That is a beautiful buck. You are in good company here.
My brother's primary LRH rifle is built on an old Rem Model 30. It has a 26" Douglas chambered in 7mm STW AI. The rifle is a lights out shooter.
Not sure what it is about those old actions, perhaps it has to do with the integral recoil lug that is part of the action. But I have noticed more than just few guys are getting great results with those "old" actions.
His rifle is nearly a twin to yours, blued action, stainless barrel.
Once again congrats and good work.
