I have been buying the Prvi 180 JHP ammo for $379 per case of 1000 delivered to my door from Palmetto Armory. That is under $19 per box of 50 including the shipping. I have gone through a couple of cases of it.
The amunition is made in Serbia. It shoots well and is fairly accurate in my 310 and 610 revolvers as well as my SIG P220 autoloader.
The quality really surprised me. I had made the first purchase just to get some cheap ammo to run through the MP5.
