John:
Sorry, it's buried somewhere in one of the many threads on ballistics. The land/groove pattern is inconsistent with a standard 91/38 barrel (4 sets, at 1 twist in 8.5 inches (iirc)) and also with the cut down progressively rifled barrel (which, after cutting off the tightly wound riflings at the end, ended up with 4 sets at 1 twist in 13 inches (or something like that). The "improperly" rifled bullet was first noted by Walt Cakebread, a Navy guy, in the 1960s, but he didn't manage to interest an author in his observations until the 70's. The article that author published is in the Harold Weisberg Archives.
My own observations (with pixel counting) is that the bullet on display as CE 399 does not display the proper length / width(near the nose) ratio to be a real WCC MC 91/38 slug.
Sorry for the sketchy summary but I got to make dinner.
