I own a .177 Gen2 Fortitude and am very happy with it. It shoots CPUM 10.5 grain pellets at ~750fps with accuracy of 1 moa out to 50-60 yards. Or it did when I last could shoot to 60 yards. Now I am limited to a max of about 30-35 yards and my targets (pesting) are usually between 15 and 27 yards in my back yard. There is still some room for increasing the hammer spring, but for me ~13 fpe is more than enough.
It took me a while to narrow down the problems I had with POI shifts. Turned out nearly all of them were due to me trying to alter the gun. The Fortitude has a floating barrel... that is, if the shroud does not touch either the pressure tube OR the barrel ring. Out of the box, the barrel ring was touching the shroud which I did not notice and made some, reversible, modifications to try and stabilize the barrel. The POI shifts, of course, continued. Once I removed the mods and adjusted the barrel ring to allow the shroud/barrel to actually float, I started getting my 1 MOA results.
(Early in my ownership of the Fortitude I fell victim to some stupid mod recommendations involving the shroud which nullified the floating barrel and caused POI shifts depending tube pressure. I tried to find the video(s) that recommended these mods, but apparently the person who made them took them down... due to embarrassment I am sure.)
In any case, at least the .177 version is an accurate platform out to ~60 yards (maybe more?) using CPUM pellets at ~750fps. It might be more or less accurate at higher or lower fps using the same pellet, but I have not done an extensive test to find out. 1 MOA from 25 to 50 yards is good enough for me. Especially with cheap pellets!
