Dad uses Grandpa's Winchester 100 in 308, after I fixed it. the bolt got jammed closed something fierce, and it took a whole bunch of persuasion to get it open after it had been sitting for a few years because nobody wanted to "wreck" the gun. Once I got it open I was able to take it apart and clean it well. I has since managed over a box of ammo without a hick-up.

Parts for them are very dear, and they tend to not be reliable from personal experience and from what I've heard. There is apparently a common alteration to the gas port to make the .cycling a bit less harsh.

I've heard it was a Winchester 100 that took the whitetail Boone and Crocket record holder.
