AAR on Air has a youtube out on the Remington Spirit X. In it he acknowledges that it is the Snowpeak P35X with Remington labeling. He did not seem to get a particularly accurate <12 fpe 177 but his comments in general are favorable. I've found a range of accuracy in my 3 P35s from good to excellent. His seems more at the good end. But I wonder if the new 65cc plenum is not overly large for a sub 12 177. The stock P35 plenum is under 15 ccs and seems to work fine on my 22 and 177. My 25 got a lot of velocity increase from a 35cc power plenum upgrade and I bet the Spirit X in 25 would be a powerhouse, at least for a P35. The hammer spring limits you to around 150 bar on the regulator but the P35X/Spirit X also has a longer barrel (over 500 mm versus 450 in the P35). I'm guessing 55-60 fpe in the 25 caliber. Should be capable of at least 35 fpe in the 22, possibly 40 fpe. My barrels are all choked and seem to shoot best with pellets but I have not extensively tested slugs. The P35X and Spirit X also come with a pretty nice looking wood stock. Weight it up over 6 lbs but still not terribly heavy for a PCP. Price doesn't seem to be a lot more than the P35.
Having a Remington option in this gun should also mean greater availability here in the U. S. where they are even better known than Stoeger.
