FX dreamline hammer spring tunning

[Floris]

Hey,

I was wondering if any of the fx Dreamline owners have tuned the hammer spring like the impact owners do. I dont mean turning the dail but tuning it with an allen key to get a bit more power out of the gun.

I have quite some play and shoot at the following settings:

Caliber: .22 (15 Gr, JSB Exact Jumbo)

Regulator 115

Hammer spring: Max

Temp: 10C

Speed: 906 average

This is how the gun came out of the factory but see that some owners get higher velocities.

Thanks,

Floris

i finally found some 1mm washers that i spun in the drill against some sand paper until they dropped in.

i did tune the little screw as well, to take up slack out of the slidy thing, but i don't know if that had any effect on power.

right now i am running 150bar huma reg and getting 890fps with jsb mkii 33.9gr at max power wheel.

oh wow, that is impressive. Is that the only adjustment you made? max hammer spring with allen key? Would the stock reg give the same performance at 150bar?

how many shots you get at that speed?

Only about 20, I just shoot one mag and refill, tube is at around 170bar then.

I can dial down the adjuster to get 2 mags - 32 shots - at around 810fps with the MKII 34gr.

And at 25 yards in my back yard, it is almost always one single round hole at both power levels with that pellet. By far my dreamline's favorite food.
