co2 pressure

[angrybear]

i wonder what sorta pressure a co2 gun runs at ,
i know the capsule is about 800psi, but at the neck its a lot less, as it only about an 8th of an inch,
or the cap would blow out , so given that only a tiny squit goes into the mech , what pressure would it be using .

am i thinking to much

If the pressure inside is 800psi....Then it's 800psi, everywhere, at the base, in the middle, & at the neck.

pressure is pressure, it will equalise in whatever space it occupies.
