    If the rifle you are tuning is optimised this spring will deliver 11fpe in .177 with ease with just 34CC of swept volume and the shot cycle is supreme. Its a soft spring due to the 33 coils but packs a nice punch.

    Titan should make a copy of this one
    Re-reading this statement Tony... define 'optimised' here. I think you said it didn't work well in a TX. Just not enough room in that gun to pre-load it properly? What kind of rifle would it be good for? I ordered one of the 16J kits from Germany and I'm going to test the piston in my TX but would like to hang onto the spring if there is a good use-case for it. Maybe an HW95 at 12fpe? At 34CC would a .22 be best?

    Which of these look promising for a TX200 sub 12fpe with short stroke?

    I currently have the QX4600 - in a gun with Mk1 stroke it's up near 11.7 ft lbs with no top hat and no spacers....just custom guide. So there really is no spacing option. It would be nice to be able to adjust pre-load some more...I can't go up with this one. The piston is lightened as well.

    Here are some other Maccari springs that I can easily source here in the U.S. (some may not fit the TX factory guides though and will need custom ones):

    Only me!!!!!

    Just thought I'd ping this thread back up, to tie in with that excellent current thread on different springs and springer tuning!!

    Jim, could this go into the "Useful Info" section, yet?

    Ciao,

    As I've run out of springs for my mk2 stroke TXs, I'm going to buy a #1 and #9 titan to try, based on the info is this thread they should both be suitable. In fact I think the #1 should be perfect

    Thanks again for posting...

    I stuck a number 1 Titan in my .177 Diana 52 and it made 17 ft lb. I had to cut 3 whole coils off it to get 11.4 ft lb

    Bloomin stiff spring

    I'll be interested to hear how it goes john and how many coils you end up lopping off

    I have three sheds. Looking for a fourth...

    I want ~ 3.2mm wire, around 21 - 21.4 OD
    Coils and length is the experimentation - I want a few more coils, and a little more length, to get an overall softish but not too soft and unstable spring. I need to measure lenght, but obviously if I go a bit long it's easy enough to trim. #1 looked a good spec.

    hmmm... chopping is easy, but I don't want it too stiff... it looked less stiff than the #9 (more coils, same len), and the #9 is meant for a mk2. Maybe I should try the #10 but it looks too thin wire and possibly a bit short

    Is the #1 really stiff, or just too long ?

    Hi all

    Just thought I would add this to the mix.

    One of the guys I shoot against is running a titan No7 in his tx with good results.
    I shot it & it felt very fast but a little harsh for my liking, all other internal details he seems reluctant to divulge.
    Have any of you tried one before I waste my money.

    Regards Jon

    I tried the 9 in my set up & it made power very easily, so much so I had to cut a few coils off.

    With minimal top hat the spring has only 5mm preload which gives me 11.2-11.3 f/lb.( also gets a bit stiff to cock towards the end but not excessive )

    The number 10 had 47mm preload to make 11.2f/lb

    I use the No 9 and the Mk2 in my guns depending on stroke, the No 9 is good and makes power easily but is a bit stiff to cock, I would like something in between ideally

    I was a bit concerned that with so little preload that it would not keep the bounce in check, but it seems to shoot fine @ 25 yards, of to test it out to 55 this morning.

    Mine( TX200) has a very light piston, and that does not bounce with the No 9, I do have a bit more spring room than standard though.
