Seeing as high-end match ammo can go up to the $150+ per 500 range, $85/500 isn't really that bad. In fact, some would consider that "practice ammo".
Saw some of that $100 brick ammo. Cabelas in Allen is loaded with it. They had the most Norma Tac rounds I've seen there, and must have had a couple hundred 100 packs of golden bullets. The rest was pretty pricey.
