Change the suppressor for another one with a different internal design in a PCP cal. 22, the point of impact will change.
FX effects of changing suppressor

Anytime you hang anything off the end of a barrel POI will change.
That is why I can't get over the concept of hanging a chronograph on the end of a barrel.
You see it all the time. Chronographs hanging off the end of a barrel.

Really? Every time I've ever hung a suppressor on the end of a barrel of an airgun, POI shifted low. I have done this many times with many airguns. So I would say , yes. That's what happens.
Including this one.

Yes that will make poi change. When done with the chrony, a couple shots with a few clicks and it’s all good.

I have several DonnyFL's & a few other brands . Every gun I've changed Moderators on have needed a sighting session.Really?

That's why I install the moderator and leave it permanently. POI is then constant. I'm not touching the moderator. For me, he is one with a gun. This is how you will keep the parameters.

I use the chronograph (FX pocket) only to set the necessary parameters and resets POI without it. To always check your speeds you have to use more expensive equipment and that's why I think of garmin xero

I have a couple of guns that the poi doesn’t change.
So not Necessarily. Most of my guns will show a change with different moderators. Depends on how well the barrel is supported. My AEAs don’t change at all My Stoegers are resistant as well

i have two moderators that i interchange between a k1 and a notos. neither of them change my POI.
i do notice a change of POI when alternating between a pellet and slug in the notos. about .25” at 30 yards. i keep my laser mounted on the notos as a point of reference for pellet impact at 30 yards so i don’t have to shoot to zero when switching from pellets to slugs. just use the turrets to match the reticle to the green dot and i’m back to my pellet zero.

Agreed , this is what I usually do. But the OP's theory is correct as far as my experience has shown. IF I switch moderators for any reason , like sound comparison , I find some deviation in POI.
