Yes, the M-98 Mauser is the action I use for all my own custom hunting rifles.
It's what I used for about 85% of all the other custom rifles I have made in the last 39 years too.
When you put one together right, I believe a good Mauser is about as "good as it gets" for a custom hunting rifle that MUST work every time. There are some actions as good, but nothing is more reliable.
I have sold off a great many of my rifles that I no longer hunt with, but thinking back on what I have built for myself on Mausers I can count 19 of them, not to mention a few originals I have had. Calibers go from the 25-06 to the 505 Gibbs.
I have been doing gunsmithing for 39 years now, and I am convinced that you truly can't build a bolt action rifle on anything more reliable.
Is there a specific caliber and "type" of Mauser you'd like?
