- What will you get from changing your barrel from a 600 mm to a 700 mm??
In this video I will test the velocity in both barrels with the gun on the same settings.
At the end of the video I will test the 700 mm barrel for accuracy on 100 m/109Yd.
My reg is at 100 bar.
Hammer at 2,6 (micro adjuster scale)
Front valve: 3
I hope that you will enjoy
Best regards

Thank you for your video. This has helped make up my mind to buy an FX impact and also to get a longer barrel. Great work, thank you
You are welcome 🙂
Im glad that I could help.
I hope that you will be happy with the Impact 😎
Great group and video, Peter!! This type of testing is extremely useful for us, so we can see the improvements before we spend our money on a new barrel. I live in the US, and dearly wish we would adopt the metric system. Much more logical. Again, great job!!
Thanks Tom 🙂
One of my goals is to do that exactly - to answer the questions that I have been asking myself.
And testing is not only a persuit of positive answers 🙂
I have a test commin up about weighing the slugs and the effect on the accuracy. Pretty excited about that one 😃
Thank you for this video, I thought about ordering FX M3 600mm barrels in .177 or 700mm barrels, so they had a difference in muzzle velocity of about 20 m and convinced that 600mm will suffice. The accuracy at 100m is almost the same. Thank you very much👍
Really appreciate your videos and knowledge!! Thank you !!! Love every video!!👍🏻
Thank you Robert 🙂
I really appreciate it 🤗
Amazing group, never thought the .177 would be this accurate. I’ve seen few people shooting the jsb ko with the 500 mm and 600 mm liners and they don’t get this results even at 40 meters !! Well done 👍
Thanks mate 🙂
I really believe that there is a possibility with the 700 mm 🙂
Great video please keep up the good work 👍
Wow, I had no idea there were so many factors which can alter the POI, I wrongly assumed it would only be something like an external appendage, which could wobble. My reason for asking was, I have seen someone use a tiny tripod with the chronograph mounted on it, positioned where you had yours, so totally isolating the rifle & projectile from any contributing factors, or so I thought up until now.
Your comments have led me to realise I now need a Torque Driver for all the fasteners. Thank you very much for the information, keep up the good work
Yay! Thank you for this; amazing group, Peter!!
Thanks Felix 🤗
@@VikingAirgunner Peter, I got my tune; 1" groups today at 101 yards! I thought I was missing the target because they were so close :) Thanks again for blazing the trail with .177 slugs. Could not get chrony on it due to the bad light conditions :(
Amazing group. Congratulations.
Thank you Bruno 😀🤗
Hi mate, thanks for the mention.....Another good video and great shooting
You are welcome my friend 🙂
Excellent video clean and simple
Thanks Andy 🙂
Have a nice weekend
👏👏👏👏amazing group!!!
Sub moa with a. 177 group, wow, nicely done. 👏
Good video. I think you should adjust your Micro wheel again and Valve return spring also have to adjust for more consistent.
The barrel length does not change accuracy, only changes velocity. You can go for a higher velocities to shoot further, or tune down the gun shoot the same velocity you had with the 600mm in order to get a higher shot count. The gun needs to be tuned in order to get a smaller SD and better grouping.
Well that is not entirely accurate since a much shorter barrel is impacted more with gun movement. But if you could fire without moving the gun at all (like in a vice, you are correct)
First of all thanks a lot for the great videos (not only this one) Peter!
Notice how your group is spread vertically more than horizontally. That means the spread in your muzzle velocity is affecting the accuracy! But honestly it's a bit strange, you should be able to get velocity spread under 5 fps from FX Impact with no big effort. Remember that every barrel needs to be break in. You need to shoot 100-200 times from the barrel to smooth out imperfections in the barrel. Also don't change ammo too much. Especially different hardness/composition of the lead they are made from have an effect and the barrel needs another 3-10 shots to "get used to" the new ammo.
If the velocity spread doesn't improve in next 100+ shots, you should try to play with the regulator pressure and hammer preload. Just try to increase the reg pressure and set hammer so it opens the valve for shorter period of time (should improve accuracy of slugs even more). If that doesn't help with the velocity spread, try the opposite.
