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.
Loads
Velocity is recorded per barrel length as published. A gun page interpolates between these points and never projects beyond them.

Detail
Two cartridges wear this name and they are not safely interchangeable. The 1888 original, the M/88, used a round-nosed bullet of 8.08 mm across a bore of 0.318 inches. In 1903 the German army widened the bore to 0.323 inches and adopted the pointed S Patrone to suit it, and a modern 8mm Mauser round fired in a surviving 1888 barrel is a genuinely dangerous mistake rather than a pedantic one. The C.I.P. designation carries the distinction in its suffix: IS is the wider 1905 bore, I alone is the older one.
The 1903 change is also the reason this page carries two loads whose velocities differ by nearly sixty metres per second at similar barrel lengths. One is a military ball round designed to reach out over open ground; the other is a modern hunting load in a heavier bullet, and neither is a correction of the other.
