    Thanks for your incomes guys =)
    And are you using solvents? (wd40 etc…)

    Ok and what do you use then?? Only pull though or any product as well?
    Also, how do you find your accuracy just after cleaning it… Spot on? Or it needs to be releaded fm with few tens of pellets ?
    Thanks for your help, again, LDP ;)

    A quick update guys !!

    So I’ve received my JSB 18.1 grains and so far, the s510 is shooting flawlessly with them !!!
    I’m having 45 regulated shots at an average speed of 900 fps and an ES of 12 fps which gives me 44 joules, just where I wanted the rifle to be.
    I shot a group of 8 pellets at 50 yards with a slight breeze: 15 millimeters wide which is good but I know I can do better.
    Yesterday I shot at my homemade steel reactive target at a disatance of 150 yards: 4 shots out of 4 hit it then I stepped down to 7 shots out of 12 again, with a bit of wind.
    The reg + the chrony + the strelok app makes every single shot completely predictable which is great for hunting purpose (that I’ve already tested).

    All in all, I think time and money spent in the installation and tuning are TOTALLY worth it, and I thank everyone who helped me out in this process especially you LDP for your wise comments and your time.

    I’ll try to shoot videos, put them on youtube, then share them here.

    That’s what I did mate.
    I put silicon oil on it.. But I found out it was a bit sticky. So I wiped it out, polished it very well with 1000 grit sand paper. Now it slides very smoothly.
    Concerning the reg, I took it out of the cylinder but I haven’t demounted it.

    Now that everything is back together, it seems to shoot fine and consistently..

    I’ve watched them mate !! ^^
    And now it seems to be okay =] I’ll keep you updated but I’m sure it’s just a matter of fine tuning and not quality =)

    And now it SEEMS TO be getting to normal with an ES of 10fps over 14 shots and an average of 918 fps… I’ve not touched anything, I’ve just waited 5 seconds between each shot.
    WTF is going on =$ =/

    Maybe I should give it few days / weeks to break in.. It’s really weird…

    Well… It hasn’t changed anything.
    Here is my last string:

    #1 934 – 927 – 925 – 927 – 924 – 922 – 922 – 922 – 915 – 913

    #2 / – 913 – 907 – 911 – 910 – 903 – 896 – 896 – 897 – 888

    #3 896 – 927 – 897 – 906 – 908 – 911 – 894 – 892 – 890 – 862

    #4 856 – 900 – 923 – / – 871 – 870 – 858 – 848 – 925 – 863

    I think I should change the spring for a slightly stronger one or ask Huma to send me a new reg…

    Ok ok…. SO as I told you, I was a bit worried by the low velocities (I was getting between 900 and 910) and the increasing ES, After the hammer weight reduction I reached an ES of 30 fps on a single with velocities jumping from 890 to 920 fps. There was CLEARLY something wrong.
    So I took everything apart even the reg which I set to 130 bars instead of 135. My guess was that, if I have less pressure applied on the valve with a lighter hammer, the valve will be opened few thousands of seconds more which will harmonise the system.
    Apparently it seems to work as I’m now reaching the 925 – 935 fps as I was before. That might means less accuracy with the 16 grains, but as I’m gonna shoot with the 18 grains soon, I’ll be in the 905 – 915 fps window which is where they seem to perform well.

    I also noticed a lot of humidity on the reg. So I cleaned the inside of the cylinder and wipe off the humidity on the reg. Regreased everything, but not too much and I’m now refilling it.

    Hopefully this will have fixed my problem. I’ll keep you informed on how it goes !!

    Yes you’re right mate… No big difference but the certainty to hit the target.
    And even if it’s a light decrease in the fps, I set a metal reactive target smaller than a hand size, at 150 yards to see if it was easier to hit it with strelok and the regged rifle…
    And surprisingly, I hit it 7 times out of 10.. So I think the issue with the 16 grains is the speed… =]

    So…
    As I told you, I was shooting between 920 – 930 fps earlier today on a string of 44 shots. That was great. BUT, this evening after the rain and with a humidity of 92%, I decided to shoot long range and see if it wqas easier to touch the target and I noticed that the velocity had decreased of 10 fps and that I was now shooting between 910 and 920 fps with the exact same setting…
    How do you explain that please? the reg breaking in? the humidity? maybe a little tiny drop of water in the reg as i fill the rifle with a handpump and that creates humidity, a lot.. Maybe something that is wrong? Maybe I should have kept the hammer at 40 grams… I’m a bit worried right now… =/

    A regulated B type wolverine mate !!!
    Dunno exactly the shot count on these but I know it’s high !! And with plenty of power..

