use a custom unchoked barrel in the mk1 and it is slightly more accurately than the stock barrel, but with .25, choked barrel seems to have more problems with the slugs. I will make new videos when I have more results.
Gregor.... Buongiorno sono Francesco Italia, puoi gentilmente farmi sapere quale è la carabina più performante a tuo parere, stando al di sotto dei 2000 euro, a me piace molto la huben, però è a uscita la fx maverick, secondo te quale sarebbe la cosa giusta da prendere, e quale cal.? Grazie mille buona giornata
The NSA was not that good but as I mentioned, this is because those are not made for K1. I assume that Nick will have those available for the .25 K1 soon...:)
@gregorkamensek3923 That's funny You say to watch your videos? I kept watching them actually, and got the answer to my question, . Thank you so very much for making these videos. They're very informative and helpful. I too have a youtube channel.youtube.com/@skinnymitchairgunbrotherho7152. I won't Pester you, but if you don't mind, i'm gonna probably have to ask you several questions while i'm Going through the course of getting to know the gun and breaking it in. Thank you for answering my question.
Hi Gregor I'm going to buy my first PCP and I want to ask you what will you chose The Priest 2 or Huben K1. I want to use it for small game hunting and also some fun shooting. Thanks
These are two very different guns and I love them both. It simply depends what do you care more about: power with slugs and semi auto, or shooting pellets and customability...
@@lukaschmelar2725 would recommend getting a 300 bar scuba tank. This is a semi auto and will need to pump for about 5 minutes (or more) for what you can shoot in about 3 seconds :). I like the Huben pump but I feel that you should take this in consideration before you buy the pump...
Gregor, i have a question for you. I disassembled/reassembled my K1 maybe a dozen times, and it always went well. But this time it won't shoot anymore after reassembling. Regulated part and breech have air, and the magazine turns freely, powerwheel around 50%. Tried high and low regulator pressure, but nothing. Have you any idea where to look for?
So if I understand correct, the gun does not fire at all (nothing happens when you pull the trigger)? If so, I assume you have something blocking the sear in the rear that releases the valve... I had this situation in the past and in the end it was the spring for setting 2nd stage of trigger pull that way between the sear and the housing blocking it.
@@gregorkamensek3923 The two little springs behind the sear seem in place. I adjusted them both with allen key and the trigger responses, but still not shooting. I also removed the linkage so i could push the sear with my finger but no succes, it won't fire.
@@Harolddespui Then it is possible that there is not enough force to open the valve. This could be if the oring in the body is damaged (the oring is in the body accessible from the back side, it seals to the firing valve). If this oring is jammed in between the valve and the body, it can cause a lot of friction... But we VERY CAREFUL when you check / remove this oring, you will need to make some tool to check / remove it. DON'T DAMAGE THE ORING GROOVE as if you do, you will need to replace the whole breach... Also possible but not very likely is that something is blocking the first sear that holds the valve closed...
Depends on the version and what you shoot (pellets or slugs). For pellets, the .25 2020 + version is excellent (I do not have the .22 2020+ version yet to compare). Older versions, I would go for .22 cal, they are very good with slugs but you have to have dedicated slugs for it. I don't yet know how will the new version of the .22 perform.
I am still not 100% confident. I did seem to get slightly better results without it but that could be just a coincidence... I have juts put it back on and I intend to do some more test. The barrel is quite thin so I definitely thing that any change to barrel mounting will have some sort of effect on accuracy and also power selection is crucial...
Hello Gregor, I assume you are committing most of your free time to the RTI project and so I don't expect you have time for this however, I have just been informed by a very kind gentleman that due to covid19 the 2020 .25 K1 will not now be available until August (best case), given that My time on this earth is not getting any longer, and because I have waited soooo long already, I have two options , to move on to another gun, or buy the current version, and hope to modify, (to shot slugs, well) so. can you please do a update on the .25 K1 including what you have done to yours,to this end (slug shooting) Pretty please. many thanks.
Hello. I have been shooting my K1 .25 quite a bit actually. I have a poly unchoked barrel in it. The reason why I haven't made any video yet is because I don't get very good results with slugs. I even made a new slug but I am still not happy with the results. The poly barrel is shooting with pellets extremely well though...
@@gregorkamensek3923 Have you managed to get any H&N .25 sample Packs to try? .

@@Harolddespui Yes, actually I have. I am using LW unchoked poly. I get very good results with pellets but not so much with slugs. I intend to make a video about that...
