This is a video that I know most people will benefit from I know that I just did , been weighting for a video like this one to explain this procedure and you did it well Ernest . Thanks buddy .
Looking at your post which is one year old , have you done this tune process and how was your result ? I have my MKII on the way and want to know everything about this PCP to get the best accuracy with a given slug , I will be purchasing the slug power kit to get a little extra velocity !
@@JackAgainski I added the Huma transfer port & the FX slug probe since my purchase with a power setting at 115 bar ! With a 23 grain .218 NSA slug in .22 caliber and a setting of 5 on the hammer adjuster I’m getting 958 FPS ! With this setup I get a 3/8 group at 40 yards and just under 1 inch at 105 yards . I plan on testing a 31 grain .218 NSA slug to shoot @ 940 FPS in the future .
@@JackAgainski the MKII comes with a superior liner that shoots Diabolo & slugs well up to a certain gram , I may need to move up to a heavy barrel for slugs over 28 grains achieving speeds of 950 FPS .
Thank you for doing this video is Ernest. It means a lot to a lot of us. Speaking for myself I personally love my impact and never regretted my purchase, I’m just glad that with FX his help and your master classes I’ll definitely get the most out of my impact. Thanks again.
I love FX so much but can’t own it’s.. but still in love it’s..here in Thailand so expensive...I will follow ur channel keep doing uploads more about FX.. thank you sir.. fan of Fx..
Ernest, this is very nice tutorial clip! Thanbk you very much, this will help a lot to everybody... I hope we can see soon guid lines for every size of pellets and slugs... Greatly appreciate you Masterclasses.
@@jwollheim 5 broken cocking levers, 2 valves, bad gauges , poor machining on block caused bad pellet probe alignment, I got one of the poorly chamfered pellet probes too, and the power plenum leaked. I had to pay the shipping on almost all the returns, so I am down hundreds there too. They never fixed it ,after 6 tries I did it myself and now it works. FX are totally incompetent.
I've watched your entire series, I think it's fantastic. Please do a video on rebuilding the FX Dreamline. I will use that video to make a decision on whether I buy one or not. Thank you very much.
I am about to buy my first FX Impact MKII and am watching everything I can find on tuning. I would greatly appreciate it if you would make a more basic video than this one. Maybe explain why you are doing what you are doing, how the reg pressure interacts with the hammer adjustment wheel, why you do them in the order you did, etc. Why did you start at 920 and then drop down? Where did you come up with those numbers and why? Basic stuff that you guy take for granted, still needs explaining for those of us who are still learning. Thank you.
You are a good teacher for this . It appears to be you have done this more than once . Nice job . Thank you for sharing your knowledge and experience .
Thanks for the video. I thought I knew where you were going with the tune - keep valve and hammer spring maxed and increase reg pressure until 920 fps was achieved and then back off the hammer spring to the ~900 fps range. I was wrong. Instead of backing off the hammer spring, you closed the valve a bit to drop fps to 900 range. I'm wondering why? Seemed to me that a bit lower hammer spring setting would have been better for the rifle. So why the valve adjustment instead?
Thank you for this video Ernest ! Could you please do a video like this for JSB MKII and the .25 cal Crown? Or maybe with the slug liner? After watching and doing what you said I have my crown tuned in nicely. Thanks again. I would still watch if you did a crown video.
Thank you! Plz make the same video for 25cal shooting jsb mk2’s 34 grain 700mm barrel! What feet per second do you recommend for efficiency and acuracy! Thank you
Stay below 59.6 fpe for best accuracy AND power combination then tune down, not up, to find the barrels harmonic resonance, which will be between 5 to 6 times the pellet speed at the muzzle, which pellet speed will be less than 78% the speed of sound at 26 degree Celsius. Regulator pressure will be around 145 Bar +/- 5 Bar, maybe a bit more. set your hammer spring preload tension half-way between full and minimum, as well as your valve spring. You will get the best equilibrium once you adjust your regulator pressure to get a hair below 59.6 fpe, now the fun part is to tune down, but not up to find your barrel's harmonic resonance and tune to exactly 5-1/5 of your pellet's velocity at the muzzle. All barrels, even from same lot manufactures one before the other will have different harmonic resonances, although close, but not exact. Besides a chronograph, a set of piezo sensors along the barrel and a digital storage oscilloscope, you can find the eluding resonant frequency, but once you remove the sensors, the resonant frequency will change by I don't know exactly how much, but you can deduce it by shooting groups above and below the tuned down velocity. Your the trainer and all athletes as well as guns are not the same, but this is why we shoot. Enjoy the sport. Stay safe and God speed.
I would like to know this as well. What is fpe? Is that metric? I am chrono at 960 FPS with 25 grain jsbs, 700 mm mkii pp. I am getting sub moa. I assume from where I am I just start working 10 shot groups for each setting on the power wheel, then look for the tightest group, but I don’t really understand the interaction and adjustment of the the two for optimization. I understand harmonic tuning for my center fire precision guns, but I am missing something on these air guns.
This is an eye-opener for a lot of People. I would be very happy if Mr Rowe could make the same video for the FX Dreamline. It would be very nice to know if you can fine tune the transfer port. The wheel on the dreamline only has three fixed settings.
Hi Earnest, I just got my FX Impact MKII in .22 cal with the new "Power Plenum" regulator. My question is - Do the regulator adjustments you show in this video work the same or are they adjusted differently?
Absolutely brilliant. So clear and easy to understand and do ourselves. I have couple questions. In uk we have to stick to sub 12ft/lbs. Would you say this is still worth doing for us? I know my given pellet weight so could easily find the fps I want to achieve. Also on my impact m3 I set the micro adjuster but after about 50 pellets it’s moved in and I have to reset it. Is this normal? Should I put a drop of locktight blue on it to hold it?
