Rodger, it will some break in on the new spring before it settles down
Rodger, Have you been able to run some pellets over a chrony with the .142 spring? and how is the cocking effort?I tried several springs from .130 up to .15something in my .22 cal D56. but I don't have my chrony numbers with me at this time.I just remember anything over .135 having a worriesomely difficult cocking effort for me.
