Not sure which rifle I'd recommend, most of them can be made to shoot well. In the less expensive models, there's a reason they are less expensive. Some of those I've heard good results from other's not so well. friend got me a mod 700 ADLyears ago that was the worst shooting rifle I'd seen in years! But lot of work rebedding the stock and it's a great shooter now, ugly as h*ll but shoots great.
As for th cartridges you choose, I'd go with the 260, better bullet's to shoot long range with. I've heard a lot of good thing's about the 6.5 Creedmore and might consider one of them if you found it. It'll give about the same ballistics as the 260 but sounds like ammo is in much better supply.
I wouldn't pick up a rifle with inexpensive scope on it unless you want it for your 22. Two best deals in my opinion are either the Redfield and the Nikon. I have two Nikons, one 4 1/2-4X and the other 3-9x, both are very good and the 3-9x was under $200. Also have two new Redfield's both 2-7x and under $200 also. I don't have a complaint with either of the brand Oh, and both are guaranteed for life!