Don't clean your FX barrels unless the groups get worse over time!
Have a great time shooting and be safe!
Hi Jan
Thank you so much for taking the time to share your experiences 🙂 They all make perfectly good sense!
I have had difficoulties getting my spread down and after installing the Sekhmet it was clear that the reg was the problem being around 15 seconds to fill completely. So for the last two months my rifle has been to service. It should be on the way back to me with a new reg and a new liner (dont know why with the liner🤔)
Your advise with the higher reg makes sense. Gerhard recently said the same, but since he is using the original transfer port he has to go high.
When I just recieved the gun the spread was almost non exciting, so I know that it is possible, so when I get it back I hope that it will behave again 😃
Thanks again for your input!
Best regards
Peter P 🙂
Looks good mate! I wonder if you might benefit from indexing your liner and then using the harmonic tuner. It looks like your trailing off from upper left to bottom right, so maybe if you index your barrel just a touch, you might get those in a vertical line and then be able to clean it up further with the tuner. I have tried the KOs with my 600mm on my Crown, and they did not seem to like being shot at higher velocities. It was like a shotgun when I was shooting at 950-1000 fps, but then when I got into the 800s it started to get better. It was not great, but better. I need to do more work with them and I may be able to get them to group well.
Hi Pat
I never thought about indexing the liner. Thanks for sharing that idea mate 🙂
I want to get the tune as good as I can before using the barrel tuner. I have a cf barrel housing commin shortly, so there are still a few projects before, but it is comming 🙂
I think that there are many sweetspots at different velocities. Recently got a Wildcat and I had that shooting well at 760 fps and again at 850fps.
I wish I was better at tuning, but it is a proces - so thanks again for your input 🤗🤗
Very impressive
Thanks Jim 🙂
Great video in such a beautiful place. A little suprised at the small increase in speed with the longer barrel. But as you say it's really all about accuracy. Looks like the M3 with the 700mm barrel using KnockOuts is a great combination. Keep sharing and Thanks!
I actually expected a greater difference in velocity between the two barrels since the diference between the 500 and the 600 mm was to big!
Feeling very lucky to have a place like that to shoot 😎
Best regards
Peter P
Nice test, great shot, I have the reg at 115 , 700mm barrel ,around 970 980 fps with 5.5 cal jab exactheavy and Hades sub M o a at 100m and I cut a cigarette at this distance , have fun
That is seriously good shooting mate 😎
Wish we didnt have the laws regarding caliber size in Denmark 😃
Nice review. I wish i have one😭😭
That'll do nicely. There might be even more to come with a tweak of the tuner. I have some pro hunter 13gr slugs to test in the spring. If they don't suite your welcome to them. atb neil
Thank you Neil 🙂
👏👏👏👏Hi friend, nice comparison and it prevents me from doing it lol 😂; I just tried at 45m group with the 700mm of 1cm by 1cm it's pretty I think and I only had one support before 😉
Thats a good start buddy 😎
Nice shooting.
Surprised at small gain in speed.
Might need more shots through new barrel to lead it in.
Something else is not the same.
Larger calibers show significant increases every 100mm.
I'm waiting for the FX MK4 with a 800mm barrel.
Cheers from sunny Florida 🌞 ☀️ 😎
Yeah lets see where the length of the barrels ends 😃
Im really happy with the 700 mm. The 600 mm is on my Wildcat now 😃
I think that the increase would be bigger if the reg had been higher. When we tested the 500 vs the 600 in the Mk2 the gun was tuned for the 500.
Here it was the other way around. But I still dont think that the gain would have been as significant.
The sun and the good weather is still a couple of months away here.
Kinda excited to see what higher temp will do for the accuracy 🤓 It usually helps - maybe I will be shooting hole in hole by June 😃😎😂
Best regards mate 😎
Great Peter and very nice group although the spread seems doesn't mean nothing...
Thank you my friend 🙂
Im kinda excited to see what a tighter spread will do to the accuracy 😀 At the moment I really cant imagine my self shooting a better group 😂
Is the second reg taking longer to fill this could be the cause as it should be a second to fill , the longer it takes the bigger the spread of speed so I think the second reg is not working properly
Did not hear that air was topped off with each barrel. So Jodie’s one make a comparison?
