I don't know -- the explanation I have heard is that it's more of a sandblasting effect.

By the way, the gun used in the above test has only seen limited Hodgdon H110 use (only 3 rounds since the picture w/no erosion) -- the vast majority was VV N110 (a stick powder similar to I4227 in appearance, but faster in burn rate).

Also, the blast shields that I have had replaced were eroded with A2400.

Hammerdown,

I think S&Ws bbl/cyl gap specs are pretty generous.
