8x54mm Krag-Jorgensen
Historical Notes:
This cartridge is based on the necked-up 6.5x55mm Swedish-Norwegian military round. The purpose of this chambering was to provide an 8mm cartridge that would operate in the 6.5mm Krag-Jorgensen bolt-action rifle used by Norway. By retaining the original case, this could be done by re-barreling alone with no alteration of the action or magazine. The 8x54mm was used for target shooting and hunting and is seldom encountered outside the Scandinavian countries. It is of practically the same power as the 8x58Rmm Danish Krag military round. It could be used for almost any North American big game. It is no longer in production, and this ammunition has become a collector's item. For handloading, use bullets of .323-inch diameter.

This site and it's entities bear no responsibility for the use by others of the data included here. WARNING: For any modern firearm, it is essential that you adhere to the loading recommendations put forth in the reloading manuals of today’s components manufacturers, as well as to the owners manual of the maker of your individual firearm. The potential for things to go wrong is exacerbated in guns long out of production, those chambering obsolete cartridges, and those using cartridges containing blackpowder or cordite. As a separate caution, you must never fire any cartridge in any gun just because it looks similar to, or has a similar designation to, the cartridge the gun is chambered for. This can be extremely dangerous. Almost is not good enough, so if you are at all uncertain about the proper cartridge, have a competent gunsmith check the bullet diameter and case dimensions and firearms chamber and headspace. | |||||||||||||