Awesome. The longer barrel usually shines at greater distances. I’m trying to get my M3 22cal to shoot slugs and having difficulty. Going to try the carbon barrel liner or the heavy slug barrel. Thanks for the update.
Anything that can make it more stiff and with less vibrations 🙂
Im a big fan of the barrel sleeves 🤗
Longer barrel benefits only when You can hold Your gun steady as hell. Longer barrel = more barrel dwell time. If You are only shooting from bench, longer barrel is good, but when shooting off the hand, then it is bad.
@@paavokaleva I agree. I could not imagine holding this gun off hand - or it would be kinda fun to do a video where I tried 😂
@@VikingAirgunner It would be nice entertainment to see accuracy at 50m shooting off hand. I bet You are familiar with AEAC Vlog YT channel and Airgun Exploration & Advancement Channel. Then You probably know that max fps doesn't mean max accuracy. That waste air behind projectile leaving muzzle.
@@paavokaleva And thats also why I say that Im not nesecarely interested in higher velocity - but more like the right velocity 🙂
I will go and check out the channels that you mention.
Thanks for sharing mate 🤗
Great video ,👍
Any chance trying the 16 beast in z 700 liner ?
Thanks man 🙂
I might do that some time 🙂
Money , money , money ! FX has marketed well and makes a good profit on these conversions . I’ve been there and done that .
I love shooting , not experimenting and clearing out my bank account with moderate to no results .
I’ve also done it in archery as well spending thousands of dollars for just 20-30 FPS .
What we all should be doing is enjoying our sport . We won’t because we are never satisfied . 😁
Best 👍👍👍
Great group !! Is the vertical poi spread not resulting from the significant velocity spread? At 100m, I assume that a difference of 30 fps translates to vertical poi shift. If your average velocity is not to close to the plateau velocity for your reg pressure, maybe you can slightly increase your HST and see if that gives you a lower ES. In terms of ES, the sweet spot is usually just a few fps below the plateau velocity. But I'm sure you know that. Just let us know how you address this issue. As far as I remember, in his Power Tune video, M Dubber talks about longer barrels. You might find interesting clues in there.
Hi Steph
It makes really good sense with the vertical shift ☝️
So far I have been focusing on the valve and I still believe that I can improve the tune by some fine adjusting. I have seen some changes in ES so not all done here.
And with the ES being so much better in the 600 mm it could mean that I have turned the valve to far in for the 700 mm? 🤔 Valve closing to soon.
I actually think that the M3 is capeable of doing an even better group - and thinking about my bench (a camping tsble) it would help to get a table that is rock solid 🤓
@@VikingAirgunner Yep, a sturdy table would be a good investment 😀 Build it yourself, you will exactly get the quality you want. I have started building mine to shoot at 50m in my backyard. Good luck with your tune. No doubt you'll figure out how to get your velocity spread fine.
I really enjoy your videos & that's amazing accuracy ! Couple of questions (on the 700mm barrel) ; what is the regulator pressure & are you using the harmonic barrel tuner ? (I'm using NSA 177 12.5gr at 970fps with regulator 85 bar - and the accuracy is poor so far).
Since my spread is so bad I dont really recommend my settings, but I have the reg at 100, micro adjuster at 2,5 and valve at 3 🙂
I might turn up the reg to try for better spread 🙂
@@VikingAirgunner I have the wheel at 15, the micro is at 2.9 and the valve at 4. The fps spread is practically non-existent ; between 967-970. So it's super puzzling that the accuracy is pretty poor, being a 3cm spread at a only 30m ? I don't think I need to turn up the regulator, because 970 fps with 85 bar keeps the system unstressed. Not sure what to try next.........maybe wait for warmer weather :)
@@nonickname6154 There is a very positive effect with the warmer weather 🤗
If Im to compare the mk2 and the M3 I find the valve to be much more sensitive. Like an 8th of a turn really makes a big difference 😯
@@nonickname6154 If your groups are like that with that nearly perfect spread, I would say that you dont have the right velocity 🤔
Please excuse my ignorance but how much does the long appendage under the barrel affect accuracy
Thats a very good question! And actually a question that I should have thought about before shooting.
