Xmm JS

Because of shooter requests for 8x57mm Mauser loads that are the equivalent of ammunition currently loaded in Europe, The Accurate technical staff has developed the following data.

The European pressure limit for the 8x57mm is approximately 97% of the loading limit for the .30-06. This equates to a working pressure limit of about 58,200 P.S.I. The performance of the 8mm Mauser is excellent when loaded to its full potential. This data should only be used in rifles that have been determined to be safe by a competent gunsmith and that are known to have "JS" bore dimensions (.323" groove diameter).
