The titan springs always seem to need coils removing and possibly collapsing in order to fit.
Don't be fooled by hefty preload and recoil,as you said yourself removing coils can raise the power output.
Just been servicing a friends HW77.
(Graunchy cocking, dieseling etc etc.)
Did all the usual deburring, light polishing, machined a delrin rear spring guide and fitted a Titan XS no.1 spring.
It was a lot longer than the original so had to use my spring compressor to get the trigger block on, so basically I thought it may want about 3 coils cutting off.
Buzzed about 30 pellets through it then chrono'd it. definitely don't need any coils off!
It is around the 12ftlb mark, prob will rise a bit after a tin of pellets, so will have to watch it.
What do most people use for the 77 & 97 in the Titan springs?
A no.3 and cut it down? To say it was a monkey to compress, I'm surprised it didn't need cutting down.
The original spring was easy to compress and put the trigger block on by hand but also gave similar chrono readings but didn't cock nice.
I once did a HW35 with a decent spring, it was over compressed and had to cut it to bring the power up from 8ftlb to 11ftlb.
Any feedback much appreciated.

What calibre please?
A titan 13 spring cut and finished at about 29 coils would give 11fpe and a nice firing cycle.
This.
Skunky, if it's running very close to 12 I'd be reducing the length of the spring straight away and setting up for 11.4ft.lbs maximum with the pellet that the rifle's the most efficient with. This will also make subsequent removel and fitting of the spring easier, reduce cocking effort and generally reduce stress and load on all the internals.

I don’t like Titan springs in 77’s, always feel far too snappy for me personally. I prefer to use the original, massively long MK1/2 HW spring in the 25mm setups as they give a nice soft cycle.
Put on heading 270, assume attack formation

As a rough guide needs to 26 - 28 coils. Mach 1.5

Anyone ever tried the TX Mark III spring in one?
