Changing TX200 MKlll .22 barrel to .177 barrel

[mrjohns]

I would like to change my TX200 .22 barrel to .177 barrel. Is this possible, without hurting accuracy? Has anyone made this change to their TX200

A barrel change on a TX or PS is relatively easy, if the rifle is in standard form you may have to change the piston weight/tophat to maintain the power.
Accuracy should stay the same but the flatter trajectory will make shooting at anything other than zero range easier.
