All - It was my fault -
It had nothing to do with the liner or the quality (Which is exceptional) I received a new liner today from Jim Kibler (fast and Thank you) and I started to install it - and when it started to get tight, I still saw that the edge of the liner was not "seated" in the barrel. so I backed it out, and I found out why the first one did what it did.
When I finished the hole and tapped it, I did not sink the 82 Degree countersink enough, and I "powered my way" with the first liner to make it flush, that sunk the liner deeper than it should have been, exposing the center "shaft" area of the liner and the tightening knob. I cut off the knob, and filed the liner to the barrel, but of course, I filed away the edge of the liner at the thread (which had curled up due to fitting in a tight hole) and the knob was still "proud" so I ended up with a sunken liner, and the "Halo" was the bottom cut of the liner "install" piece above the actual liner face.
When I saw the second one seated but not flush, I pulled out the liner, and set a countersink at 82 degrees with the EXACT diameter of the liner with a micrometer and mill. And Guess what, if you read the directions, and sink the countersink to the right depth, then when you screw in the liner it will touch the barrel at the exact depth and tightness expected, flush with the barrel - Imagine that?
I added 1/8 turn as Jim suggested, and easily removed the install knob.
A little flat file, and we are in business.
Jim Kibler, I owe you for one white Lightning liner, Jim Chambers, this is a perfect fit and meets exact standards. For the forum members, I owe you for a lesson learned.
I feel like the guy who took the shot just to see the Deer look up at me and say, "Nice Try" and then go back to grazing... While I spill my Powder horn on the ground.
Humbled.
The New liner installed - the proper way, following the directions.
