Here's a pic of the operating table after the patient was sewn back up.
It appears to be recovering nicely, it's in good hands.
Hey Jason I just thought of some thing what if the barrel was moving slightly in the breech ("Then I started playing with a Ninja SHP bottle and high flow valve. Took the rifle apart a few times in the process. Accuracy went to pot somewhere along the way") I think there is just one set screw...Drill and tap for a 2nd..?

Some of the surfaces had been dressed by someone but it felt like a box of rocks. Smooth as a baby's bottom now
maybe try to lap polish a choke onto that barrel
more .177 brainstorming a thought is that if the bottle and barrel touch it could effect barrel harmonics, also could try a bit of weight towards the end of the barrel to see if it smooth's out erratic barrel harmonics? I do not know why it would happen with the .177 and not the .22 but strange things happen.
I promised an update after testing the .22 barrel today. It took only two groups, one with CPHPs and one with JSB 18.1gr to prove to my satisfaction that there wasn't something else wrong with the gun (or my donor scope).Going forward, Andy is planning to send me a sample of some .177 pellets that the rifle had previously shot well. At best, I can say at this point it is more pellet fussy than the other two .177 QB barrels I have experience with. For example, I just looked back at the initial pellet tests with my son's rifle: 10 different pellets and the largest 25 yard group was 0.81" and five of the ten produced groups under 1/2". With this 177 barrel, I'm struggling to get groups under an inch. Having now addressed several issues with the barrel, I am hopeful that Andy's pellets will fare better. We'll see.