Thanks Ernie! So much relevant and good info, been struggling to fine tune my slug liner in .22 but this was certainly most satisfying to watch and very educational. Sure I should get my Imact shooting slugs like a beast at no time! Regards from South Africa!!! FYI All other comments/watchers ( if i might call it that ), same goes for crown,dreamline etc...
Thank you for the video. I just received my barrel change kit (.22/500mm) for my Impact X MK2. I am going from a 600mm .30 to a 500mm .22 and I have a couple questions please sir. Since I will likely be going in the opposite direction to what you presented in this video do need to unscrew the bottle before each/every/any time I adjust the reg pressure down (clockwise)? In going from .30 cal to .22 / (18 gr pellet) and the shorter barrel, would you start by lowering the reg pressure from its current setting of ~145ish to around 130 -135psi and fine tune downward or would it be better to initially drop the reg more and work my way up (then back down) like you did in this video? What would I do initially with the hammer spring for each senario? Thank you for your time.
I'm buying second hand mk1 impact with a huma reg on it and a stock 600 mm barrel with pellet liner. I haven't installed anything else. What's the maximum energy I can expect out of a .22 cal gun? I intend to shoot slugs with it.
Very good, Please would it be possiable to make an informed type of video with the mk2, with the power plenum. Showing how to set it up, just as in this video.
Thanks Ernest, that's awesome. That's really scientific with all those instruments to calibrate it. I remember when I was in the Philippines I just tried to approximate the spring tension of the air rifle hammer vs the CO2 tank air pressure, and it was a long process of trial and error, and patience. The FX M3 is really amazing, one of the best air rifle so far when it comes to fine tuning and accuracy. Have a great day Ernest and God bless!
Thanks Learned lots here! Curious... what would i use the hammer spring adjustment wheel for? since the adjustments are so course? All these tune videos show it on max. the set screw appears to bias the hammer spring tension between the the course settings like 4 and 5 or 5 and MAX. But why make the hammer spring wheel with such course adjustments? a redesign of the gun so i can fine adjust without need of Allen key (and taking off the stock, Crown) for example
Great video Ernest. what is the cc in that small plenum? After this tune at 130 bar regulator pressure, Macro at Max, micro pre-load at 18 mm, valve spring 1-1/2 lines, or better yet 7.5 mm; how many shots from 250 Bar bottle to falling off regulator? And once falling off the regulator, how high does the next number of shots climb to in velocity? Lastly, what is the hammer spring specifications? such as length, wire diameter, number of coils, inside diameter, and if you would know the spring-K value or type of metal. Same for the valve spring. If you do not have such data, how can I purchase a valve and hammer spring for my analysis without the included gun? Thank you
A real master! Hello Ernest, can you tell me please, it is difficult to solve an air leak on the macro wheel, I bought an FX Impact M3 Sniper from Aeron Czech Republic and I am facing this problem! Air leaks are common in brand new FX weapons, could I solve this problem myself, how complicated is it? Is there an oring out there, it could be a serious manufacturing problem, what do you say, should I send it back to the people who sold it to me? Thanks in advance!
This instructional video is outstanding! I learned more from this single video than from all other sources combined. very well done! thank you Ernest!!
Hi there Earnest, I was wondering if you do tuning for a fee? I have a fx impact mk2 .25cal and would like to get it tune. Here on Minnesota I just couldn't find anyone who can tune air rifle especially fx air rifle. Please let me know if you are doing this 🙏. My name is Jack Xiong.
I have just received my 25 cal 700mm Impact X mkII. The gun is not shooting correctly out of the box. Firstly the sound is all wrong it is just a tight click when fired and the velocity is 355 fps with JSB Exact 25.4 grain with the power wheel set at max. Thank you for the tuning tips and I understand how I can probably tune the gun to get the correct performance but I am concerned that something may be wrong with the gun since the performance is so poor without any adjustments made to the factory tune by me. The reg pressure is set at 130 and I have filled the bottle to 220 bar. The gun was supplied with the Side Shot high capacity magazine and I have fired over 100 shots to see if there was just a break in required. It has consistently shot around 350 fps for the initial 100 shots.Please advise if I should return the gun or attempt to tune it. Thank you.
Thank you! Seeing it done is the best way to learn it and although I do not have the Impact I think most of what I saw will help me with my first generation Crown. It would be nice to see this done with the Crown!
I’m having a problem with 30 cal fx impact 700m barrel with Stx barrel. I’m at 123 or so on reg. I get a good group but I get 4-6” flyers with fox 44g at 60 yards. I’m at avg 874fps Where should I start? I had old barrel on and Utah Airguns put new stx barrel on it and I’m having issue with flyers
Hello sir I have fix impact 35 caliber just got it last week My speed only 854 FPS My regulator 145 par So those pellet 81.02 gr actually have Did I supposed raise it up Cause when I got it from uta the sand a sticker Have Pressure sat up on 885 What is your advice your opinion. Thank you
Thanks Ernest and FX! Anyone else find the coincidence of the hammerspring adjustment measurement of 18.1 mm for 18.1 grain pellets interesting? I’m sure that none of the other caliber adjustments would line up so OCD! Thanks again.
This guy has got to be the most chilled and laid back instructor ever. Appreciate the video. Very informative.
Ernest it was a real pleasure to meet you today. I'm reviewing your video in preparation for tuning my new Impact. Good stuff. Thanks Sam;
You are TRULY thee FX IMPACT GURU! Thanks much for taking the time to share your knowledge!

