This has probably been covered herein, but here are Federal's words: see: http://www.americanrifleman.org/Webcontent/pdf/2009-11/2009111213938-federalsako.pdf

Note also, Federal's words "Specifications for the .370 Sako Mag. have been submitted to the Sporting Arms And Ammunition
Manufacturers� Institute (SAAMI). It is expected that when they are finalized, the Maximum Average Pressure (MAP) will be 62,000 p.s.i., which is the same as the .308 Win. and slightly higher than the .30-�06 Sprg., which is listed at 60,000 p.s.i."
