    While i'm working on the paperpatch 38-55, I decided to pull out another old 38-40 marlin 1889 and see how its bore looked. Little better than 38-55, but note much. I'll have too shoot it too see what we're looking at.
    But this comes to mind: Since I can safely reline the 38-40 and since the 44-40 liner has the same OD as the 38-40 (Brownell catalog), couldn't I convert it to this mores popular cartridge?

    I'll freely admit I'm no expert, but I do know this: the .38-40 and .44-40 use the same cartridge case, being necked down actually from .42 (.44-40) to .40 (.38-40).

    Since the chamber is almost the same, could you have new rifling cut in the original barrel for the larger bullet?

    Yes.
    In fact I have a Winchester 1892 that went almost that route.
    It started as a .38-40, shot out or rusted out and rebored to .44-40.
    That was where it was when I bought it.
    The rebore was not well done and accuracy poor.
    So I had it lined. Since I was already tooled up for .44-40, I had it lined for that instead of going back to .38-40.
