Greetings,
People tend to forget that the 8 x57 is easily the equal of the .30-06 when loaded to the same pressure. AR2209 is a great powder in either cartridge as long as the .30-06 is not fired in the Garand. The problem is that much of the data for the 8mm is puny as it is for many continental military cartridges.
