Jim Sebring, an old friend and curator of the best 32-20 database, experienced this
same problem. He used a hand drill, probably an older bit for wood for an old-style
brace-and-bit, and gradually removed all six stuck bullets. He said it did not damage
the barrel , in any way. The bit should probably be just a tad smaller than the ID of
the bore, on top of the rifling.
One issue here is that you may have bulged the barrel. You can check for this
visually, just by close examination of the exterior of the barrel. You can also run your
fingers up and down the exterior of the barrel - sometimes you can feel the bulge.
Generally, if its a small bulge, it does not affect the accuracy. If its large, however,
then it can be a problem. Typically, but not always, it happens under the forged front
sight base, or over the extractor lug.
Another possibility that occurs to me, assuming that these are lead bullets, is to remove
the barrel, and melt the lead out of it. Lead melts at about 630 degress F, so if
the barrel were heated very slowly, it ought not to warp. Mind you - I have not
tried this, but as a last resort, it seems like it ought to work.
The shipping date of this gun ought to be 1917 or later. Its not 1909 - 1910.
