- In this video I am adressing the issues around the big spread that you might experience while shooting the longer barrels in your FX Impact. I am focusing on the .177 700 mm liner.
My focus in aimed at the transfer port, velocity and the weight of the slug.
In this video there is a segment about how to tune the FX Impact M3. This will be released in a seperate video shortly.
Enjoy
Peter P/Viking Airgunner
Very well done I'm learning to tune shooting slugs ,power wheel at 16 got 945 fps then went to micro till speed dropped then went back 2 clicks, then valve ended a 7 shot string 1st 938 next 6shots where 942 that is my sweet spot for slugs from my fx thanks very informative video and done the way I was taught. Shooting 25cal 700 barrel h&n 34gr
Did some problems with spread at 910 fps, turned up pressure to 110 bars and its much better thanks for some great information
Thanks again for another great video. I have a M3 177 with the 600mm. I've used the valve to gain speed but never tuned with it. Thanks for explaining tuning with the valve will definitely give it a go! Over a year ago SPAW here in the US started taking preorders on the 177 Superior Heavy Slug liners. I preordered one immediately. Short story, still waiting!!! I hope FX releases it soon before I decided to move onto a different platform. I didn't buy the M3 to shoot pellets as I have many other guns that do that well. FX, we need the 177 slug liner already!!!
I just saw the site with the pre order the other day, but I did not know that it had been up so long 😳
I saw fx USA announcing its arrival a few months ago, so Im pretty confident it will be here soon 🙂
Im happy that you liked my explanaition about the front valve. I tried to cover as much about the tuning as I knew, so happy to contribute 🙂
@@nigelbase1196 That is not me using a stealth account 🙂
Thank you, the tuning part was very informative!!☺️
I agree with you I had the same problem with both of my fx impact mk2 25 cal 700mm and fx impact m3 22 cal 700mm but now both are shooting awesome thanks for sharing your info be safe and shoot straight buddy 👍
@Antony Dala heavy superior slug liner I'm shooting 37 gr Zan at 995 fps 82 fpe at the moment. With the regular slug kit and Ernest Rowe dual port I tried the tungsten the huma slug kit and fir me it was wasting to much air with the regular slug kit I'm getting about 1 and 1/2 mags it's not much but I'm using that set up for hog hunting at 165 bar
Thank you man so much man I switched from pallets to slugs and I changed the transfer port to the dual transfer port I was getting inconsistent shot spread was big 76 !! I watched your video I went back to the single port I did some tuning no I'm sending h&n 23 grain
970fps with 5 shot string 1 inch group at 100 yard
That sound great 🤗
So happy that I could inspire you 🙂
Happy shooting buddy 😎
Brilliant video Peter ! I have a 177 FAC Mk 2 with 700mm barrel and using NSA 15 gr I get a spread between 919 to 946. I have the regulator around 100 bar, to keep the vigor down. Funny thing is that I get a few shots around 919, then a few around 946, then a few back down to 919 etc. Just fitted the Power Block and turned the regulator up to 108 bar and after adjusting the knob between the barrel & air cylinder to show about 3.5 rings - I'm getting good consistency around 956 ie +/- 4 fps. I'm settling for this based upon the size of the spreads before. Having said that - I'm sure I'll push for higher fps at some point . Next job is to try and get acceptable groups using the harmonic tuner on the tensioned barrel. Find your videos very inspiring to keep exploring different setups & options.
Thats an interesting development! And especially with the Power Block. Mine is just laying around since it was leaking when I installed it. Switching back it was tight again 🙄
Exciting to see if there is better accuracy after reaching higher velocities 🙂
I did a 10 shot string with my RTI prophet compact in. 177 with H&N baracuda match and had 9 out of 10 @900 feet and the last one was 898 feet I have never seen it befor and don't think I will again. Mad too see you doing the same over 1000 feet
I have heard nothing but good about the RTI Prophet, so Im sure that you will see such strings with matching accuracy again 😎
Glad to see you back . We all need a break sometime to regroup .
I continue to be faithful to the .177 for a number of reasons . Shot count being one of them . but for back yard target and small varmint dispatch it’s all you need and it’s quieter . It is more critical for the .177 with lighter pellets and slugs to keep you spread as close to zero as possible for accuracy.
One think we don’t talk about very much . the amount of wear and tear the o-rings , regulators and hammer valve assembly take to get big bore PCP’s to shoot the high velocities needed to send larger & heavier pellets or slugs down range . If you want reliability , the .177 is better .
I do worry for you though , once you get to that pentacle you may run out of things to do . 😂
Agree completely 🙂
Its funny how the number of videos has a direct connection to my declaining bank account 😂
It was nice to finally release a video again - I know it is kinda nerdy, so I guess that it reflects me 😃
@@VikingAirgunner I am spoiled with the Weihrauch trigger on my HW100S compared to my FX Impact . That is my next project . To look at the trigger mechanics and see if I can polish the sear and improve with zero creep and a clean break .