Yes 100% do it for the Crown
thanks Ernest ... fx is to be complimented for this "value added" information on the fx impact ... on to the crown ...
Thank you for your patience with us amateurs, that was an excellent presentation.
Excellent Ernest!!! Lots of people were waiting for this. 😀 Thank you!!

When they say max out hammer spring. Do they mean max out velocity or keep winding screw in until it still in full contact with cam
Does that work with the power plenum?
Hi great video just what we need it’s always a bit scary adjusting things, can I ask what different settings I need for .30 please.
Can you tune an M3 for slugs without the slug power kit ? Thanks for the info .
A good teacher. Even if I don't own a fx and probably never will. But they sure are awesome guns.

Hi and great work 😀
I wonderer why i only get 20 shoot from my fx impact mk2? Its not leaking air only my shoot is taking a lot of air.
Regards//Hans
How many feet per second do you leave it below the maximum speed that the regulated pressure gives???
Hello ernest. May i ask what does adjusting hammer spring tension do?
All great tips Ernest. Having a micrometer and chronograph are a must when tuning. Next up barrel indexing. lol

Is it the same for .25 cal?
Reg pressure 125?
I absolutely like the ways how you exhaust the air speed ,where to exjusting buton. Until we had the correct setting.😮
Hey Mr Rowe,
Have you stopped making vids on the cricket,
The ones you made were awesome.
I have a Impact MK2, .25 cal. Do I apply this method for the MK2? What fps should I go with? Thanks
How many numbers are the allens you use for power?
I’m having a problem with 30 cal fx impact 700m barrel with Stx barrel. I’m at 123 or so on reg. I get a good group but I get 4-6” flyers with fox 44g at 60 yards. I’m at avg 874fps
Where should I start?
I had old barrel on and Utah Airguns put new stx barrel on it and I’m having issue with flyers
Ernest is “AWESOME”!
Hello sir
I have fix impact 35 caliber just got it last week
My speed only 854 FPS
My regulator 145 par
So those pellet 81.02 gr actually have
Did I supposed raise it up
Cause when I got it from uta the sand a sticker
Have Pressure sat up on 885
What is your advice
your opinion.

Ernest thank you so much for this great video, watched it a few times excellent!
Thanks Ernest and FX! Anyone else find the coincidence of the hammerspring adjustment measurement of 18.1 mm for 18.1 grain pellets interesting? I’m sure that none of the other caliber adjustments would line up so OCD! Thanks again.