It goes like this -
Any change done to a gun will contribute to a change in the "vibration image" of the gun. So things like a new barrel or adding carbon fiber to the barrel like sleeves or a barrel housing. Those are some of the big things that will cause the vibrations to change quite alot.
Then there are smaller things like a new lighter or heavier scope. Change in the mounts are also a factor.
Then there are the small things and not things that I have my focus at, but I heard that some olympic shooters do. How much you tighten the screws on that gun....Im not to comment further on that, but just to give a picture of how far you can take it.
As for your question-
Yes there is change in vibrations by attaching that chronograph on a pole like this. But by removing the chrono from the barrel where some attach is, there is a huge difference. And by using carbon fiber pole like mine it dampens the vibrations even better.
Any gun has vibrations and the beauty of it is that we can tune our guns to be in harmony so the changes that we do are evened out
Best regards
Peter P
Hi bro...i use m3 600mm superior factory std barrel and if using carbon fibre sleeve can it increase the accuracy?
Hi man
I theory, yes. The vibrations in the CF is much less than in the standard alu. I have never done an actual test on the subject and I would imagine that such a test would not show much difference.
But I believe that shooting lots of groups the avarage group size would decrease, so this is why I have done the change on my 600 mm. And the longer the barrel the greater the effect - so CF on the way for my 700 mm aswell 😀
Excellent video Peter, could you encourage your friend to start making Carbon Fibre barrels in 700mm , I am sure there would be great demand 👍
Actually I think that he as one waiting for me all ready 😀 So just ask him - Im sure that he would make you one 🙂
Sharing my experience . I purchased a carbon sleeve in the US offered by FX . Instead of just sliding the sleeve in or gluing the sleeve in over the barrel I opted to put a thick silicone grease on the barrel and sleeve and slowly slide it into place .
Later if you find it doesn’t help you you can easily remove it .
My results have been mixed only because I shoot a lighter pellet and my speed didn’t contribute to much harmonics to begin with . You never know until you try it .
Test em’ both !
Great video as usual Peter! But it seems impossible to get a hold of the 600mm .177 superior liner in the US. Are they being produced by FX and sold to the general public world wide? Where can I get one?
I havent been able to find just the liner, but both Krale and Huma-Air has the full barrel kit i both 600mm and 700mm🙂
@@VikingAirgunner thank you
Hi, I purchased a Kervan Airboss K1 25 cal FPS is 1100 and FPE is 60. Barrel length is 22.8 inches.
I would like to shoot both slugs and pellets, but how do you decide which of the two FX barrels to purchase?
Also, will the carbon fiber sleeve fit my gun? Where can I purchase it?
The FX Superior STX Heavy Liner compared to the FX Superior Smooth Twist X Heavy Barrel Liner?
Thank you
I am not familar with that gun and I think you should make sure if a liner from FX will fit your gun.
Liners shoot very different when you compare 177 to other calibers, so I cant really say anything about the 25 cal. since I only shoot 177.
@@VikingAirgunner Ok. Thanks for getting back to me. I study economics. The name of your TH-cam channel reminds me of a book that’s very interesting. It is called Viking Economics which basically explains why social democracy and democratic socialism completely out perform free market capitalism in every metric.
The US is a result of them shifting more and more to free market capitalist system which has been a disaster for the US and much of the world socially and economically. If you can find it, it’s a good read.
Great video, I think there's a misconception about accuracy and length of barrels, for air rifles a longer barrel gives more power as the projectile as more runway to eccelarate, staying in the barrel longer, downside is any movement from shooter as a greater chance of transferring to projectile result in accuracy inconsistencies, shorter barrel projectile spends less time in barrel, more suited to off hand shooting
I follow your idea.
My experience with longer barrels has given me much better accuracy 🙂
But at some point I will test out the 600 mm again, so lets see 🙂
@@VikingAirgunner I think for bench rest shooting 600/700mm provide better air efficiency but for woods walking, stalking a 500mm Wildcat or Impact really come into there own,from your testing your not loosing much velocity from 600mm compared to 700mm.
Wonder what barrel lengths are preferred in bench rest competitions
to someone who predominately hunts in woods, farms etc.