This gun is to powerfull for the ammo!! All pellets start to destabilize at more than 320m/s.New ammo design for the future more powerfull air guns is the answer!! For now we have to shoot under 320m/s...😎Thats why l refused to purchase the K1 in .22cal in 2017.🚀
Hi there and thank you for your great videos, I really appreciate them! I just ordered one of these K1 .25 rifles to be my own. Now I would like to order some slugs at the same time. Could you measure the depth of the magazine so I would know what to order? Or do You just happen to know if Skencos Ultramag or Black Mag slugs fit to this magazine? Thanks from Finland for all your effort!
…what about pellet diameters??_ be sure to check that for your next review on accuracy. We all know @ 4% of every can is NOT perfectly pressed and some “ lead” is denser than others…jus sayin….😮😮😮😮
Pellet diameters are not as sensitive as slug diameters. In case of this gun, it is more desirable that the pellets are made out of harder alloy... There is nothing I can do about the quality of manufacturing of pellets anyway :)
6.45 is the size of the big driveband , a .25/6.35mm Lothar Walther Polygon airgun barrel has 6.45mm groove diameter and a 6.29mm bore diameter. www.lothar-walther.de/barrel-blank/airgun/polygon-profile/65/airgun-blank-6-35mm-air-polygon-od-16-mm-l-605-mm?c=50 So a 6.45 /6.46 sizer would be correct.
I m always learning, James Denny :) @Gregor : question on the Huben regulator : have you gone back to factory settings of the disks, or still trying modifications of the regulator iot reaching reduced spread ? Pls clarify. Thx. Lennert PS : Latest reports on Dutch airgun fora are claiming (newest) Huma minimal spreads of 1 to 1,5m/s (indeed for .25 Huben), radically improving accuracy (stability) beyond 100m.

Hi. You can find the answers to first two questions / comments in the video: All K1 stock barrels are choked including this one; I intend to replace it with un-choked for slugs.
Yes, I machined a .22LR barrel for K1 version 1 and it works great (I actually still use that barrel). I also tested Hornet .22 barrel. It performs reasonable well but it needs slightly bigger slugs as it is also lightly bigger than the .22LR. Both of these barrel only work well in version 1 as only version 1 (in .22) has a magazine without grooves that get in the way and also don't fit the rifling of this barrels. The .25 is without grooves and this leads me to believe that maybe the latest version of the .22 might also be without grooves. But also if it is without, the diameter of the holes is most likely too small to use those barrels if they followed in the steps of the .25 version.
The twist of 1:16" is enough to stabilize the MP mold (or any other) slugs as they are all limited in length be K1's magazine. No benefits comes from the Hornet's slightly faster twist according to my tests.
Thanks for the hair comment :)
@@gregorkamensek3923 Do you know if Huben plans on manufacturing an after market un-choked barrel for the .25? What good is it to have a 100 FPE air rifle and not shoot slugs with it? I'm not opposed to shooting pellets. Their accuracy within 75 yards in a good air rifle utilizing a choked barrel is hard to beat. And I LOVE the concept of the hammerless firing system used by Huben. It seems like it would eliminate 60-65% of the harmonics experienced in an air rifle where the hammer slaps the valve to release air. Just curious if you know if they plan on making an un-choked version.
Also, I still love to shoot my MP-Mold slugs in .25. If you can tame the harmonics of whatever rifle you're shooting them out of, and your air rifle has a good regulator set at a high pressure, you can achieve hole in hole shots within 50 yards. I know they're designed for choked or un-choked barrels, but I've found the groups to be tighter with un-choked. They shoot laser straight out to 200 yards. Thanks for all your hard work on the design and production of those. They took my gun to a new level of power, retained energy, and long range accuracy.
@@trinitymaker5833 Hi. I doubt that they will offer an aftermarket barrel for slugs. It is quite complicated for a user to replace the barrel (including the concentric calibration). Also, I would say that Huben's week spot is that they have limited capability for accuracy testing begin form China. Also, they want to satisfy all customers with a single "configuration" and that is why the barrel is choked... I am working on putting in an un-choked poly barrel that will be thicker and longer. We will see what that does for accuracy. I can try to convince Huben to offer this as an option but I am not sure if they will be interested.
Hello Gregor, great video thank you for taking the time to make it.
Where did you get the air gauge for your cylinder on the front?
