Default Shock building

I've followed so many different ways to build shocks and I'm still having trouble getting the bladder to stay flat while screwing the cap on..
If I close the cap and the bladder moves will it let air in and intern have to redo the shock?
I'm trying to build with as little rebound as possible, any suggestions are greatly appreciated

After the oil has settled, push the piston 80% up, put the bladder on slowly, bleeding out excess air and oil, place the black plastic shock top on the bladder, then the shock cap. While threading the cap on, have one finger pushing down on the shock top to keep the bladder from moving.

That's the simplest way I've known to build em.

Would love to read more about others methods

The easiest way I've found is to get the air out, then place the bladder on top. Once you've done this, push the shock shaft up and with a 1.5mm driver gently draw a circle in the bladder so it sits down (allowing excess oil out). When you're happy, pull the shock shaft all the way down and screw the cap on. This will ensure the bladder stays seated as you put the cap on.

This method takes about ten minutes to build a set of 4.

But even when I do get the bladder seated perfect it always sounds like there's air in the shock when I compress it..
Could it be that there was a hole drilled in the shock cap to ensure no rebound and even if there's air in them eventually it'll be gone because of the hole

What shocks are these, and you certain you have the right bladders? If a bladder is too big, or swollen, they cap can cause problems, but it really shouldn't if all is right.

Top photon v2
I'm sure everything is right as far as the parts
I can get them where it feels like there's no air in them initially, but when I compress them it sounds like air is coming out of the hole that was drilled in the cap

You would expect air to come out of the hole in the cap - that's why the hole was drilled in the first place.
