Well I hunt the same areas in coastal Oregon. As many post, you likely have a shot at less than 100 yards much of the time, but then, how about that buck that stepped out of the woods across the 500yd clear cut? So for those that question 1 MOA; placing the shot where you need to place it and having the legs on the gun when you need it are worthy objectives. Having the confidence in your shooting is the most important thing to me.
I would go with the 260, of your choices. That is what my wife shoots. I think the advice about which one you shoot best with is the choice. IMHO, any of those will work and the choice of scope is as important as any of the other points made. All of my scopes have a good range in power, 2 - 10s, 3 - 15s, and a 3 -18. I dial them down when in the deep woods, but if I am sitting over a clearcut or looking across the canyon, I've got them dialed up. Good light collection is your friend on the Oregon coast during the rainy deer season.
I usually carry my 7mm Mag, because I am comfortable with it and confident I can hit what I shoot at. If it is raining really hard, I pull-out the stainless 25-06. Just setup a new Tikka 6.5 CM, expecting an antelope hunt and future mulie hunts on the east side, carrying a Zeiss V6 3-18. I will be taking it deer hunting since everything I shoot out of it is <0.75 MOA, it is cerakoted, and light. I have confidence I can hit what I aim at with it and it encompasses all of the things I like but my other two choices.
Good luck!
