8mm Cartridges Compared
Maximum muzzle velocity comparison in % of the probably most proliferated European and American 8 mm rifle cartridges out of 650 mm (25.59 in) long barrels loaded with relatively light to heavy 8 mm bullets to their C.I.P. or SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute) sanctioned maximum pressures.
| Bullet weight gram (grain) | 8.23 g (127 gr) | 9.72 g (150 gr) | 11.34 g (175 gr) | 12.96 g (200 gr) | 14.26 g (220 gr) | Case capacity (%) |
| 7.92 x 57 Mauser (8 x 57 IS) | 100.0 | 100.0 | 100.0 | 100.0 | 100.0 | 100.0 |
| 8 x 64 S | 102.7 | 102.7 | 102.8 | 102.9 | 102.9 | 110.3 |
| .325 WSM | 108.7 | 109.1 | 109.0 | 109.3 | 111.1 | 131.7 |
| 8 x 68 S | 108.4 | 108.5 | 108.7 | 110.5 | 112.3 | 136.5 |
| 8 mm Rem. Mag. | 111.9 | 112.3 | 114.5 | 115.3 | 116.0 | 157.1 |
This comparison is not totally objective since the 8 mm Remington Magnum and .325 WSM operate at 448.16 MPa (65000 psi), the 8 x 68 S at 440 MPa (63817 psi), the 8 x 64 S at 405 MPa (58740 psi) and the 7.92 x 57 mm Mauser at 390 MPa (56564 psi) maximum chamber pressure. Higher chamber pressure results in higher muzzle velocities.

Famous quotes containing the word compared:
“The difference between human vision and the image perceived by the faceted eye of an insect may be compared with the difference between a half-tone block made with the very finest screen and the corresponding picture as represented by the very coarse screening used in common newspaper pictorial reproduction. The same comparison holds good between the way Gogol saw things and the way average readers and average writers see things.”
—Vladimir Nabokov (1899–1977)
