I have owned a couple of M-19's bored sloppily enough that I could put FIRED .38 S&W cases (From a .38-200) in the cylinder! Those guns gave hard extraction with .357 ammo.

I had Roy Jinks send me the bore diameter for .38-200 revolvers and they aren't that different from .38 Spcl. Some shooters shoot .38 Spcl. bullets loaded in .38 S&W cases and report good accuracy.

I read in a UK gun magazine that the RAF had problems with jacketed .38-200 bullets ocasionally sticking in S&W barrels during shoots at Bisley. Those bore diameters are probably tighter than for Webley and Enfield .38's and the powder charge was light. I wouldn't be surprised if some .38-200 S&W's were shipped with .38 Special bored barrels, too.

I, too, think Tom is pulling our legs. If not, I bet he has a very odd gun.
