Got my alpha precision barrel and plenum in for my .25 P35. Should have some chronograph numbers tomorrow, I'm wondering what a difference the 23in barrel will make.
Snowpeak P35 25 cal. new barrel and plenum

Neu,
You have me watching too. I just posted on the thread I started about my 25 caliber P35 that I am up to 47 fpe with my 450mm barrel. I discovered I was not at the maximum hammer spring previously. My regulator is a bit high even with the maximum hammer spring that will cock. The brass spacer Jacques shipped with the plenum gave a slight increase versus the stock + my home made spacer at the other end of the spring. I think that is because the hammer mass is effectively increased slightly with the spacer on that end. The 47 fpe is from 850 fps on H&N Baracuda 30.86 grain pellets. You should be going faster than this. You ought to be above 240 MPS (787 fps) on JSB 33.95 grain pellets. Hopefully above 800 fps. Might even make 850 fps. (I really do not know where you will be, just guessing)

Got a chance to chronograph it today was around 950fps w/25 grain and 840fps w/34 grain @ 120 bar on the reg. I took 1 coil off the valve return spring. The last shot was off reg so it kinda jacked up the string.
I still have about one turn on the hammer but I don't want to damage the poppet till I get some more in.
Not to bad and I got 5 full mags before it dropped off the reg for 50 shots. Excuse the messy yard the leaves are killing me.

Not really just the fx pellets it shoots those extremely well and I have a bunch of them and no other .25 pellets currently.
