It's a 338 Ruger 77 mkII. I had the barrel shortened and fluted, the metal work bead blasted, the action smoothed and trigger set at 2 3/4 lbs. Then I dropped it in a take off from a Ruger Alaskan, topped it with a Zeiss 4 1/2x14x44.
this is how it started
And this is now
Longest kill with it was 475yds.
