I've got two model 70's (one 1967 and the other 1969) in .7mm and 30-06. Both shoot just fine for me and while I'll admit I'm not a long range target shooter and rarely take a shot past 300yds, I can put all of my shots in a fist (heart) sized target at 200yds with both of these rifles using simple rests (sand bag, back pack, rolled up jacket, etc...) so they are "good to go" for hunting.
Quality wise they are very good. While I prefer control feed bolts I have I've had zero problems with push feed bolt guns while hunting (or at the range). My Winchesters feed and shoot the same as any other bolt gun I have...and I've got a lot of them.
That being said I've never bought a rifle that I haven't held in my hands first......
