For hunting in western Oregon, I would have a stainless barrel and action, and either a laminate or synthetic stock. For elk, I would have a .308, .270, or .30-06. I would load it with heavy Nosler partitions, or a Barnes solid copper hollow point.
Put whatever scope makes you happy, but I wouldn't go for too much magnification. If you're getting a shot on an elk, it's a pretty big animal. You're not trying to hit a little prairie dog at 600 yards here. With any of the calibers mentioned, just put the crosshairs behind the elbow, or on the shoulder, and kill it.
