I' d go with the Tikka in .338 Win Mag. I personally can' t shoot it, but it puts a little distance between itself and the .270 Win, which a 7mm Rem Mag does not.

My ideal for elk is the .270 Wby Mag with 150gr Nosler Partitions for long-range shooting and the .338-06 with 210gr Partitions for anything under 200 yards.
