Tuning .25 FX Streamline

[zx10wall]

Client wanted to shoot 60 FPE on level 3 and 32 FPE on level 1. I could do what I wanted with level 2

I really like the Streamline. Installed a Huma set to 132 bar, a Power Plenum and custom ported level 1 & 2. Very versatile platform.

Here are the results. He’s gonna be stoked.

#3 ~ 33.95gr King Heavies - 885 fps 59 FPE

#2 ~ 25.39gr Kings - 895 fps 45 FPE

#1 ~ 20.06gr H&N FTT - 845 fps 32 FPE or 16.54 gr GTO - 920 fps 31 FPE

Nice Derrick. We sold my son’s Streamline a long time ago. If there would have been after market plenums and that kind of power, we would have kept it for sure. Really liked the gun other than it was lacking in the power dept. compared to our other air guns. Nice work!

Tested the applicable pellets. The H&N FTT were a no go. However, the GTOs more than replace them. Shooting done from 40 yards. 5-shot groups pictured. Really quiet on all power levels with the attached Sumo.

GTOs at 920 fps ~ level 1:

Kings at 895 fps ~ level 2:

King Heavy MK2s at 885 fps ~ level 3:

I would love to bump the power on my 22 streamline. It would be nice to shoot the redesign out of it.
