FX Crown Harmonic Tuning Guide

[@JoePatABC]

Watched this a couple of days ago (it's May 2019) and immediately put the tuning technique to the test on my new .25 cal Brocock Bantam Sniper Magnum which has been giving me consistency issues since I got it. My feeling was that it was pushing the 25.39s at 940-960 fps and that the pellets simply don't have a low enough BC to remain stable at that speed. So, I've backed everything down and have been able to get some very nice, consistent statistics ending up with a 150 bar reg setting and a hammer spring adjustment that eventually produced an extreme spread of 3 fps and a standard deviation of 1 !!! That's not a typo... I'm real excited to get to the range tomorrow and see how this tune works at 100 yards which is what I bought the gun specifically to do as a bench gun. Anyway TY for the detailed procedural, it was more than a little helpful and by far the most easily understood of the very few explanations on Harmonic Tuning that are out there. Cheers Joe P.

Great job meathead! I think this is a first for youtube and fx. Rather than just do the average breakdown and concept of tuning, you filmed and edited(very nicely) the whole thing. This is sooo important and deserves all the praise i hope you receive for it. This helped tremendously as im a very visual learner, its one thing to hear how its done its another to see. I think so many people will agree when they see it. Thanks again and again cant wait for the next

Excellent video tutorial with indexes and awesome step by step description also appropriate warnings while doing a Harmonic Tuning on the FX Crown. I took you advise and search other sites and found the information to Harmonic Tune an FX Impact. Following the information and combining it with yours, I was able to get my .25 cal. FX IMPACT shooting 25.39 gr. JSB, 910.4 FPS, ES: 6.3 FPS and SD of 2.0. Thank you taking the time to make this video and to share. Aloha, Mike

[@meatheadmarksman2013]

Nice! Sounds like you found a sweet spot with such a low es, good mv too. Thanks for watching mate!

[@stephj765RS]

Why I liked: - Essential information for those who want to tune - Straight to the point - Synthetic view - Honesty !!! You mention that you learnt from others and provide your sources of information. So many people publish stuff on the web and try to make people think that they invented the wheel.. - and the last but not least: you saved me a lot of time with this video and the links. I've been going through this whole process of tuning my Streamline 22 cal after the installation of a Huma reg. I started with a reg pressure of 120. Accuracy with speeds above 830 fps is a disaster. Group sizes from 1" to 2". What I understand now is that I'd better off setting the reg pressure at 130 bar and do all the hst tuning once again. I hope I'll be able to find a good match speed vs accuracy. Any thoughts / advices? Thanks for all the work you did and shared with us, newcomers to the airgun world :)

[@meatheadmarksman2013]

now worries mate thanks for watching! Which pellet are you tuning for? I havn't tuned a 22 yet but the factory specs are usually a good indicator of whats possible with a particular reg pressure. 130bar should be plenty. Generallllllly with pellets they are stable up to 930-940fps (depending on the pellet) so your issue with bad groups around 830fps might just be barrel harmonics, if it were going say 20fps faster OR slower the groups could drastically improve. food for thaught.

[@stephj765RS]

@@meatheadmarksman2013 22 cal. and JSB 18.13gr. I meant to say that, with the reg pressure set at 120 bar on the Huma, I'm only having groups smaller than 1" when the hst gives me ~830 fps. Above 830, groups are really bad. I used to have groups of 0.6" (avg) at 50m with the factory reg (130 bar) and ~865 fps.

[@michaelbritain5546]

Fx crown mk2 .22 fac, originally shooting 18.13 jsb at 26 fpe this dropped to 23 so thought I'd tune it up, I was looking for around 880 fps with 18.13 just over 31 fpe, after a wasted afternoon doing exactly what you did I never got the hammer maxed, took off the hammer adjustment wheel and no matter how many turns clockwise or anticlockwise the little pin that moves in and out didn't move on a NEW rifle, so after 2 wasted afternoon's at the range it's still shooting 23 fpe, an email to fx I think and yes I made sure the 1.5 mm Allen key was in correctly, great video though I'll be trying again just as soon as the problem is fixed.

