As Rob said, getting it low enough.
I'm on the crazy side of the AirForce spectrum. I add high flow tophat, regulators, plenums and large bottle on the air side. I add heavy spring and heavy hammer on the mechanical side. 18" barrel too.
I've found the H&N Barracuda Match 21.14gr were the best across a range of regulator settings. I eventually set the regulator to 1400psi and shoot the pellets at around 900FPS to maximize shot count.
With the standard SS 12" barrel it was around 2000psi for 900FPS.
My favorite regulator for the .22 is the Huben Power Cricket Max-ATH universal with the 50cc plenum.

You really only need an adjustable regulator and the power wheel to tune your gun. The rest is all for power/shot count.
I just use the small reservoir that comes with the regulator, good for 1-2 shots. Then adjust the regulator up or down 1/4 turn until you get your FPS.
A regulator with plenum will get you more shots and a much more consistent shot string.
Also, on my guns, the AirForce top hat is thread locked to their bottle. Huben Power also builds regulators with tophat. But you have to buy them from Huben Power
