Power Dial issues.

Good day,

I have racked my head against the wall until my hair has began to fall out over this – hoping one of you guys have seen or maybe another idea I haven’t thought about.

Condor with TT shroud, vented front barrel ring, and slap hammer, 2000 psi in the tank.

Dial setting 0 (as far down it would go) JSB 25.39 grain – speed 1050s maybe 5 fps sd over 10 shots. About 150# air drop.
Dial setting 12 (as far up as it would go) JSB 25.39 grain – speed 1050s maybe 5 fps sd over 10 shots. About 150# air drop

Charge to 2500#
Around 1100 fps on both at highest and lowest.

Shift back to factor hammer:
Seeing about the same as with TTSH.

Tried 43 grain pellets – 908 fps.

Now the interesting part….
Swap tanks 2400# factory hammer. 900 fps with 25.39 grain and 853 with 43 grain… dial setting have no influence.

Ugg…

Thanks for any help,

Kendall
