If you have any gun shows close to you that would be a way to avoid shipping costs. Century has a flat shipping rate of $12.50 under $500 in merchendise or free over $500. Shipping tends to be a deal killer with ammo and best avoided if you can.
You can go to gun show with a few buddies and cut a deal, a pretty good deal usually.
I just wonder why we have South African 308 available but the SA 223 is no longer inported?
