I see a lot of posts talking about putting 20 or 22 barrels on 177 guns. Is there a difference in the orifaces between the 177 and 22? Or do most guns use the same one? Thinking maybe there is an optimum flow rate for each caliber.
What, me worry???
I have a pair of CFX's and one in .22 and one in.177, the transfer port is the same in both the rifles.
I also have a pair of Shadows one in.22 and one in .177 and they are also have the same size hole.