@@hotchihuahua1546 that is an interesting projekt ☝️
I remember the trigger on my childhood Diana 48 that was super easy to adjust from hard to feather light 😎
Great Video! Thank you very much for sharing.
Very informative, thanks for a great video
Gran trabajo amigo y muy buen video a resultado muy útil para entender las velocidades a las que uno desea tirar
Great informative video, thank you
Great video. I just purchased the M3 .22 caliber Sniper 700 mm barrel with heavy slug liner. Shooting JSB Knockouts 25.39 grain slugs. I have not found the accuracy I am looking for at 100 yards. I have also tried various other brands and weights from 23 g. to 30g. Shoots sub MOA at 50 yards, but 2.5 MOA average at 100 yards. Shooting 950 fps with a spread of around 6 fps. I have tried 950, 960, 970, 980, 990 FPS but no improvement in accuracy. I shoot my Daystate rifles at 1 MOA or less at 100 yards - 22 caliber using JSB pellets and slugs both 25.39 g. I use FX Impact 44 g slugs and JSB 50.1g pellets in 30 caliber. I will try your tuning tips and keep playing with the velocities. Thanks for taking the time to not only walk through your experiences, but to show the data in clear and simple summaries. Very well done.
Hi Daniel
Thank you for your comment - and sorry for my late reply.
There are so many variabels so it is hard to say what might be the issue with your gun on longer distances. But I hope that you will have better succes after tuning your gun using the method I showed 🙂
I have no experience with the bigger calibers, so I cant really give you the golden key 🤔
Usually when I have issues like yours it is the ammo - but again there are so many variables.
Best regards
Peter P
I revisited this post to give you a tip on improving the trigger feel on any FX Impact if you haven’t done it already .
If you ever remove the C1 to access the hammer & spring assembly , do this before putting everything back together .
By chucking the hammer and spring (housing )with a hand drill polish the face with a fine compound to a mirror finish !
This is the side the trigger assembly spring & hammer locks onto when you cock the gun . You will find it eliminates trigger creep and works smoother .
Thats a good trick 🤗
Thanks for sharing mate 😎
I agree with your statement at the end of the video. 👍
Lets hope that it will be a reality very soon 🙂
@@VikingAirgunner Absolutely, I think the worst thing is that the machine FX uses to make their liners is very easy to change to whatever twist rate you want. The same probably applies to the chocke.
My thinking is that FX wants people to shoot their new .177 slugs first and then the new liner will come only when people discover they are not as good as certain other manufacturers slugs. We haven't seen FX's new slugs yet either, so it will be a long period without improvements for us who shoot with slugs. 😒
My understanding of the M3 system is that if you gave someone else your settings, both regs, power wheel , quick tune and front valve they should get pretty much exactly the same speeds with same slugs/pellets. Probably why people ask you, but they require all settings. Nice video.
And you are not wrong, but you will almost certainly be a bit off on both the Quick tune system and the front valve.
I would defenately not guarantee that my settings would be 100 % succes for anyone else. They could be close but they would still have to do some fine tuning.
This actually isn't true.. too many variables. Altitude pressures weather conditions etc all will effect the outcome. I've tried punching in values other have used and it just didn't work. Got to see what works for your rifle
Great video, Thanks! What sort of tent do you use in this video?
Thanks man 🙂
It is a shelter like cabin that I built myself. You can see it in detail in the video I did about the JSB knockouts. Accuracy and expansion test 🙂
Pls do give the h&N 20grn slugs a try.. it may surprise you with its accuracy..
Hi Viking
I know this was filmed a year ago and I did watch it back then as I was looking for answers for my own M3 in .25cal. I had the exact same problem with FPS spreading vastly and grouping like a shot gun fired at a target. I purchased my rifle brand new in January 2023 and had to send it back 2 months later after trying several attempts to try and put it right myself. Unfortunately, the distributor/airsmith for the FX range in the UK are useless. They kept my rifle for 27 weeks and when I finally got it back it was hit and miss. They claimed that they had replaced both the heavy slug liner and the standard one but I think they were lying because when I took the barrel apart to fit a carbon sleeve in the standard one, it only had two O'rings instead of three and one of them was completely broken. Ideally I would have preferred a full refund but I persisted with hope that I can get it shooting the way it should. Anyway, here I am again going over your video again from a year ago trying to find answers for a fix to my problem. Wish you were in the UK.
Any ideas?
Hi buddy 🙂
Im sorry to hear about your problems. I actually also sent back my rifle which didnt fix anything.
