7N6 is tough to get right now. I popped onto SG's site 2 weeks ago and they had just gotten a load in. I ordered a 1080 round spam can on Saturday and it was at my house Wedensday evening. 3 days later they were sold out. They still have some 600 round lots and 300 round lots in stock. The $139 price was a few months ago. It's $169 right now for non members. Also, it's steel cased, berdan primed, and so non reloadable like most eastern bloc ammo.
