Enysse, I think you already know you have a keeper there. I am a big fan of the current model 70. Both of my big bore bolt-action stoppers are built on this very action. Slick, and quick, to operate with dependable extraction, every time. What do you intend for sighting; open, scope, ghost/peep, halo/trijicon ? Have you dirtied the bore yet ? Happy shooting.
