Hi

Update follows mounting the FX on my homemade support(Heath Robinson is alive and well) please see the string below, when the FX was mounted on the barrel I only got reading some of the time and they were some 630fps and some around 460fps.

as you can see from the string below with .177 Hobby's it was running at 12.4 flb so it is now apart and I will be taking out the spacers.

The gun is a new HW95 with a TBT short stroke kit and standard spring, with 10 feet to backstop
