I looking at get a .30 cal barrel. Just wondering if I turn the breech end to .375 for the .30 should work good. If I turn the .22 &.25 the same .375 breech end if I would get tank dump? Any thoughts?
Airforce condor barrel.

no you'll be fine unless you go down to 20 or 177 caliber.
if you need any machine work let me know..

If I understand the question, you'll have the outside diameter of the barrels set to .375 for .30, .25 and .22. You would have the breech slide inside diameter and top hat outside diameter match that .375 size so there are no leaks.
I agree with Mark, because I've paired a .177 barrel with a .25 Talon and Talon P tanks (with the .25 or "non-.177" return spring or whatever is inside the tank), and it worked fine, no tank dumps. BUT, the valve/top hat orifice was smaller than the biggest stock opening, one was the Talontunes hat with a smaller replaceable insert and the other... was just smaller, maybe .166. So... if you had your .30 set up with a huge top hat orifice (say, close to .30) and used that same orifice for .22, then I dunno, it might dump when the tank pressure got low; it would be similar to a .177 barrel on a stock Condor tank with that huge .230 orifice. So my guess is, yes it will work if you use a smaller orifice for the smaller calibers.
I think the tanks dump when the tank pressure is getting low but the pressure in the breech stays high for too long, like when a projectile gets stuck or the breech slider doesn't lock in, air leaks and the projectile doesn't leave the breech. If the breech pressure is high for too long then the low tank pressure can't overcome that breech pressure and close the valve.
