That's pretty much it besides local ammo purchases and a few one time places I can no longer remember.

A few of us here try to make a road trip there every couple of months. Cheaper than shipping when buying in bulk and gives us a chance to pick up firearms they have for sale as well.

Last week or so, and then way back a number of years.

I forgot I bought two 784 rd crates of Pakistani .303 (POF) from them. They also have alot of occasional cool surplus stuff

But now I reload, so I spend a WHOLE lot less on ammo these days.

Taking back ammo due to a manufacturer's unannounced and significant design change (without a change to part number).<ul><li><a href="http://forums.audiworld.com/firearms/msgs/738.phtml">http://forums.audiworld.com/firearms/msgs/738.phtml</a></li></ul>
