pcp tube

[kj]

when building a pcp should one try to hold the air tube tightly in the frame or let it have room to move as it expands and contracts. is it a bad idea to afix a band from the tube to the barrel tightly ? will a tube expand ,flex enough to affect poi ?

thanks, i'll be asking a few questions cuz i have an idea. lol. well a few. i'm searching my area for a machinist to partner up with.

I keep the tube on my benchrest rifles from touching anything else.  POI will move if you do not.  It may not move a lot....but it will move.
