I haven't noticed any catastrophic quality issues with my 1995 era "classic" model 70, although I readily admit that with about 200 rounds fired, I don't know the rifle. There is a small and very strange metal thickening about halfway down the barrel. But it seems to shoot ok. Sometime, I'll send it off to PacNor, but not for a while.
I think that any of the gun manufacturers have had their quality issues, but remington definitely seems the more popular hbar, and I assume that this means that big green is good stuff. Isn't the 700 supposed to have a very fast lock time?
I have no regrets about buying the winchester.
I like the conical feed, claw extractor and longer tube on my sporter. I think that some have commented that the Winchester has a better bedding surface because of the flats underneath the receiver. Does it really matter? Apparently not. I wouldn't be disappointed with the rem 700 series.
I'd be happy with a Savage, Ruger, Sako, Mark X, BRNO or Steyr if it shot well.
