I might try it that way at first to see if it works (before ruining more parts than I have to). But if I like the way it works, I have an SL-68 II that will get bored as well.

Good point. I don't have experience with short barrels, so I wasn't sure if 6 inches was long enough no matter how good the fit (with a Python insert).
One of the fields I go to has paint small enough to roll out a .679 insert. A Python insert is 1.75 long, which leaves 4.25 of way over size "air bearing" for tiny paint to go through. So.... that's where my question started.
