The 8×57 JS and the rimmed version 8×57 JRS are both very flexible cartridge that duplicate the performance of the .30-06 and similar cartridges. Today not many bolt action rifles are made in 8×57 JS, but a good many double rifles and combination guns are still being chambered in 8x57JRS. However as the latter type of guns has a weaker action the loads should be reduced in order not to exceed the pressure limits.
