I took this off a custom Savage Model 12. It is a 25", #4 contour SS Krieger barrel with a recessed crown that was custom fitted by Jon Trammel, gunsmith, of Breckenridge, TX to a Model 12 action. I believe it to be a 1-10 twist as it shoots 88 grain Bergers real well. I wanted something that shot heavier bullets, so I took this off and put a Criterion 6.5 Creedmoor on the action. Less than 500 round count. Make me a reasonable cash or trade offer. Might be interested in comparably valued barrel for Savage 10 or 12 action.