Can you also put the link where to get you slugs?
The 25 cal. seems to be working great.
Take Care,
Robert
Hi. Nice to hear form you :) The gauge is made by Huben. They actually have a new model already that they showed me at IWA that is spring loaded. Try contacting distributors or Huben directly. Unfortunately, I do not sell slugs, I only designed the molds for K1:
mp-molds.com/e-shop/search-result?category_ids=35
So this is difficult for me knowing it’s made in China. I’m highly against spending any money on anything from China. I’ve heard they have improved. I’d say it’s good as long as zero components are from China cause they mix their metals with crap cause they are cheap! I’d like some proof that this thing can take a beating. It looks bad ass but need more info on that subject.
Hey Gregor Kamenšek I just got into air gunning about a year ago I saw your videos on the hatsan bt65 an as u explain that gun is a beast I got one an loved it I bought a .30 cal huma regulator to make it deadly accurate I dont own a chrony but I tune an tested the hammer spring to my liking I backed it all the way out an settled on 2 full tunes it hits hard .am looking for some advice on something where can I purchase. 25 huben k1 slugs wondering what thought would feel like in my bt65 am looking to get a huben k1 some day that's my dream rifle saw ya review that rifle seems like the holy grail of all air rifle SMS. Love ya videos man so detailed u doing great bro I appriciate u good job
Hi. You can check Huben web site to find a retailer near you...
Tengo un Huben k1 6.35, y se rompió la pieza N°71 (magazine front cover), vivo en Argentina y no se como podría conseguirla? Tendría usted alguna idea???
I can suggest you contact Francisco: www.hubenairguns.shop/
No. Entiendo porque los de huben no cambian sus cañones, estos no agrupan con slugs, porque no copian los fx
Thank you for the video.
But I must say, its a disappointment that huben has regressed.
K1 .25 should'v been better.
Well, it is not worse, it is the same as the .22 latest version. I guess you are referring to the power and in that regard, despite the fact that I agree with you and I would also love to see it being optimized for slugs, I think that this was a good decision by Huben as the most "complaints" i received about the .22 is that people do not want to hassle with slugs, the just want it to shoot pellets well... So despite my wishes, I think majority of users will be pleased.
@@gregorkamensek3923 I totally agree with you. Huben is thinking of spreading its sales. it is business at the end.
But let's remember that Huben was one step ahead in the matter of long range air-gunning. Now, major pellet makers are at the verge of producing slugs. We know that slugs do much better than pellets on longer ranges.
So, why would I go for a gun that can not shot slugs!
@@AboLailaAlmohalhil lets hope thet there will be a slug that work well in k1. 25. I will certanly work in this direction.
@@gregorkamensek3923 Hi, so far what's the best ammo for long range and accuracy for the K1?
@@archiequinez In my experiences, it is still either original Huben slugs (not the swagged version) or MP molds 2nd version 5.52 mm.
Hello Gregor.
one quick ?, does the new pressure gauge on the air tank effect the capacity/cc if looked quite big in your last video.
thanks for this video.
No. The threaded in part of the pressure gauge is about the same. No noticeable volume change...
Nice video mate keep it up
Hey ... Great video ….Do you know the Huben K1 Tuning Regulator?
A test of it would be cool.
Greetings Rick
You mean the Huma regulator for K1?
Yes....
@@badboyrick3520 Actually, I wanted to buy one to see if there is any significant difference. The fact that it cannot be externally adjusted does not bother me, but what I do not like is that it can only be adjusted up to 170 bar. I wanted to use it for the .25 K1 and for that I would need the regulated pressure of about 200 bars. I wanted to take advantage of the slightly larger plenum as when shooting slugs in .25, that would be very useful. I decided to wait for a while, but I might purchase it in the future to test it...
I shoot the Huma Rec in my FX Impact and am satisfied with it.
In my K1 Cal.22 is also the original.
I've made my K1 25% quieter, and increased the air by 50%. This makes the K1 about 14cm longer but has significantly more shot per filling ..
I will also wait until a 200 Bar Rec is available.
@@badboyrick3520 Lets hope that will have a 200 bar version...
I don't get it. You got great group with JSB King Heavy at over 85J and your'e saying that you recommend speed like 250m/s ( 850 fps is actually 259 m/s). Second thing... you should try NSA Slugs, i bet that some will be very accurate.
