I built a 338-06 in 2000 on a stainless M70 action. I dinked around with it and finally sold it. Neat round, but I don't think it really offers anything over the 30-06. If I wanted more than the 30-06 I'd probably go with a 338 WM or 9.3x62. But I do get its appeal, and it is a beautiful cartridge!
