Not sure what my backup will be, but the Ruger MKII .338 WM below will be my primary elk rifle this year.
The Ruger #1 in .280 Rem was blooded this last weekend, else it would have been the top candidate for the #2 spot. Might still get the job.
In terms of number of hunts and kills, though, my Ruger M77 in 7mm RM was the choice for 20+ years and never disappointed.