@@drekceldude walking in the woods the Wildcat is a clear winner - even if I have a 600 mm barrel on it. The Impact with the 700 mm is way too long and heavy!
Im not 100% sure what barrels are most used in competition, but I am sure that the longer barrels are the most common - at least on the Impact. On the Crown with the way the barrel is attached the longer barrels might create too much vibration - but then again we have the barrel tuner 🤓
Nice videos. I order m3 in august, i shoud get it this mounth. I order hume transfer port, do i need power kit or any thing else too shoot the slugs?
Great that you ordered an M3 🙂
And good idea with the Huma dual hole transfer port!
The power Kit should not nesecary. But a pin probe is best if you want to shoot slugs 🙂
Ohh and the carbon fiber barrel liner sleeve. Also a very good thing to install.
@@VikingAirgunner I will order. Thank for fast ansers.

Hej Peter.
Er det muligt at komme med ud og skyde i skoven, savner et sted at skyde min impact M3 ind på stor afstand.
Det kunne være hyggeligt, men skoven tilhører (desværre) ikke mig, så jeg kan ikke rigtigt tage andre med. Stefan er den eneste, der har fået lov til at joine mig.
Jeg er dog på udkig efter et sted mere, hvor jeg håber at kunne have gæster med 🙂
@@VikingAirgunner ja det kunne det, der er ikke mange steder hvor man kan få lidt rækkevidde. Vil selv gerne skyde ud på 200m + og venter på at kunne opgradere til 800mm
Good shooting I only shoot 177 it's good your getting that distance and the accuracy It gives me hope for my setup 👍
Thanks Will 🙂 It is defenately possible - with my spread it should be possible for anyone to do 😀
Could you make 500mm vs 600mm with slugs accuracy wise? That would be great!
Over the next months there will be lots of accuracy testing 🤗
hi Peter, excellent video, like many of the others you make...
I'm interested, the CF barrel housing, in how it improves barrel vibrations.
Is it possible to show how it works, and the structure as it is made?
I already sent an email to Stefan to get one for me, I still haven't received a reply..You can give Stefan a shout
greetings and thanks
Thank you so much 🙂
As for Stefan I will give him a heads up☝️
Im not into how the proces is around manufactoring, but I will have it on my M3 in a near future and I will be sure to evaluate it 🤗
@@TheVllade Thats a great idea 🤗
What version Accutec bipod are you using there ?
It is the FC-4 G2
I have a video about it 🙂
Hello Peter just watched some of your freediving videos Waw very impressive I thought I was doing good getting down 20 meters with my speargun you and Ted should get together I don't no if you shoot fish but I think you would be very good at it 👍
Thanks Will 🙂
20 m is a solid depth for spearfishing! I actually dont think that I ever went that deep with a speargun 🤔
I mainly did freediving and then just a bit of spearfishing. But some of the best experiences in the water was when just diving for fun and exploring. Eagle rays, mantas and deepsea baracudas... Memories buddy 🤗
@@VikingAirgunner yes good times 👍
It seems to me that getting the maximum FPS from the 700mm, with all other things being equal, would require opening the valve adjuster to push the pellet farther to compensate for the additional barrel length.
True! I dont know if you have seen my tuning video on my channel? In that video Im going into detail about the adjustment of the front valve 🙂
Thanks for your comment 🤗
Hi, yesterday finally after 5 months came FX impact M3 .177, 600mm barrel, but surprised me that the barrel did not have a dual port? and the upper barrel ending in the thread on which the damper is mounted has a large hole up to 9.7 mm? Please, you got it like? Friends have only 6.3mm that hole at 5.5, so they have a quieter shot!
Congrats on the new gun mate 🤗 I was also surprised that it only comes with the pellet transfer port as standard, but luckily it is a quick change with the Huma.
As for the hole - I asume that it is the diameter of the hole in the jam nut you are refering to? Mine is 6,35 mm.
@@VikingAirgunner thank you for the answer, yes it's the diameter of the lock nut and I don't understand what it's so big for .177
@@MrMartinzatko I actually never thought about it 🤔
@@VikingAirgunner interestingly, FX Maverick has a dual port automatically and no FX impact.
