I've been shooting PCP's for 23 years now.
I just sold my FX Impact 25 cal after owning it for 2 years.
Things I didn't like, it didn't feed smoothly with the side shot mag/kit, and FYI, the old mag that came with it developed a cracked front lense and it quit working. I discovered that the hole that the pellet is fed through in the high cap Sideshot mag was too small so I had to sand it out to the correct size. The regulator failed twice which pissed me off until my friend fixed that issue.
This Impact had POI issues not related to scope, rings, etc, IMO it's the fragile way the barrel is attached via one set screw and that it's leaning against part of the frame, also the liner system is literally supported partially by 0-rings which I can't stand the thought of. I had a Steyr LG100 that also had the barrel leaning against the frame that had large POI shifts and it wasn't until I had the barrel free floated that the shifts stopped.
Things I did like, it was fairly accurate but not even close to my Anschutz 22rf. Being a bullpup and not having to cock the rifle under my chin was nice. Eventually I decided I just didn't like the way the gun shot off the bench compared to a regular rifle. In offhand I prefer other PCP's like the Uragan or my FX Royale.
I had a FX Revolution which was the worst POS I ever had of any gun, period! It spent more time at AOA than it did with me and in the end could not be fixed so I insisted they take it back. I got the Royale instead which has been a good rifle.
The old FX Royale was possibly their most dependable PCP, IMO.
Expensive but I think the repeater to beat is the Daystate Redwolf or Safari. Those things really shoot well, can be adjusted to different power levels, have great triggers, and have class leading cocking. It's an electronic rifle which can be considered a positive and a negative, but because it's an E system there is no spring tension to overcome when you cock it.
I went off the deep end, I ordered a Thomas HPX yesterday which is the most highly regarded PCP money can buy. I got to shoot an HPX all last weekend on Mike the creator's property and it's the total experience. That thing put down two small groups back to back at 100Y - .0" tall x 3" wide, and a .3" tall and .5" wide with 22 cal 25gr redesigns going 1003 fps!!! I also shot my highest score on a EBR target with it.
I still might get a Daystate Delta Wolf (to be released shortly) because I need a powerful repeater too but I want to make sure they don't have problems before I get one. Might just get a Redwolf for now.
