Working on my first Savage rebuild; purchased used with decent 30-06 factory barrel. Upon researching options for a new barrel, the 338-06 on paper looks to be an excellent candidate to upgrade for Western big game hunting. According to the tables, not much less velocity than 338 Win Mag but much more energy than the 30-06, plus potential for improved BC and SD for accuracy. Looking at this as a 400yd elk gun, I'm interested in first hand experiences with this caliber in terms of range limitation and results.