[@whiskyguzzler982]

I think of reg pressure like speed of gunpowder burn and hammer spring tension and valve stem adjuster setting as how many grains of airgun “powder”. VST might be though of as a not-to-exceed setting that could allow some very fine tuning when the wheel is set to max. It’s meaningless on less than max HST settings, because it sets a limit that will not be reached. Of course it’s not exactly that simple, but once we get close to tuned it kinda is. This will mean that with a longer barrel, you are going to be expecting to need lower reg pressure and a higher hst. A heavier pellet is going to need more grains in the same barrel (+hst) and this is conveniently the thing we can easily adjust with the hst wheel. Tuning reg pressure for your heaviest pellet in your barrel and then using wheel settings for various lighter pellets, say one setting for lead and one for lead-free. Does that sound right? It seems to work that way.

[@meatheadmarksman2013]

Yeah for people who don't want to re tune every time they shoot something different I always advise to tune for the heaviest projectile at max and there will be useable settings for the lighter stuff further down on the hammer spring wheel somewhere. As for the gunpowder analogy I think an air fuel mixture might be a better way of thinking about it. Reg pressure is the fuel and the hammer spring is the air, you mix the two in a correct ratio to get explosive power

[@82HEADCASE]

Greetings Unclehodge. Great informative video easy to follow. I own a fx streamline and have not adjusted the regulator it's still at factory but I did have a go at the hammer spring tention for my own curiosity!! I got the loan of the fx chronograph and was experimenting winding in and out the tention and firing off some rounds as I went it gave me a better idea of what was going on!! Anyway I settled at a speed of 909fps for the 15.89gr jsbs I was using at the time I settled at this because the ES was the lowest iv seen only 7 most of the time I did achieve a 2 for a string of 5 shots and a 0 for 4shots but realistically it's around 7 to 10 fps !!! Would you say that the relationship between the regulator and the spring tention is a happy one!! The problem with the streamline is the reg .. no external adjustment and no way of knowing what pressure it's at so I just left it at an average of 909 fps.. now i shoot the 18gr jsb and there average is around 848fps accuracy is only on at moment because i cleaned the barrel few weeks back and have being firing surplus pellets to lead it back up agen! Look forward to reply .

[@Johnnywoo7]

Hi Uncle hodge. UK calling ! I have a Crown in 25 cal shooting 25.39 JSB. Velocity is 899 -902 ft per second. Accuracy is very good but my shot count is around 60 to 65 shots from. 250 bar fill. Reg pressure is 125 ish, power wheel is on max. Any ideas how I can increase shot count, reg pressure increase? Or hammer spring adjustment?. Love your channel you are so entertaining and very knowledgeable. Good stuff

[@meatheadmarksman2013]

That's weird... It's good speed and nicely fine tuned so you should be getting closer to 100 shots. My first stop would be to check your gauges just to make sure they are not faulty

[@Johnnywoo7]

Meathead Marksman Thanks for the reply. But how do I check if they are correct or faulty, sorry if that’s a daft question!

[@meatheadmarksman2013]

@@Johnnywoo7 that is a good question, you can swap them around and see if they read different - if you put your bottle gauge on the reg and it reads higher then your previously specified 125 bar you'll know it's wrong. They are usually out a fair way, I've had to replace mine under warranty

[@greg105]

Hi Meathead, Ive just purchased a new FX Crown MK2 and recently returned from a weekend shooting trip where we spent some time getting acquainted with each other. I was pretty impressed to say the the least. However, once I returned home from my trip I was giving it a clean and luckily noticed that the power wheel was very loose. So loose that another turn or two of the retaining screw and it would have fallen off!! Just wondering if this was a common problem with these guns? I am concerned that it will work its way loose again. Is there a way to overcome this problem? Should I take it back to my Gun shop? Cheers

[@finforcer]

Nice video sir. Can you make a detailed (closeup video) of adjusting the regulator to higher pressure? -the procedures etc.. ( My crown´s reg creeps between 125-135bar and I´d like it adjusted to 140bar. Currently after adjusting hammer JSB heavies flies at 825fps.)

