Finally got my barrel removed (thanks for all the suggestions) and the rifling looks to be almost the same as on the replacement barrel. It is making me wonder if the barrel is really the problem.
The blish lock was wearing on one ear and I thought it may inhibit the adhersion and the bolt may be opening prematurely causing varying pressures and causing some accuracy issue. I did replace the blish lock and spring and this actually helped accuracy a bit, but definitely not what is expected.
With the barrel off and the bolt closed I would expect the face of the bolt to be centered within the opening where the barrel would fit but the face of the bolt is down a bit and you clearly see more space above the bolt and almost no space below. Do you see this too when the barrel is removed?
What other parts could be causing accuracy issues?
This weekend is the big test, a new barrel, bolt and actuator will be swapped out in the hopes I can regain the accuracy it once had.
