That .442 thing explains the weird looking engraving. I don't have that problem using felt wads under a .446, and it has proven to shoot a bunch of x's in various match, and so many in fact that more than one pretty person went home and demanded their rifle must have a problem and the gunsmith should rebarrel it...

LOL, There is always one or two of those pretty persons. That .442 is patched to bore or very close maybe just under thousand.
Don it's not just these three I have seen this several times with cork and felt, mostly cork.
I have never seen this going on with a polly or fiber wad even patched two thousands under bore diameter.
The argument from what I seen posted is that the base gets pushed forward and not the nose getting pushed back but this does put some doubt in my mind that also the nose h=gets pushed back from the looks of those bases.
But I don't like speculations so I will not sat that this is going on.
