This is just a guess, but I suspect that the problem has to do with the
birch's fragmenting where it contacts the rifling. If that is what's
happening, you need a binding agent to hold the wood fibers together.
One thing I have seen used is a vinyl monomer diffused into the wood and
then exposed to UV to cause polymerization. The result is an
unbelieveaby tough composite that's only slightly more dense than the
wood. That's probably impractical in this case, however.
The next idea that occurs to me is a formaldehyde-phenol co-polymer
(bakelite). Dissolve phenol in alcohol to aid in penetration. Soak the
wood in the solution until it's saturated. Then allow the alcohol to
evaporate. Finally, put the wood in a 5% formalin solution.
Polymerization should occur within the wood and bind the fibers in a
bakelite matrix.
