XS60C Hammer Spring Specs?

[pedersondev]

Hello,

Can anyone please post the specs of the XS60C's stock hammer spring?  I would prefer info for the hammer spring in the CO2 version since that is the one I will be working with.  Does the PCP version use the same spring? 

The reason I am asking this is because I need to select a servo motor with the appropriate torque for my personal project to create a electrical reloading device (like the WW1 Pederson device) for an XS 60C.

I would think that the FD-PCP uses the same spring, as the one I got was the same as a QB 7X.... The springs vary slightly in length, but once "set" are typically about 2.3" long.... They are 0.33" in diameter, and have 20 coils of 0.047" wire.... The spring rate is about 17.4 lbs/in, and when coil bound they are just under an inch in length, so have about 1.35" of travel.... The maximum force to compress it that far is about 24 lbs.... The way it is used in the QB, XS, and FD rifles it doesn't require that much force to cock because the travel is less than an inch, but they have varying preloads....
