Hard Cocking of Sheridan Model C
 

Having most of my original air guns since age 6, I have just purchased a 1981 Sheridan Model C. As this is my first Sheridan I was not familiar with the amount of pull required to cock the bolt. Just guessing it must be on the order of 30-40 lbs and
seems jumpy during the cocking procedure. Removing the stock I don't see anything
that would create the condition, the internal components are clean and seem lubricated. Before I started to take things apart to examine for broken springs, sears,
etc I wanted to ask others their experience with the Model C.
So, anyone with Model C experience I would appreciate hearing from you....
Thank You,

Either someone has put a much stringer spring in there, or it needs disassembly. Just looking from outside won't do it. You need to get the bolt out of the gun. I would guess my C9 was maybe 5-6lbs to cock at most. Should easily be cocked with index finger.
My guess would be that either the hammer is tilting and digging into the tube or the cocking lug has worked it's way out of the hammer. (Been a while since I had my C9, but I'm pretty sure the hammer has a screw in cocking lug.
