EZY,
If you decide to go with the Holland break, like 50Driver suggested, Darrel Holland is in Powers southwest of Roseburg. I'm not a fan of breaks but I remember my dad having Darrel install one of his breaks on a 338. Darrel picked the rifle up at a gun show in Roseburg on a saturday and returned it at the show on sunday. The break is very effective, the work was very nice and the speed, well hard to beat that.