[@JoePatABC]

If your reg is "creeping" you should have the reg rebuilt (spring washers and o-rings replaced). The procedure for LOWERING the original FX reg is as follows. First you MUST DEGAS the gun. That means you remove the bottle and then you shoot the gun several times to remove the residual air from the reg and the plenum. Once your gun is empty you can lower the reg pressure (I believe that is clockwise) by turning the adjustment screw in all the way. Once it's in all the way, give it one half turn back so that it is not bottomed out, you need to have some pressure flowing through the reg in order to adjust it. Screw the bottle back in and your regulator should show the new setting which will be very low. Now you will begin adjusting the reg pressure UP (counter clockwise) until you reach 100 bar. This is where you can begin your testing and HS adjustment. You can continue to adjust the regulator UP ( ONLY ) which is why I had you start at a very low pressure. Should you decide you need to lower the pressure you will have to once again degas the gun. My .25 cal Crown is set for 130 bar and shooting 25.39 JSBs at 860 fps a very stable and predictable velocity for this gun/pellet combination. Hope this helps.

[@finforcer]

@@JoePatABC Thanks for the instructions. Reg creep might also be related to faulty gauge, sometimes when tapping it gives different reading -fx´s wika made gauges are notoriously poor quality and inaccurate. (considering replacing them with huma´s)

[@dforr2981]

.... so now that I'm trying to shoot slugs in my crown, I bought both .22 and .25 slug liners, What kind of velocity should I be shooting them at? If .22cal with a 500mm barrel, what kind of Reg Pressure might I start at? and I have heard that the 23 grain Nielsens are pretty good so that is what I am using... and then with the .25 Cal, where might I start the Reg at so I can get a good velocity? So much to play with because every time you change ammo, you change settings. I thought that the .22 cal would be less expensive but they're not. The .25 cal are cheaper but not backyard friendly... I'll keep watching and thanks for he help!!

[@meatheadmarksman2013]

I havnt tuned a 22 yet so I can't really comment with any authority, I would suggest following Rolf and Gerhard from the air hunters channel on youtube and Instagram because those dude are basically specialized 22 slug shooters/tuners. As for 25 is say start as high as your comfortable with, more reg pressure is generally better especially with a short barrel. I'd run it up to 150bar and take the hammer spring through is range of motion and see where the sweet spot is, I'd expect to see 870 to 900fps, then take it out and shoot some groups

[@dforr2981]

You my friend are the best. Thank you.

[@michaelbritain5546]

So My Crown Mk2 with the amp regulator can be adjusted to increase or decrease reg pressure without degassing the gun, but the manual says increase only, to decrease degassing is required, confused 😕 er definitely, great video by the way I'm learning a lot.

[@rodrigoilabaca9419]

Hello Meathead Marksman, excellent video, unfortunately I can not understand what you are talking about, just guide me through the images ...... I have an FX Crown .25 and it is set to 130 bar and I use it in PoderMax, I use JSB King 25.4 gr and it gives a speed of 896 fps on average, it is very stable and precise. Now, I bought a Cal .22 kit and I use JSB Exact 15.9 gr that you recommend me to do when I change caliber ?, I have to modify the Bar?.

[@meatheadmarksman2013]

Test and see how it shoots before changing anything, you might find that you get good results just by changing the transfer port to 17/22 setting and using a lower setting on the hammer spring wheel. If not, fx crown from the factory comes at 115 to 120 bar reg pressure and about 18.5mm of hammer spring gap

[@theyorkshirelad.]

amazing video ive used your ideas and done my crown .30 only fault i have with this is you change your graph first graph is gone up in increments of 10 fps but second graph you show the finished graph its goin up in increments of 100 fps i think if you try the second graph in increments of 10 your line wont be as perfect not picking faults at all your video is great i watch it few times and greatfull for help just saying as ive done this and my line is perfect in higher increments than lower

[@meatheadmarksman2013]

Thanks for watching mate! I see what your saying about the graphs, I did that because I wanted the lines to all fit in the graph, the line was so messy when I first started that I had to change the scale but I get where your coming from. I also had my chronograph numbers in there somewhere so it all seemed pretty buttoned down at the time. Hopefully I'll be tuning another impact sooner rather then later and ill make another video and keep that in mind.

[@theyorkshirelad.]

