The 1901 Mannlicher carbine used a proprietary Austrian load of the 7.62x25 Borchard – Mauser – Tokarev cartridge. While both then Mauser and Tokarev versions were loaded to about 1400 fps, the Borchard and Mannlicher cartridges were loaded to about 10 % less velocity. All four cartridges share he same dimensions and about 86 gr bullets.
The Mannlicher carbine has a serious design flaw, compared to the Mauser and Luger carbines: All three carbines are short recoil actions, depending on the barrel recoiling backwards on firing. On the Mauser and Luger carbines the foreend is mounted with a hanger on the lower receiver, independent of the recoiling barrel. The Mannlicher has the foreend fastened to the barrel, so it moves with the barrel on recoil. As I know from experience many years ago, gripping the foreend of a Mannlicher carbine will lead to malfunctions. If you pull back with your hand, the barrel will slide back slightly and disconnect the trigger, no blammo. If you grip the forend hard, pushing foreward, you add the mass of your arm to the recoiling parts and the gun will not function properly. So the nice foreend of the Mannlicher carbine is quite useless.