@@MrMartinzatko In 177?
i want to buy fx airgun so which one butter of in this model's for long range hunting .shooting.. i ask first which cal i get?. 177 cal &. 22cal
(1) fxwildcate mk3
(2)maverick
(3)impact m3
(4)impact mk2
i have no idea i purchase first time fx airgun my old model is marauder gen 2.. so i want to get update model in fx... please please help me for buying in this rifal
For hunting the. 22 is best. More ft lbs.
As for wich model is depends what kind of hunting. A M3 with a 800 mm barrel might be difficult to carry around, but for the long distances and from a fixed position it would be perfect.
Small tight places or wandering in places with thick vegetation a Wildcat would be good.
But my advise is to watch alot of videos and listen to the guys who does alot of hunting for their Experiences.
Hope that you will find the best gun for your taste 🙂

Ok I’ll take a look thanks, videos very helpful for what I’m looking for, always explained on point 👍🏻
Where can i buy a 600mm Carbon fiber barrel for my M3.
Hi Frank
I did a video on the 500 mm and the 600 mm. You can find some contact info in the discription of the video.
He is not always replying, so have patience if you write him 🙂
Personally I think that with the impact you get better results when you work at high pressures, I do want to leave it at 990fps, I put the regulator at 160-170 bar which gives me more than 1040 fps, then I close the air flow to i get 990fps. This way I get the difference between shots to 1-3 fps , I like to work with high pressures because the power curve is more efficient, and there is less vibration when the air passage is more close. That's my opinion
I have .30 cal
Thats a good point Tom!
I really like the idea of turning down the reg to get more shots, but I might be too low at the moment...But with the quick adjustment system at 2,5 I dont think that it makes significently big vibrations.
But maybe 10 bar more on the reg and a bit down on the hammer for me 😉
I doubt that your slugs would go very fast with 110 bar on the reg 😂
Have a great sunday 🙂
@@VikingAirgunner Of course, in .177 you don't need as much pressure because the weight of the ammunition is much lower. I forgot to say that with this method it gives a stronger but shorter air blast, so I need less air because with the strong air pressure I get the desired speed without residual air behind the slug. Good Sunday to you too.
I wonder if i should order a 700mm barrel, you stil using it? Im gonna order a carbon barrel sleeve and a tensioner kit anyway so i could just as easy change the barrel at the same time.
I have actually just been testing the 700 mm again today and hoping that I could make it perform, but saddly it was not the case 🙄
My advise is to save your money and if you want a barrel tensioner kit you can cut it down to fit your 600 mm liner 🤗
Havent done it yet but as soon as I find the tools to cut it down precisely, I will do it 🤓
@@VikingAirgunner I would imagine any shipyard could do it, they have tools to fine machine almost anything. If not then a tube/pipe cutter would be my bet. You know the types that swirl around the pipe when you cut it? But im gonna do your suggestion, i'm gonna order a tensioner kit and a carbon sleeve and stiffen up the 600mm instead.
@@trulsvian I think that you would be disappointed with the 700 mm. I have heard quite a few telling the same thing about it, so I guess that its not just me being bad at the tuning 😃
I cut it down today and pretty happy with the result 🤗
@@VikingAirgunner I wil follow your advice and keep the 600mm:)
That is quit a spread, I am sure you will get it figured out!

@@VikingAirgunner I am in the process of trying to figure out which .22 barrel liner kit in 700mm I should get. I am not shooting an FX but a Kral Jumbo that has been modified for 50fpe, I suspect with the new liner adapter with duel transfer ports I am going to gain energy due to the extra 100mm of barrel and the new duel ports, but don't know if I should go superior or superior super light. My Fpe is my limiting factor. Do you have any experience with the super light liner?

Hello, thank you very much for the video, but there is something that happened to us that I cannot resolve.

Hey Osvaldo
Working on the valve is a very delicate area. I usually turn it 1/8 of a turn between each test to find the right spot.
Wich length of barrel are u using and with kind? Slug liner or standard superior?

@@osvaldogomez999 I just might take you up on that invitation some day - thank you mate 🙂
I wish that I could help you better, but I think that the cal 22 is much different from 177, so I better not expose myself as too clever 😃
But have you tried to turn up the velocity?
