The main advantage of a longer barrel is lower air consume for the same fps and same bullet weight. So, for full advantage, the hammer time must be lowered, also the regulator pressure. With a longer barrel, the pellet has more time to accelerate.
This is an informative video. Small fraternity of people with .177 impacts. I have a 600mm M3 and it is hard to find information on these, especially tunes. I had to frequently clean my liner (150 pellets) or I would loose accuracy. I did a mild polish and things improved (now needs cleaning every 250-400 pellets and much easier to clean). I won't try to polish anymore until I can find an spare STX superior 600 liner. So, yes, it is hard to find over here in the USA too. THANKS
Its interesting how there are different approaches to barrel cleaning. I have never cleaned my barrel unless just after getting a new one, but maybe the 600 mm is different than the 500mm 🤔
Totally weird, cause i have both .177, 22 and 25 cal for my Impact and only clean them once a year, and that is because i dismantle the gun to clean and change O rings. I feel that the more pellets/slugs goes through mine, the better it shoots....know it sound also weird. But again, liners all thought they should be the same from Factory they aren't.
I like your videos because you are pushing .177s! I’ve always had a love for them and I am building a .177 Impact to shoot them. Was thinking pellets, but a .177 slug gun might be fun!
Hey buddy 🙂 I have shot lots of pellets, but now that I have gotten into slugs it is just a completely different game. They made me change my mind about going to 22. And thanks for all of your comments 🤗 I really appreciate that 🙂 Have a nice weekend Best regards Peter P
Please consider making a detailed video that illustrates how one can achieve such tight extreme spreads and standard deviations with a .177 M3 w/ 600 mm barrel. I have not been able to get even close to the results you showed (1st string in this video). Even FX has indicated that achieving a tight extreme spread is challenging with .177, yet you guys are getting fantastic results. Please share your knowledge!
Thats defenately an idea for a video in the future. But my first thought about the thing is to have the harmonics in mind. So no crazy reg and not maxing out the hammer. I have noticed that the front valve has a completely different function on the M3. Can barely touch it before the velocity is affected, so myself being a relatively new owner of the M3 havent figured it out yet. So to be honest I dont feel fully equiped to teach yet. The MKll is a bit different, but I cant imagine me doing more videos on that since my focus in on the M3 now. -and the MKll soon to leave for another home 😀

Hello mate,did you measured your 500mm stx superrior liner, exact measures is it realy 500mm or is it 485mm,thank you,as i ordered a slug liner and its exactly 500mm the one i got supplied with my m4 compact is superrior stx 485mm...
Its been so long since I used the 500 mm liner, but I seems to remember the length was not actually 500 mm. I have no knowledge about the new liners like the heavy liner in that length 🤔
Hi V.A. and thanks for yet another great in analysis and comparison in .177 video. One think to point out though is that FX as far as I know are not producing the 600 mm in Superior Heavy, just standard. The Superior Heavy starts from .22 and up. Anyhow, I don´t care, cause I think tests I have done with the K.O and Wildmans in .177 and using the Superior standard , are okay for my groupings liking and using the 500 mm barrel. Will of course consider the longer 600mm cause the velocity is higher, but I have the feeling that cause of the lite slugs used in .177. the poi and groupings will be less accurate, the further the distance. if you catch my meaning. But slugs are definitely the way to go with .177 as they will travel longer and will, if of course tuned correctly have better groupings than pellets. Looking forward to perhaps a video where you compare the poi and groupings between the 5 and 600 mm. Great you brought with you Stefan the Wizard. Perhaps you can do a video on all the stuff He does for the Impact and perhaps other airguns as well. The only thing now to totally dress up the Impact with CF, is making the shroud, so you have the liner sleeve, the barrel carrier and then just needs the shroud. And by the way......Merry Belated Christmas to you and Your Loved ones! stay safe and shoot safe! ❄🎅🏻🎄🤶🏻☃🔫
Hi my friend You are right - the heavy liner is not available in the 177, but as you say the standard superior is doing the job. I havent really tested the 600mm on the longer distances yet. My groups are usually falling apart in the cold weather, so I imagine to do those videos in the spring. I cant imagine that I will go much beyond the 980 fps with the KO. They seem to perform really well at that velocity, but so nice to be able to turn down the reg - but lets see what the next couple of months will bring of experiences 😀 I hope that you had a nice Christmas and that you are ready for a new year - with all your new gear 😎

