 However, cases are easily reformed from the nearly identical 9.3×57mm, or the 7.92×57mm Mauser, both of which remain in production and continuing popularity in Europe.There are no unusual considerations for handloading this cartridge.Any modern bullet of .375 caliber from 235 to 270 grains will work well, although bullets that intrude deeply into the case may be undesirable due to the relatively small case volume.