Ted Biers last video he was shooting excellent groups at 1100 fps 😳
It might not be nessecary to go that high, but he was shooting 31.5 gr NSA cal 216.5.
My own recent experience that I probably might cover in a video, is that I Went above 1000 fps in the 700 mm liner. I have had big issues with the spread in that liner, but going 1000+ it helped alot - and accuracy seem to be good. Only tested at 34 m so far, but it looks promising, so it might be the road forward for you aswell 🤔
@@VikingAirgunner well, thank you very much, I don't want to take up any more of your time, it's cal .25, ours, my partner.

@@VikingAirgunner had a same problem with my m3, you can pm and I can write what helped me (985fps/std 2.6,spread 13)
@@slintik what is your contact info?
Awesome video buddy 👍longer barrel for lower reg pressure but you have to balance everything reg ,power wheel, valve adjustment everything has to be in balance.... I had that same problem where my spread was all over the place with my 25 cal 700mm it would shoot 950 then it would go up to 990 fps it was crazy but I had my reg at 120 bar so all i did was raise my reg pressure to 135 everything started working together good luck ... but to me you have very accurate 177 cal 700mm gun my friend thanks for sharing bsafe buddy
Hi Chris
Thanks for your advise 🤗 Maybe I should try that path. I tried it, but Im sure that I can be much more thorough.
For now I have been focused on the valve wich has been positive, but I think that you are right.
Thanks again mate 🤗
100 m, 5 shot with 2.2cm grouping it's not impossible ... I had 8x shot at 90meters using 690cm Lothar Walther barrel and it was also 2.2 cm on grouping.
I was using JSB Knock Out 13.47 grain (.177)
If that's a huma moderator that's probably the cause of your extreme spread being so bad had same problem switched to a donnyfl no other changes were made tightened right up went from 30-40 to under 10
There is no doubt that it has an effect when switching moderators.
You should check out my video on spread and velocity in the longer barrels. This gives a good picture of the issue 🙂
Not a bad group for a .177 projectile!
Thanks James 🙂
I will picking up the FX Impact 3 with .22 slug liner in the near future from my local Airgun retailer.
@@jamesbrownmiller808 You really have something to look forward to 🙂
@@VikingAirgunner for many years one would think a place like the Dallas and Fort Worth, Texas area should have several high end Airgun retailers ( we do have the Airforce airgun manufacturer in the area but they don’t have a retail store). In the past couple of weeks I did a google map search and behold, what did I find FT airguns literally the shop is in my backyard, to be exact 2.53 miles south of where I live ( right across the lake I live near) my wish has come true. Hopefully in the next year the owner will have has Airgun store and range built( this will be an Airgun only range)! Apparently the building plans have been approved with the city.
@@jamesbrownmiller808 That is fantstic!!!
So he is also a FX dealer?
I know that the bigger calipers are popular in the US. And I would probably be into to them aswell if I was living there. But the 22 seems like a perfect size. Ammo not too expensive, air consumption relatively low and enough knock down power for most hunting.
I was just told yesterday that an old military 200 m shooting range like a mile away was approved for airgunning, so now I just hope to be able to go there soon 😎
I agree that chasing FPS itself is not interesting, but your results where very surprising...
And I can truely confess that I didnt expect a result like that before starting shooting. But getting control over the spread will ensure the groups to be closer to this one every time.
@@VikingAirgunner yeah, the spread I am sure also can be tuned. But I did expect that you would gain quite a lot of FPS... I am not used to .177 tho, maybe it does not benefit from a longer barrel?
@@mikaelbackstrom The gain between the 500mm and the 600 mm was 46 fps, so I also expected more. Maybe if the reg was set a bit higher it would give a different result.
I think with a longer barrel you need to fine tune it.
Every barrel needs fine tuning, but the 700 mm liner has shown to be VERY difficult to get a decent spread from. And especially with the dual hole transfer port.
Actually I changed back to the original transfer port on both barrels, but still the 700 mm is hard/impossible for me to tune. So now Im back to the 600 with a very low spread.
