Thats one of the problems with the 308 battlerifles these days-the ammo is getting harder to get. After the South African runs out I'm not sure what will be much available in surplus. I suggest getting it while you can.

I've also been experimenting with Russian steel case ammo in 308.
I've been using both Wolf and Silver Bear without any problems but
haven't shot that much of it. So far my HK-91, CETME, HK clones and M1A have been functioning ok.
