Except for their match 308 and 6.5x55 ammo, one should not expect really good accuracy out of their ammo. Mind you, should do OK for your general purpose hunting/plinking. I've shot a fair amount of Prvi ammo and never a problem with any of it....all chambered well and fired.
Been using Prvi brass for reloading various cartridges for over 6 years now. Consider it pretty decent. Pick up a lot of brass at range I'm a member and most of the time I keep any Prvi brass I've found for reloading. Generally get a fair amount of reloads out of it. Very seldom have a problem with primer pockets loosening. Every once in awhile have had some that brass was on the hard side, so had to anneal it sooner than I normally would.
Recall an inquiry not that long ago on some gun site about Prvi brass. All replies were positive about Prvi. One of replies was from a guy who carefully checks all his new brass: weights them, checks necks to see it they need to be turned and etc. Basically his comment was, "its been consistently good"....recommended using it.