@@VikingAirgunner I wonder how the 800 mm will be? Alot of good reviews out about 20 fps more with the same settings.
@@robbypro3370 I dont think that it will only be available in the bigger calibers 🤔
But as long as the barrel can be controlled a longer barrel makes sense in my world 😎
I don’t think you’re a cheater I think that’s a good group I think we can get you a title group if you polish that barrel amazing air guns can show you how to do it if you need me to explain more I will definitely do a video on FX liners for you I think you could get it under a half inch group
Thanks mate 🙂
Thats a good idea for a video! What are your experiences with polishing the liner?
there is something wrong there mate. i went from a 500mm to the 700mm in my .177 impact mk1 and it went from 865 fps (jsb 10.34) to 930 fps with no dual transfer port or pin probe
sorry forgot to mention that wen the barrel kit arrived the steel part on the transfer port side was loose and i had to loktiite it
Im not really sure where you are going with this info? Could you specify a bit closer please? 🙂
@@VikingAirgunner its either your first regulator went bad or the part that your dual transfer port screws on is loose as well. there is something wrong with your ES .also i emailed your friend about a carbon liner housing but no response
@@tromplee6107 That could make sense 🙂 Thanks for your suggestion 🙂
600mm好还是700mm好呢
我还没有测试 600 毫米的精度，但我会在某个时候测试。 但是，我很确定 700 毫米是最好的。 无论是耗气量还是精度
谢谢收看

I think when your shooting possibly not giving enough time for plenums to refill, making you FPS AND FPE'S LOWER???
GOING FROM 988 TO 968 ON A DUAL REG SHOULDN'T HAPPEN! I'm just guessing and new to Chanel as of today, are you in Germany? Plus do they allow the airguns on full power like in America? I know in England they turn them way down, which i can't understand why anyone would buy such an expensive gun when only allowed 11 FPE,considering almost all guns are pretty accurate at 50ft
Hi Scott and welcome 🙂
You are completely right about the wait between shots. Its a good idea to wait for the plenum to fill.
I did a video on Spread and Velocity. It gives some good info on the subject 🙂
I live in Denmark and we have no restrictions on airguns. We do need a hunting licence for anything bigger than 177, but I like this caliber 😃
Its 177.
Where’s 600mm group test ,man ?!!!
Its commin, its commin, I promise 😃
Actually I have a grand test of many different liners. STX, STX Superior and both 500 mm, 600 mm and 700 mm, but its gonna be another couple of months, so I hope that you will be patient my friend 🤗
Fastest was 20fps faster. Pcp needs to be properly tuned. That spread tells me something isn't running 100%
Thanks for the comment on this rather old video - made me watch it again to remember making it.
To answer your comment, you are SO right that something was off! I struggled more than you can ever imagine to control the spread on the 700 mm STX Superior liner. It seemed to work well with higher speeds, but since we know that higher doesnt have a good effect on accuracy, it was not the solution. Changing the liner into the heavy liner was☝️🤓
Check out my newer videos for more facts on this.
Conclusion after having used the STX Superior liner was that it was able to shoot some decent groups - but felt more like luck than skill!
So for anyone reading this: AVOID the 700 mm STX Superior liner in 177 and go for the Heavy liner!
Problem solved 😎
The 600mm barrel lenght is more acuracy than 700mm
Ok what are your results with both? 🙂
Not a cheat I’m afraid 🤣. I too can get those results with slugs 😉
DAMN!!! I was hoping to be called one 😂
It is so satisfying to get those groups. What ammo are u using?
U need 150 bar to close that valve faster a try it
My experience with high reg preasures is that it will result in bigger spread and less accuracy. It might be different in other calibers.
High reg and low hammer , helps the valve close fast I heard many times so this stops Any air distortion for the pellet when it leaves the barrel
@@ptescreen18 I am aquinted with the theory but my in my experience it does not give better accuracy - in fact the oposite.
I always test theroies.
Nice one... Keep more coming.. your new subscriber here.... Can you please sell me one barrel?....
Hey and welcome aboard 😃
I only have the barrels that I use, but I am sure that you can find a barrel of your liking 🙂
To many ahh sory no offensive 😆
Doing my best brother 😉
Thanks for watching 🤗
