I have a no12 hopefully on it's way, so I'll see what I'm up against when it arrives, all this short stroking is witchcraft to me, I did get some tuning advice from Jon Budd last year when I first got the rifle and he suggested getting a longer spring to help up the power, the trouble is there are so many different things that can effect power and the such and I just go by what other people who know what they are talking about, I may try a little weight in the piston first to see what that does and then muck about with the longer spring.

Well my no12 spring turned up today, it measures 300mm long and has 34 coils, so it's still different than the list but at least it fits the rear guide perfectly, that's all that matters at the moment.

Hi all,
I was talking to a gunsmith who sells and uses Titan springs and he showed me a revised list after I had problems with a no12 spring being the wrong size according to the popular Titan list that is on the internet, the list below is what has been measured by the gunsmith I talked to.
NO- OD - ID - Wire- Coils- Length
01- 21.0- 14.5- 3.2- 31- 280
02- 22.7- 15.5- 3.6- 30- 291
03- 20.8- 14.7- 3.2- 34- 304
04- 22.6- 15.6- 3.6- 28- 252
05- 19.0- 13.1- 3.0- 32- 290
06- 19.7- 13.3- 2.9- 39- 341
07- 20.0- 13.4- 3.3- 30- 255
08- 20.0- 13.4- 3.3- 34- 295

Well I've just received a no8 spring and measured the ID and it measures 13.3mm at one end and 13.4mm at the other but looking at the list, if you take 6.6mm (2 x 3.3mm wire size) of the OD of 20mm then that works out to be 13.4, so I'd say the list is wrong, I'll correct it now.