Well, there is no exact threshold real life, so I am trying to keep is simple by giving rounded numbers. Also, I use metric systems and sometimes I have a hard time calculating in my head while speaking a non native language... I tried one of the NSA slugs but as I mentioned in the video, I want to be fair to NSA as I am aware that Nick makes excellent slugs as the slugs I tried were not accurate in K1 but as mentioned, they were not designed for it.
As for the velocity for accurate shooting with JSB King Heavy, I totally depends on your range. The pellets get unstable is shoot to fast with too high spin. They can be accurate at very high velocity at 50 meters but they loose stability at longer ranges giving terrible groups.
Can you record some 100m or even longer range groups?
@@marcin_szper yes, when i get the slugs to work well...
Can you advise the scope brand? Thank you
Gregor, I am looking to get the Huben K1 Gen 5 in .25 cal. I'd like to shoot slugs but am a bit confused on availability and proper sizing.
I'd like to to attempt some 100-125 yd shots with slugs and am wondering which kind you recommend. I've seen NSA slugs, Hunters supply slugs, and Varmit knockers slugs all mentioned on the airgun forums. With sizes from .249 to .253.
I also heard the Gen 5 has a threaded muzzle now for the .25 cal. to setup a 1/2-20 moderator. Is this an accurate statement?
If slugs are more difficult to find or shoot accurately, I will just get the 0.22 cal model.
Thanks for any help!
At the moment, I cannot give you any real advice with the .25 cal as I am still in process of testing. I have much more experiences with the .22 and personally, I think it will remain my favorite caliber but you might prefer the .25 because you are a hunter... As soon as I have more experiances and info on the .25, I vill have a video.
Gregor, where can i buy your .254 slugs 48 grain for the 2019 Huben?
AVS in the United States sells .254 slugs but don't ship to Europe.
I am not selling slugs, I only designed them and then MP molds makes and sell molds...
Hello Gregor, hope you are well,
Stephen over at Air Velocity Sport (a US based site) has stared producing a .254 (6.4516) slug in various weights, do you believe this would fit in the K1 Mag,
Regards the "US", I hope you enjoyed your time stateside, and I, and I am sure others would love to hear you thoughts on your trip, that new RTI gun looks interesting also.
Be safe and good luck
Thank you.
Hi. I had a blast in US :)
The slug should be a perfect fit, just make sure it is under 11 mm long (0.433 inch). Huben magazine holes have diameter of 6.46 mm.
Thought they only made this in 22 cal? Which is a better caliber I'm gonna say the 22 got more punch yeah?
At the moment i still prefer. 22 but that might chane now that i use poly barrel on. 25... One thing is for sure, you do not gain that much more power on the. 25...
Hey man I’m really considering picking up a Huben but can’t decide between .22 and .25. Do you know if this model is the same as the newest version that’s out now?
The new model is a bit different. Huben told me that I will get one for test in about one month and I will make a video with it.
Quanto fica uma k1 dessa
Hi Gregor, can you please make a video about installing the new pressure gauge?
Other question is what you say about barrel design in .25 cal. (more designed for pellets rather than slugs) Is that also true for K1 Gen4 in .22 cal because this barrel is also chocked.
All K1's barrels are choked, so the .22 MK4 will work well with slugs. Unchoked barrel are usually better for slugs but the .22 version still works very well with slugs. I use a custom unchoked barrel in the mk1 and it is slightly more accurately than the stock barrel, but with .25, choked barrel seems to have more problems with the slugs. I will make new videos when I have more results.
Return the Huben and get a LCS Air Arms SK-19. Your slugs will have no issue.
Gregor.... Buongiorno sono Francesco Italia, puoi gentilmente farmi sapere quale è la carabina più performante a tuo parere, stando al di sotto dei 2000 euro, a me piace molto la huben, però è a uscita la fx maverick, secondo te quale sarebbe la cosa giusta da prendere, e quale cal.? Grazie mille buona giornata
It completely depends on what is "best performance" for you. Is it accuracy? Power? Semi-auto?...
I didn't see a nsa slug group there. Them jsb cracking group.
The NSA was not that good but as I mentioned, this is because those are not made for K1. I assume that Nick will have those available for the .25 K1 soon...:)

Maybe the pressure gauge is not correct. Try to increase the pressure even more, lets say up to 22 mpa...
Hi Gregor I'm going to buy my first PCP and I want to ask you what will you chose The Priest 2 or Huben K1. I want to use it for small game hunting and also some fun shooting. Thanks
These are two very different guns and I love them both. It simply depends what do you care more about: power with slugs and semi auto, or shooting pellets and customability...
