My .25 Stormpup was set up in the 65 FPE range for hunting and my .22 was set up in the 35 FPE rang for backyard work, after Wednesday's hunt I decided to reverse the roles.
So I took the weak spring out the .22 and put it in the .25 Stormpup, I than set up the .22 with the stronger spring for Hog Hunting next week.
The .25 Stormpup has a Transfer port adjustment too but I did'n even Bother to mess with that.



Filled the Stormpup to 150 BAR and this is the string with the JSB 25gr pellet, down to 90 BAR

Perfect to me for Backyard control
not to mention those JSBs are outstanding in the accuracy department,...I still have a tin of Predators so I think O'll use that one up.
The .22 is set up in the 55+ FPE for next Wednesday hunt
