SAAMI and C.I.P. measure pressure differently and their figures are not interchangeable, which is why the body is always named beside the figure.

Detail
Ruger and Hornady introduced this cartridge in 2007 to close the gap between a standard-length bolt-action and the .375 H&H Magnum, a dangerous-game round that had always needed a longer magnum-length action to feed. Dropping the traditional belt let the case hold as much powder in a shorter body: the base is held to the same diameter a belt would occupy, so the case gains the capacity a belt would otherwise have taken up, while fitting Ruger’s existing M77 rifle rather than requiring the longer M77 Safari Magnum action.
Its dimensions are set by a C.I.P. standard adopted in 2009, two years after the cartridge reached the
market, and every dimensional figure here is drawn from it. The three factory loads listed come from the
Wikipedia infobox without an inline citation to a Speer or Hornady datasheet of their own, so their bullet
masses and velocities are recorded as estimated rather than verified.
No ballistic-coefficient figure has been sourced for any of its three loads.