    Yep, that’s why I’ve ordered them..
    Maybe I should set the reg to 140 bars then in order to keep the 925 fps and not going around the 900s

    I sure will enjoy it mate !!
    I’ve been stopped by the rain but here is the beginning of the last string:

    #1 928 – 929 – 929 – 929 – 927 – 925 – 924 – 925 – 923 – 924

    #2 923 – 927 – 924 – 924 – 921 – 923 – 923 – 922 – 927 – 927

    =)
    Now,I only have to sort the accuracy issues out, that’s why I ordered the 18gr jsb instead of the 16gr..
    Which pellets are you using in yours mate??

    Thanks to you mate !!! Otherwise, my rifle won’t be where it is now ^^

    I’m using the 16 grains but I’ll change.. Here a copy of a post I published on FB that explains why:
    “Do you think this choice of pellets might help ??
    I’ve noticed a significant lost of accuracy in the last few weeks with my .22 FAC aa s510 that used to LOVE the 16 grains jsb.
    Now that I’ve regulated it and obtain an extreme spread of 5 fps over 50 shots with an average velocity of 927 fps + a big service on the rifle O-rings, tightening all the screws well, barell cleaning etc etc.. I thought this problem might be fixed. Not at all. My groups at 50 are still twice the size they used to be, if not more.
    So I decided to buy the 18 grains jsb. Heavier means more power, less velocity, more stability… I’m right no?
    So.. Do you think I’ve made the right choice guys ?? =]”

    Also, I’ve RE reduced the hammer weight. 38 grams now instead of 49. Lost 10 fps but…. Well shuffed with the results mate now ^^

    Thank you soooo much for your help =)

    WellI couldn’t wait so The hammer has been under my file =)
    It weighed 49 grams now it’s at 40 grams…
    The rifle is much more silent and I assume I’ve gained 7-10 regulated shots at 935 fps that means now, I have 45 regulated shots =) with a 250 fill =)

    New string =]
    Filled to 240 bars, using jsb 15.89 grains and shim added on the hammer tail. Great results again with an ES of 11 fps but definitely too loud and air hog, only 35 shots regulated =] so I’ll buy the standard hammer and keep the FAC one intact. =]

    #1 946 – 941 – 939 – 939 – 940 – 946 –
    939 – 940 – 940 – 936

    #2 936 – 935 – 935 – 941 – 934 – 876
    (reg breaking in??) – 934 – 935 –
    943 – 934

    941 – 938 – 937 – 934

    #4 936 – 934 – 937 – 933 – (fall off the reg) – 930 – 927 – 927 – 923 – 922

    I feel this is not bad at all =)

    Ok guys now… i’m IMPRESSED with the results..
    It’s an ES of 11 fps and an average of 935 fps out of 40 shots if you take the crap ones (my fault I’ll explain) out.
    Here are the results with a fill of 250 bars:
    #1 940 – 936 – 937 – 939 – 934 – 933 –
    937 – 937 – 936 – 933

    #2 934 – 935 – 933 – 934 – 936 – 934 –
    933 – 937 – 935 – 935

    #3 / – / – 847 – 850 – 858 – 939 – 853 –
    936 – 935 – 939

    #4 851 – 842 – 844 – 864 – 929 – 846 –
    937 – 858 – 851 – 870

    #5 853 – 855 – *falls off the reg* 929
    – 926 – 919 – 916 – 921 – 915 – 910

    Now the explanation of the 8..
    Everything was absolutely fine till the 21st shot that I fired with the rifle cocked obviously but with the lever unlocked (it was forming an angle of 90 degrees with the rifle).
    So what happened ?
    I cocked, I didn’t lock the lever back, I shot and that brought the lever to its locked position but no pellet exit from the barrel, I re-cocked the rifle, Squeezed the trigger to fire the pellet that was stuck in the Barrel and I started to obtain shitty results.
    Do you have any idea why this would be??
    I hope it’ll be fixed by the refill.. I’d be so mad of I fucked the thing up after seeing what it was capable of =(

    Thanks for sharing your point of view Scott_mct =)
    I was also torn between the vulcan and cricket.. The two only reason I turned to the vulcan is the bolt placement and how it’s finished.
    I’ve read some people complaining about the cricket not having that sweet finish some other rifles have. And as I’m used to air arms, so British “superiority” in terms of quality of the chosen materials etc… I didn’t wanna take the risk to be disappointed =]
