I recently found that the 14th edition of Cartridges of the World is available online through Google Books. The 458x1.5" is described on page 323. This link may take you to that page, or pretty close: COTW #114. Your might have to scroll up or down to find the listing. The next page, page 324, has some loading data, which looks pretty mild.

Page 522 has the write up of a shortened 458x1.5" being used in Vietnam, the modified cartridge was designated the 11.63x33.


Bob, thank for the link. Once it cools down some, I' will play with H4198 on paper and chrono some loads. I was using it and 4227 for function and break in loads with 350gr bullets, recoil was a little stiff but tamed down a good bit with the brake.
