I have used Privi ammo in the following calibers 6.5x55, 7mm mauser, 8mm mauser, 9.3x57mm mauser, 303 british, 7.65x54mm argentine mauser. I've got a pretty good data base to draw upon and the factory stuff is clean, non corrosive and accurate. No problems reloading the fired cases. I even use their 286 grain soft point in the 9.3x57 mm mauser. Good accurate bullet. Some of you may recall "Hansen ammunition" back before the serbian/croatian wars. Bought a bunch mostly 7mm and swede mauser. Also have some 7.62x39 both fmj's and real honest soft point ammo. All have the NNY and the newer stuff may have a PPU stamped on the case head. Good ammo and good cases for reloading. Frank