Brilliant though i love watching you your interesting still playing with my crown cant seem to get any less than 5 deveation on fps

[@meatheadmarksman2013]

@@theyorkshirelad. I think this is where the impact edges ahead of the crown. If the crown had the valve overtravel adjustment you could probably squeeze that extreme spread down a bit more but when you only have a hammer spring to tune you have to move on to thing like weighing and sorting your ammo and other super fine adjustment tricks that are a bit above my level lol. In reality if your rifle is sub 10fps extreme spread you really are in the top 1% of what's possible with an air gun, or any gun for that matter so you have done a very good job

Now im ready to jump up to the mk2s and figured id see if u found a happy place for them. On a side note, did u have to mess with ur magazine to make the mk2s fit properly?

[@meatheadmarksman2013]

Nah mate I haven't needed to change the tune cos almost all my shooting is done on power 3 to keep it quiet. Its definitely doable though, if I where you I'd start at 150bar reg pressure and tune your hammer spring wheel from there. 900fps will be somewhere around 150-155bar. Just check your manual to make sure your reg can go that high. No magazine mods where needed for the mkii heavys either, just whack em in and get cracking

Hi I have had my crown for a while now it's a. 25 also. This question may have already been answered but how to do you know what is the best reg pressure for the 33gr jsb? Before you start tuning the hammer spring

[@meatheadmarksman2013]

its all about balancing speed with how many shots per fill you want to get, so if you want max speed and dont mind having to refill your gun more often youll get the highest speeds (900-920fps maybe a little less) out of 145 to 150 bar, but you should be able to get good usabble and accurate speeds like 860 to 880ish from 135 to 145bar, and then even less pressure if you decide to tune for the 25 king instead of the 25KHMKII

[@MrDirectNL]

And how do we determine the best reg pressure? Because now you just picked a random pressure of 140 bar. Maybe 130 or 135 would be enough also?

[@meatheadmarksman2013]

I used 140bar because that was Ted's suggested starting point. But in 25 cal 10 bar more of reg pressure with the correct hammer spring tune will net you about 30fps more muzzle velocity. More muzzle velocity means your shot will be affected less by external factors during flight but you must keep pellets under their maximum stable flight speed, too fast and they wobble or tumble and wont be accurate. Watch matt dubbers airgun ballistics 101 to learn more. I'll do some research and make a video about caliber specific regulator pressure choices soon

Ahhh.... another fellow Australian! Glad I found your videos! Thanks for taking the time to make them. If I had to guess, you would be a plumber? Cause you’re too smart to be an electrician! :) Love this airgun hobby of ours. Not as cheap as I first thought though... :| I’m still yet to find a cheap supply of JSB pellets in Australia so it seems.

I'm actually a bull haulage truck driver, i mostly deliver lime products with a pneumatic pressure tanker. at this very minute its 01:12am and I'm broken down at a mine site out in the Bush lol so... stay in school kids! I've been getting my ammo from Hermanns guns through shooters delight in qld

[@rachels209]

Hi guys. Greetings from Sydney. Potter Firearms is the official distributer for JSB pellets in Australia, and they deal directly with the manufacturer. Unfortunately, ‘cheap’ and JSB pellets don’t exist in Australia, something to do with being on the opposite side of the planet, plus The cost of the inspection processes at the pellet factory. The only way to reduce cost is to find a good batch number and order them in bulk, and Potter will mail order on viewing a copy of your shooters license. Less people in between helps keep the costs down. I have found them to be really good to deal with. I hope this helps fellow FX oz airheads. Dave

[@Sujaaf]

hee man i was thinking would the stock not help or change the harmonics ? after the tune ?

[@meatheadmarksman2013]

if you were to shoot it out of the stock the point of impact and group size would definitely be different, but thats not really what we are concerned with when were tuning like this, we just wanna make sure we have a nice low extreme spread and that the shots are efficient so that each round doesn't use too much air. after youve done that then you have to check how it shoots in the stock and if your group size is too big or not very consistant then you would tune again but go for around 10fps faster or slower and see how it groups

No worries mate thanks for watching! There's many a deep rabbit hole to fall down in the air gunning world...

[@theyorkshirelad.]

