#1 you gotta figure out what's your purpose for the rifle. this is critical. if you want something for precision or target and you end up purchasing a good hunting rig, there's no way to convert. you're kinda stuck.
#2 decide the chambering. the selection of chambering is more important than the rifle. if it's a target rifle, I personally do not see much use for .308 or even higher. To 300 yards I find .223 more than capable for fun at the range, and far cheaper. I do like .308 but for me it's for hunting or to buck the wind better at 400+ yards.
#3 decide on your optics. the best rifle in the world isn't worth shit unless the optics are quality
personally my favorite bolt action rifle is the Ruger American Ranch .223. I like it so much the .300 blackout is on it's way too. 16" barrel, very light and handy, threaded barrel, weaver rail installed, triple lug bolt for nice short throw. it's basically ready to rock and roll and stupid accurate.

I am very partial to the 7.62x39 cartridge due to its low cost and nice intermediate power while still giving that .30 caliber shwak on the steel. If you also like this chambering then consider the CZ 527 or a zastava M85 either in 7.62x39. The CZ 527 in 7.62x39 is an all time favorite of many shooters.
