7.62 x 25 ammo
seems to me that some of the surplus ammo in 7.62x25 was loaded REALLY HOT for use in one of the warsaw pact countries submachine guns. I do not remember the markings, but the info might have been posted some where here. One lot supposedly tested in excess of 46000psi. Check and be careful, due to the time lag, I suspect any of this ammo is not in common circulation, was a big controversy when I bought my VZ-52 (a number of years ago). It was one lot/production run, My local gun shop had some as well as other production runs, he researched the info after being informed from several customers and restricted the sale to those with the PP-42(?) subguns. I've always loaded my own, but had a packet of mil surp was given me that I discarded after split necks and really LOUD report and severe recoil. I routinely shoot loads with a stout charge of H-110 (max as advised by Hodgdon). that had not nearly the muzzle report or recoil.
