I got a letter from Ted Curtis at Accurate. They tested various military 7.62x25mm ammo for pressure. They tested:

"ammo from China, Russia, Austria, Bulgaria, and the Czech Republic. Commercial ammo produced by Sellier and Berloit was also tested. Based on these test results we arrived at a maximum pressure for our load data of 42,000 C.U.P. Only the single lot of Russian ammo was signifigantly below this pressure averaging 32,000 C.U.P. The consisant pressures between all other types and manufacturers was a welcome surprise. Indeed, the fact that Czech ammo, made for the CZ52 pistol, produced the same pressure as that of the other countries was perhaps the biggest surprise of the whole project. This inspite of the 'tribal lore' regaurding this particular handgun and ammo loaded for it claiming that shooting Czech ammo in any other firearm so chambered will cause spontainious dissassembly. The presure data produced by the ammo tested certainly doesn't support this theory."

The 1913 fps AA#9 loads Accurate sent are now published in "Accurate #2" load book.
