I have a Ruger M77R in 300WM. For 40+ years it has given me great service. Actually an unusual rifle. Very nice wood and 26" barrel (been told they only made them in 24, but this one has a 26).
Almost all manufacturers chamber their rifles in 300WM, so you have a lot to choose from. If I had to replace the old 300 today, I would do it with a Weatherby Vanguard II (shame they dont chamber it in the MK V). But that is my personal preference.
I would suggest that you go to your local gun shops and sholder a few in different makes. When you find one that feels right, then get one.
No such thing as a stupid question. What is stupid is not asking it.
