That's strange! Will the site allow you to browse at all? I don't remember any confirmation letter when I joined. Have you sent an email to their office? I found them very responsive and actively managing the operation of the site.
In the meantime I could approach anyone with the 404 Jeffery brass and give them your email and explain your situation then maybe we could get you connected that way.
I would suggest emailing the management and if that doesn't fix the problem I would be willing to be a go-between on your behalf.
I just went through the posts . There have been more than a half dozen lots of 404J brass sold and a bunch of ammo as well in the last four months. It's expensive and they go very quickly. I am glad to pass info along but without a doubt, your best bet is going to be to get your access squared away and check it every day. I'm sure this is no news to you, but it's a very hot commodity due to a large surge of interest in this caliber lately.
I'll try again, I've got some brass. Just scored 2 boxes off a guy here. I was shooting 400 grain hornady DGX, but hammer bullets has a 307 grain head that I'm giving a shot at. Got a box last month
