Guy's Powder Valley has a fairly good selection of powders available at this time, as well as primers for 30-06 or 308 Winchester. Bullets as well. I just put in an order to round out my supply, it will be a couple to three weeks befor it ships. I got some AA 2230 which works well in 223 and 308 sized cases as well as some IMR 7828 which is great for the belted magnums, plus 5000 CCI LRM primers and 5000 Tula SRM primers.http://www.powdervalleyinc.com/
They have always been a top notch company for me.
