.22 moderator caliber swap

So, the .22 can be used through a .25, but can a .25 be used through the .22. Not sure if Donny uses same moderator, for the .22 and .25
,
The air stripper in my Koi is labelled .177/.22 cal. Unscrew the front cap and see what the air stripper is labelled for caliber. It should be engraved. If not best to call them first before you try it.
 
I have a FX .22 with the Donny FL moderator. If I do a barrel swap to a .25, Can you use the same moderator for .25?
Maybe. Check the bore diameter exit hole on the moderator and call Donny FL and ask it would be compatable. I personally go up one size to eliminate potential clipping. And other words, if I am shooting a 22, I will use a 25 moderator. If I am shooting a 25, I use a 30 moderator