Brilliant can you tell me one thing about fx manual it says the reg can be adjusted from 55-160 but then says dont go above 150 yet alot of guys guns are coming from factory at 160 , my point is do you think i can go to 160 with my crown

[@meatheadmarksman2013]

if any part of your manual says don't go above 150 bar that would be my advice to stick to. FX just released a bunch of guns with the new AMP regulator that can go much higher then the generation of regulators that are in yours and mine, id be very surprised to see rifles coming out of fx with the old regulators actually set to 160bar, its much more likely that its crept up over time. the previous generation can be a little creepy, mine creeps up to 155ish if i let it sit for a day or two but returns to my setting of 145 after the first shot. generally you can get good speed out of 150 bar even with the 30cal but if you want more power have a look at the huma regulators, they are the bees knees and can go up to 190bar i think and pretty much never creep

Yeah mate I'm a Queenslander. What problems have you had with the impact?

[@gus1966]

Meathead Marksman Basically grouping in all calipers .177 .22 and .25 I have been running the H&N pellets, field target trophy have been the best so far. The other styles are all over the shop. I have had a bit of a go at tuning you have given me some ideas with the hammer spring tension which at the moment I have maxed out. Anyway a lot more homework to do your tutorial has so far been the best I’ve seen.👍

[@meatheadmarksman2013]

@@gus1966 thanks mate! If your gunna run multiple calibers without re-tuning the gun each time you switch you wanna make sure your hammer spring tension is bang on for the biggest caliber and run it much lower on your smaller calibers, experiment with the transfer port too cos that's easy to switch back. Although other ammo can be good Fx designed the standard liners for jsb ammo and they are generally the easiest to use and seem to be more consistant in weights and shape

Think im maxing out at 860 with 44gr is that good

[@darthnihilus4553]

Why taking off all of the parts from hamer spring when you can increase tension to max by puting hex key into the gap and turning??

[@meatheadmarksman2013]

Which gap do you mean mate? On mine you cant access the screw without removing the stock and you cant remove the stock with the safety and the hammer spring wheel still installed.

[@darthnihilus4553]

Maybe it is not the same as on the Impact. I watched Stivs video on Impact and he did not unscrew hamer spring wheel, it is much simpler to max out tension on Impact then on Crown.

[@meatheadmarksman2013]

@@darthnihilus4553 yeah its a little different on the crown, the stock covers up that bit.

[@westonthornton9018]

You’ll find that the FX crown loves 895 to 905 ft./s if you can find the sweet spot you should be good your accuracy will tighten Up and make sure you clean the barrel before you do all you’re turning because the barrels have polishing paste in the barrel that will rob you of accuracy

[@meatheadmarksman2013]

It took a fair few patches to get all that goo in the barrel out but I did that when I first got it. I haven't gone that high in mv yet because it's already doin so well at 870fps. When you say 895~905 do you mean with the 33gr mk2's? I'd imagine as long as you don't shoot them to fast and destabilize them you'll do well anywhere over 850ish

[@AirRifleHuntingNortSulawesi]

[@theyorkshirelad.]

Ye 150 strange ive ordered a ernest rowe hammer mod just waiting on that but cant figure why cant get higher

[@meatheadmarksman2013]

That may just be the limit for a really good extreme spread. I havnt seen an unmodified crown or impact hit 900fps in 30cal yet, it's very easy to do with a 700mm barrel but standard reg and 600mm seems to be max 890fps on the top performers

[@Pinnkong]

You still don’t know if the barrel is vibrating ! You have just optimized the airconsuption for the speed of that pellet you shoot 😉

What is the best fx impacte x fx crown ?

[@meatheadmarksman2013]

@@eldairfirmiano7181 oh okay, it depends what is more important to you. The impact has bigger magazine, can make more power and shoot bigger calibers, has picatinny rails and is smaller in size, but the crown is much cheaper and still very good. So if money is no problem go for the impact, but if you can only afford the crown you will still be very happy with it.

[@JoePatABC]

You're still shooting the gun with the shroud in the retracted (loud) position. I don't know if this has any effect on your accuracy but it definitely does on the noise level.

I think I'm gunna hve to make a video to explain this because it's seems like a very very very hard concept for some people to grasp that it's not a supressor and it's illegal for me to have one and that's why its loud.
