Pencil test update - B gun launches pencils now

[ArrDave]

So my 75C, when I initially installed the Cajun SRS 2 would not let a pencil leave the barrel.  Fast forward approx 500 rounds and about a year later and now I can throw pencils a few feet clear of the barrel - almost like my shadows.  Is this normal?  All I can think of is the act of firing the B gun has caused the Cajun  FPRP to warp somewhat to allow more forward movement.  

 

Anyone else experience this?

I believe the FP in CZ's warp.

Check your FP retaining pin.  My FP chewed a hole right through it  and let the FP stick out the front of the face.  I was cleaning it and noticed it and it took a bit of pressure to get it back.

As mentioned, the FPRP is worth inspecting, eventually as the Factory pin wares out it can cause issues. CGW offers an improved replacement pin. I would be keeping an eye on the primers of your fired cases as well.

This is the CGW FP and FPRP that I am having this issue with. Not excessive dry fire either and almost always with an O ring

Its sounds like you are taking the proper precautions with upgraded parts. In my CZs several of witch are set up similarly to yours i have not always found the pencil test to be a consistent measure of of good function. I tend to examine the primers of fired cases to look for signs of over-penetration. 

I am also interested to hear what other forum members have to say on the matter.
