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
The 8×50mmR Mannlicher, adopted by Austria-Hungary in 1890 as the M. 90, is a rimmed, bottlenecked rifle cartridge converted from the earlier 8×52mmR Mannlicher round. It armed the Austro-Hungarian Mannlicher M1895 straight-pull rifle and carbine, fed from Mannlicher-pattern en-bloc clips that loaded five rounds into the rifle’s magazine at once and ejected automatically once empty.
The cartridge remained Austria-Hungary’s standard rifle round through the First World War, and surplus rifles and ammunition in the calibre saw further service with Bulgaria and Italy, including use by Italy in the Second World War. It was later replaced by the 8×56mmR, for which many of the rifles were rechambered.
Case and pressure dimensions here come from C.I.P.’s published standard and are recorded as verified. Two historical ball loads are recorded from Wikipedia’s infobox, which carries no further citation for either bullet mass or velocity figure; both are therefore recorded as estimated rather than verified. No photograph of an M1895 rifle chambered for this round appears on this site.
