Power limiting consistently
I have been taking advise from many here about using shims behind the tophat to help keep the power level from going too high.

Blackops’ thread about doing this with his TalonSS is below. Much thanks to Blackops for this information leading me to try this out.

Today I found a bunch of rubber washers, 1/2″OD x 1/4″ID at the hardware store, bought a couple.
Got home and measured thickness of them, ranged from 0.071-0.063″.
My tophat is set at the factory setting, 0.093″. I put the 0.071″ one on first, it just stretched over the tophat easily.
Filled to 2800PSI, cranked the PW up to max on the Condor, and clocked 15 JSB Jumbos at 925fps – 962fps. Fastest one was right in the middle of the string. Slowest was first shot.
Tried a kodiak, and it clocked 875. Pulled the thick washer out and put in the .063″ one, and clocked 15 kodiaks at 899-955. The first shot was the slowest one.
I shot 2 more JSB Jumbos with this washer at 981 and 987fps, 2 more kodiaks at 954 and 961fps.
Preliminary testing pretty damn good, 34 shots and the bottle was only down to 2100 PSI.
I be happy with it. I have never been able to keep pellets in this range even with careful PW adjustment.
So thanks to all who suggested it, you were onto a good thing!!

Blackops, I havent noticed any blowby, but like you said mine is the newest valve.
The smallest o-rings in my picture are a bit thicker, but the “squish” factor will probably work well for heavier pellets. You might try them, I would bet the blowby wouldnt affect yhem as much.