Huben K1 .25 is my new first PCP. Thanks for your help. Now I want Huben pump but I can't find any.
@@lukaschmelar2725 would recommend getting a 300 bar scuba tank. This is a semi auto and will need to pump for about 5 minutes (or more) for what you can shoot in about 3 seconds :). I like the Huben pump but I feel that you should take this in consideration before you buy the pump...
Gregor, i have a question for you. I disassembled/reassembled my K1 maybe a dozen times, and it always went well.
But this time it won't shoot anymore after reassembling. Regulated part and breech have air, and the magazine turns freely, powerwheel around 50%. Tried high and low regulator pressure, but nothing.
Have you any idea where to look for?
So if I understand correct, the gun does not fire at all (nothing happens when you pull the trigger)? If so, I assume you have something blocking the sear in the rear that releases the valve... I had this situation in the past and in the end it was the spring for setting 2nd stage of trigger pull that way between the sear and the housing blocking it.
@@gregorkamensek3923 The two little springs behind the sear seem in place. I adjusted them both with allen key and the trigger responses, but still not shooting.
I also removed the linkage so i could push the sear with my finger but no succes, it won't fire.
@@gregorkamensek3923 It's shooting again. Removed the small cover and poked against the striker hammer. Cover back on and go.
@@Harolddespui Then it is possible that there is not enough force to open the valve. This could be if the oring in the body is damaged (the oring is in the body accessible from the back side, it seals to the firing valve). If this oring is jammed in between the valve and the body, it can cause a lot of friction... But we VERY CAREFUL when you check / remove this oring, you will need to make some tool to check / remove it. DON'T DAMAGE THE ORING GROOVE as if you do, you will need to replace the whole breach...
Also possible but not very likely is that something is blocking the first sear that holds the valve closed...
@@gregorkamensek3923 YES, Correct
Friend, which caliber was more accurate for you, the .22 or the .25?
Depends on the version and what you shoot (pellets or slugs). For pellets, the .25 2020 + version is excellent (I do not have the .22 2020+ version yet to compare). Older versions, I would go for .22 cal, they are very good with slugs but you have to have dedicated slugs for it. I don't yet know how will the new version of the .22 perform.
@@gregorkamensek3923 ok friend!
Hello Gregor. (another ) quick ?, The front clamp. could removing it have affected the harmonics.
thanks, and sorry to torture you.
I am still not 100% confident. I did seem to get slightly better results without it but that could be just a coincidence... I have juts put it back on and I intend to do some more test. The barrel is quite thin so I definitely thing that any change to barrel mounting will have some sort of effect on accuracy and also power selection is crucial...
Hello Gregor, I assume you are committing most of your free time to the RTI project and so I don't expect you have time for this however,
I have just been informed by a very kind gentleman that due to covid19 the 2020 .25 K1 will not now be available until August (best case), given that My time on this earth is not getting any longer, and because I have waited soooo long already, I have two options , to move on to another gun, or buy the current version, and hope to modify, (to shot slugs, well) so.
can you please do a update on the .25 K1 including what you have done to yours,to this end (slug shooting) Pretty please.
many thanks.
Hello again Gregor, please ignore my above begging Email, it would belittle us both where you to respond,
good luck.
Hello. I have been shooting my K1 .25 quite a bit actually. I have a poly unchoked barrel in it. The reason why I haven't made any video yet is because I don't get very good results with slugs. I even made a new slug but I am still not happy with the results. The poly barrel is shooting with pellets extremely well though...
@@gregorkamensek3923 Have you managed to get any H&N .25 sample Packs to try? .

@@henrymoreland8719 Thank you and a big thumb!
…what about pellet diameters??_ be sure to check that for your next review on accuracy. We all know @ 4% of every can is NOT perfectly pressed and some “ lead” is denser than others…jus sayin….😮😮😮😮
Pellet diameters are not as sensitive as slug diameters. In case of this gun, it is more desirable that the pellets are made out of harder alloy... There is nothing I can do about the quality of manufacturing of pellets anyway :)
sizer 6.45mm... did you mean 6.35 ?.... 6.45mm seem to large
6.45 is the size of the big driveband , a .25/6.35mm Lothar Walther Polygon airgun barrel has 6.45mm groove diameter and a 6.29mm bore diameter.