What I did find out was that the 700 mm STX Superior liner was the problem. After switching to the heavy liner my spread went down and became acceptable. But I still have the experience of spread getting better with high velocities ☝️🤓
And also during the making of my videos with the Lothar Walther barrels.
Have a great weekend 🙂
Hi, thanks for a very detailed and explanatory video. I live in the states and I have the superior heavy liner which is the Slug liner? Are you saying you don't have access to this liner or we need a better slug liner? Thanks again!
Hey
I might be confused by the names of the liners - sorry for that 🤔
I dont know the difference between the heavy and the slug liner. And Im not even gonna try to guess 😃
In Europe we only have the STX Superior liners. So no specific liner for slugs like the heavy/slug liners.
FX USA announced a while ago that the slug liner is in the pipeline, so just waiting (kinda impatiently) for it to come out 😃
*And Im talking about the 177 cal 🙂
@Antony Dala I wanted to like your comment, but I dont like that we dont have the slug liner 😃
Fingers 🤞 that it will come out soon 🤗
matt dubber discussed this also. if the pellet/slug reaches the end of the barrel the valve should be off already. thats the most efficient tune you'll get to your pcp.. thats the basic of tuning a pcp rifle.
His video is very good. Ernest Rowe and 68 whiskey says about the same 🙂
hi
Great video to address the issues for .177, i have a one question
1. At what pressure is 2nd regulator ? and is the hammer stock one
2. An another issue being faced is the first 2 shot being lower than the remaining (post changing the mag) , have you also
encountered any similiar situation?
would appreciate your thoughts pls
The regulator preasure is different through the video. I think that I refer to it along the way.
My hammer is stock.
Ernest Rowe touches the subject about the changing velocities in some of his videos. He says that he always shoot 10 shots before starting his groups. My experience tells me 4 shots is usually enough. Im sure that it is down to where system warming up 🙂
This was a very good video. I wonder how the shot count is .177 with your tune ?
That set up is good small game set up , flat shooting.
Thank you Roger 🙂
I actually dont know my shot count 🤔
I agree. FX needs to get their shit together. To me, it's absurd to buy a gun for $2,000+ that doesn't perform optimally out of the box.
I actually dont mind that there is a specific liner for different ammo. Aslong as it is not like 7 different liners 😃
There have to be different liners with different ROTs for different projectiles. It's science! I like that they don't compromise and have one ROT liner that does everything okay and they have specific liners that perform fantastic for the specific applications.
Hey when you start talking about spread and velocity around 20:25 did you touch the second regulator anymore from the first time when you went from 110 or so to 125 im really just trying to understand everything lol and the reason you did that was because your spread was not ideal for you at the 985 ? Am I following you on that ?
When I turned up the regulator I was aiming for 125, but I only went to 118. Just decided to test it there.
In that segment it was all about finding the velocity so not really focusing on the spread. So here I was aiming for a maximum around 1005 fps so I could turn down the hammer and hit 985 fps with less stress on the system to make it more harmonic.
Hope that explanaition helped - if not just ask again 🙂
I wrenched a little on my maverick a few days ago, deciding to start low for a change at 960 or so FPS i had a fairly flat string ( 10 shots ) BUT ! One of the shots was substantially slower dropping 10 - 12 FPS.
Dont know if it is a wonky tin of the 13gr Ko slugs, but i dont think so as it repeated the behavior several times.
Anyway i will shoot the Maverick on Wednesday and probably also ramp up the speed some.
Praying my M8 dont have me pegged for too much work on the railroad, CUZ the weather so far look to be really good, so i would prefer to just shoot.
Just shoot man 😎😃🌞
I think that it is common with a flyer once in a while. Getting used to slugs we forgot how it was shooting pellets where there were much more flyers. So now that we forgot we think that it is the gun when it happens 😃
To also add... very interesting interesting! 😁
Hei Peter - bruker du pinprobe eller original probe ved test av STX Superior/STX Superior Heavy 700mm liner? Tore
Hej Tore
Jeg bruger altid pin probe 🙂
Excellent video! hey so I just bought an M3 like two months ago its a .25 Cal 600 mm barrel and its shooting at about 989 with 1st reg at 160 and second reg at 110 with power wheel at 16 and micro pretty much maxed as well and the valve probably on or past line 5 and its a rough 989 not harmonic at all very intense recoil so my question is if i put my second reg at 120 125 will I be able to hit a thousand fps 1000-1025 give or take like yours and then also be able to calm the gun down as well less kick etc.. its completely stock no upgrades thank you I appreciate it.
Hey 🙂
I am no expert on the 25 but from what I can imagine you are completely right in your assumption.
Is the 989 fps the maximum velocity at that reg preasure?
