Oswald did use the correct ammo for his modified revolver. It had been rechambered from the
British .38/200 round to the .38 Special which has a slightly smaller diameter bullet. The
British .38 had a bullet diameter of .361 inches while the .38 Special is .357 inches. That .004
inch difference between the bullet diameter and the bore of the barrel prevented the barrel from
making a consistent ballistic fingerprint. The Smith & Wesson Victory Model .38 revolver was
part of a lot of 5 million produced under the Lend Lease act for British, Canadian, New Zealand,
and South African troops. After the war, these revolvers became surplus and many were put
back into the US Market. They were rechambered for the .38 Special which was a more common
ammo in the US and therefore more readily available. The other modification to Oswald's
revolver was to shorten the barrel from 5" to 2 1/2 or 2 1/4 depending on which source you
believe. After the barrel was shortened, the front sight was reinstalled on it.
Here's a website I found that pretty much sums up the history of the revolver. If I had found it
before I typed the above, it would have saved me quite a bit of time researching all of that
information.
