After all our discussions, maybe the design was made to tailor fit the slug from fx and not NS. Lighter slugs.

Power Plenum on .25 cal., 600mm slug liner and 33.5gr NS slug
- Thread starter Powerbroker
- Start date
We both made a mistaken belief that it could properly sling the 34 slugs from nielsen or a victim of ads and promos.
). Lesson here, this is a hobby and a sickness. A corona

Maybe all i want to know is if this is the same on all the PP impacts or me that is a idiot 
nobody want to talk i have ask ernest and fx usa, and gerhard, and all i want to know is, are they getting this performence with the stock power plenum, i am not asking what they did to the gun to get there, why all that secretsy, we are sopposed to help each other out right?

my problem is, that mine can’t do that even with all the mods i did, and i would like to know if they get these perfomance out of a Stock .22 impact?
but i would line to know what you did aswell??
maybe its the slugs i am currently shooting
it could be fun to see what you could get with a 25gr slug just to compair you know.

I'm not interested in 25 cal.
My mod. Stairs removed, + 27 ~ 28 fps replaced probe with snail tip +40 fps.

Absolutely no stealth modifications. you guys are not listening to anyone but Ernest.
I have many job descriptions of how things are going. Most guys on the forum tend to just ignore everything.

Now i understand my problem and your solutions. I will never get over 900fps with the stock fx and PP without machining modifications. I will just shoot pellets which i can do without PP

They are master salesmen, they have multiple youtubers all pushing there products and now scopes... whilst the FX rifles are excellent, they overhype stuff massively .
Take for example there new scopes, go buy a Sightron S-Tac and save yourself a heap..

All you need to do is open the tp hole in the probe a bit, do the same to the tp on the brass inlet but make it longer port not wider.
Maybe take a bit off the valve return spring. These mods are very well documented on the impact power mods thread. You do not need to have a lathe to make more power.

Vad, Ian & Glem, thank you for your priceless support. Have a great weekend ahead. I’ve got to burn some powder today at the indoor range.

Hi! Capitalism indeed but we need to suck it up. It is what it is.
I got me a Nikon Black FX1000. The price is competitive and the quality meets the needs of a demanding shooter.

For those who wants a better way of installing, krale has a good video. Just turn on the subtitles so you will understand. Installation with measurements. I will make one video too for everyone to share.

This is an interesting read, I have been waiting for the PP to become available in the UK so I can replace my 30cc external plenum...
My MK1 .25 700mm was shooting the 33.5 NSA's at 980fps (140b, TP and probe mod, 7mm clearance hole in valve house, 6.25 VS, standard hammer weight, gen 1 reg)
The above mods but with 600mm ST barrel shot the JSB 25.4's at 1080fps at 145b.
Not sure ill bother now....