If it is - then try my way and turn up the 2nd reg a bit at the time untill you are able to hit around 20 fps above the 989 fps at the max and then turn down the power wheel till you hit the 989 fps again. In this way you will experience a much more harmonic gun 🙂
I hope that this will help you 😎
Best regards
Peter
@@VikingAirgunner thank you and yes thats like the max at that pressure yeah didn't think to go back down after turning up the reg that sounds perfect thank you thank you thank you!😁
I have the 25 cal and these are my settings. I get 1030 fps shooting 32 grain slugs. My 1st reg is set on 160, the 2nd reg is set at 135, vale is on line 4, micro on 4 and the macro on different settings. With my macro on 14 or 15 I get 1030 fps shooing 32 grain slugs. Shooting 27 grain pellets my max is 1090 fps. I usually set my macro on 6,7,8, 9, or 10 depending on the distance I'm shooting. Forgot to mention I have a 600mm barrel on my M3. Normally with my macro on 6 thru 10 my avg fps is 975 Hopes this helps. If I wee to set my 2nd reg on 170 and 1st reg on 190-200, I would be shooting well over 1100 fps but I don't need that much power because I normally shoot 100 yrds or less, but it's good to know I can get that much power if I start shooting the heavier slugs 40 grains and above.
Forgot to add that on a full fill I get 70-75 shots. Also I have not added anything to my gun, no power block, no slug liner, or hammer spring kit. Gun is straight out the box with me just tuning it. Also I'm shooting at a low attitude. I live in the South.
@@anthonygillespie7233 I have the 25 cal m3 600mm barrel and my reg settings are very close to yours front 150 rear almost 130 and my macro/micro and valve are pretty much same as yours, velocity close to the same too, do you have the 580cc bottle or the 480? using h&n 34 grain slugs at or over 1000 on 15/16 micro 4.5 stock m3. Thanks
Thanks for sharing Bro, nice 😎🤙
You are welcome buddy 🙂
@@VikingAirgunnerWhats your Instagram?
@@murakataairgunner I dont have an Instagram 🙂
@@VikingAirgunner i have many Question 🤣
@@murakataairgunner just ask. I will answer as well as I can 🙂
That’s interesting that when you increase the velocity the spread reduced.
So, to increase the velocity, you were raising the hammer spring tension using the power wheel up to the maximum number? Was the second reg still at 118bar?
Were you adjusting the front valve each time you raised the velocity (power wheel?) to get the slightly reduced speed then wind back out to get back to desired speed?
Its been a while since I did the video, so I cant really remember the exact procedure, but I didnt fine tune the gun for each setting. I seem to remember that I raised the reg preasure.
But after changing from the standard STX Superior liner that I was using in this video into the heavy liner the problems with the big spread disappeared. So if you - or anyone else are using the 700 mm stx superior liner - I will strongly advise you to change into the heavy liner if you are using slugs 🙂
@@VikingAirgunner thanks for your reply.
I have an M3 sniper (.22 700mm barrel) I have just purchased the superior heavy liner.
I was just wondering how you achieved such low spread.
So you were raising the reg pressure at each velocity increase but not tuning?
Or did you set it (as in the vid) to 118 bar and set the front valve so it was balanced then just adjusted the power wheel?
Sorry, I understand this was a while ago and may not remember!
@@iantcroft Yeah its been so long that I cant really remember - but for a low spread tune you can take a look at my tuning videos. In the newest one Im focusing alot on the front valve, but take a look at both videos to get the full picture of my approach to tuning 🙂
I remember lots more about those videos, but feel free to comment/ask in the comment section of those videos 🙂👍👍
@@VikingAirgunner thanks, will see if I can find those videos.
Hello there. Awesome video! What was your regulator at 1018 FPS?
I dont quite remember, but around 120 bar. Im pretty sure that it is mentioned in the video 🙂
Thanks for watching mate 😎
@@VikingAirgunner thanks
Where to buy 700mm barrel of 177 Calibre?
Here in Europe I will recommmend Krale. But wait for the heavy liner to arrive. Dont know if it will be better, but I will get it and test it 🙂
@@VikingAirgunner Thanks 🙏
I've always told everyone, don't chase numbers. The rifle should be allowed to show you what works for precision accuracy. Low ES/SD does NOT mean it will be accurate. My 25cal 980fps 34gr has 25fps ES & its insanely accurate. 30cal 44.5gr 1004fps 14ES (110 shots) again insanely accurate
I didn't know FX made a .177 700mm barrel ?
FX is treating .177 shooters like red headed step children (nothing against the red-haired people) 😁👍🏻
Yeah I guess that the bigger calibers are more popular world wide 😃
But Im doing my very Best to draw some attention in the direction of the 177 😃
I dont think that the STX Superior 700 mm liner was available all over the world. For sure not in the US.
I dont know if the 700 mm heavy liner is but I hope that it is 🤗
