158gr not too hard to find if you keep your eyes open but the 180gr is a lot tougher. About $40 a box is average on the web sites.
I paid $60 for three 158gr full boxes at gun show earlier this year from a guy just walking around with them in his hand. He couldn't find a dealer table to take them for cash money, so I did. And I think there was a 3/4 full box of 45acp that went with it too.
Best buy was from a pawn shop / gun shop that has a $7 sticker on the box from back when they were new, and he honored it.