Hi friend well played, nice video big speed gain, I heard that if you put a longer gun you also gain in air consumption because you need less air to push lead, would you have been careful during your tests, thank you for sharing
Hi buddy 🙂 You are right! Actually you have the answer in the video bcs the perfect velocity of the ammo dont really change that much from 5 - 600 mm - at least that is not my experience. So if you gain 46 fps by changing from a 500 to a 600 mm liner, you dont have to shoot the 600 mm at this crazy speed. You turn down the power of the gun after installing the longer barrel and get the same speed as with the 500 mm, and thereby saving air 🤗 So the gain is to save air and hopefully improve accuracy. Testing in the upcommin months 😀
Salvation ; the friend I ordered my gun in 700mm following your video if you allow it when my video will be released, I will tag you and I will do precision tests I will check the grouping that I can do with it; thank you again for your video

Vídeos excelentes se poder colocar em tramitação porquês agradecimentos de todos 🇧🇷 pois muitos só bodem adimira governo muito ñ incentivador impostos daria para fazer muito
Apologies if I am mistaken but would a longer barrel not reduce velocity but increase accuracy and a shorter barrel length would increase velocity but decrease accuracy? Roughly speaking, you would assume the velocity of a projectile when leaving the barrel, would be the total energy coming into the barrel from the cylinder or regulator, minus the energy lost through friction and thermo dynamics of pushing the pellet through the barrel.. so, longer barrel means greater friction and energy loss while pellet is pushed over a longer barrel length, but the increase in stabilisation dynamics means more accuracy and the opposite would be true for shorter barrels, less energy loss from friction over shorter distance and more energy on the pellet resulting in higher exiting velocity, but lower stabilisation and accuracy.. I suspect that although you used two identical rifle models, the rifle fitted with the longer 600mm barrel had a slightly higher output rating on its regulator which was the reason for the 46 fps gain over the 500mm barrel as it would be almost impossible to ensure that two seperate regulators are manually tuned to identical output ratings to accurately compare velocity figures attributable to the barrel lengths as only factor.. In order to accurately test impacts to velocity from 500 to 600mm barrels, I would suggest you perform the test using the same rifle while swapping the barrels after each shot and then analyse the average ratings for shots from each barrel to nullify any differences from using two seperate regulators and rifle setups..
Thanks for your comment and your analysis 🙂 First I want to clearify that we only used the Mk2 for the testing of the two liners. You can watch the video again and you will see. As for your question the barrel is where the ammonition gains velocity. It does so through the entire length of the barrel, so using a longer barrel gives the slug a longer distance to pick up speed. You can compare it to a dragster trying to reach the maximum speed in 201 m and the exact same car on a 402 m. Same car (gun) same power (reg presure) 🙂

@@lassesarnhult9283 Ja det er for omstændigt med de større kalibre. Licens og lovgivning om anvendelse og opbevaring. Og så selvfølgelig forbrug af luft og de dyrere hagl. Så jeg er glad for 177 🙂
Hi. Please let your friend know to check his email box. We tried to reach out to him using email which you provided in the description but got no response yet. Thanks.
Thanks for telling me. I will tell him asap 🙂

Can .177 slugs take deer and hogs
With a head shot it might be possible, but I would never attempt it.
Without having any experience with hunting my guess is that it would take at least a 30 cal to ensure the shot to be as humane as possible.
There are lots of videos here on RUclips, so my advise is to seek more information.
Best regards and thanks for watching
