Good evening, guys!

I've been contemplating the purchase of an M1 Garand lately and I was wondering what would be the best choice for ammunition. I've been told that commercial .30-06 (Federal, Winchester, et al) is too hot for a Garand and would cause accelerated barrel-wear. Is there any mil-surp .30-06 to be had, at least any apart from the corrosive South Korean stuff I've seen on Sportsmansguide and the like? What do the Garand owners here use?

Any advice would be greatly appreciated, and thank you in advance!
