Call of Cthulhu alternatives

I'm a novice GM and I've been building it for Call of Cthuhlhu, but having finished a year-long campaign, I was left dissatisfied with the system (I was playing 6th ed)

It might not be the system's fault, because now I see that it was built for slow-paced "bookish"-oriented gameplay. I do not fully understand how you roleplay hours in library. And whats the point of rolling for it, really? And even if that it is, action, as I said, lacks a lot.

I was playing more of Indiana-Jones thing. The year was 1924, and Russia just few years after the civil war. Three heroes (scientists, but the field kind) are sent to the deep Siberia, where Tunguska meteorite once fell, and the Evenk people live.

And so, in the deep forests of Siberia there were too few libraries, and too much threats and cold and wind. For one, I didn't see any decent rules in how to roleplay extreme conditions. I had to come up with mine, but they really sucked just as I do. Have I missed it in the book?

Now, of course there were also extradimensional horrors, and I kind of like the sanity system, but I do not know better - so the questions is, are there better alternative mechanics?
If not, then I'll just borrow it from CoC anyway. But the combat, the shootouts, dodge mechanic, close combat - all of it is unsatisfying, even though sometimes there are exceptionally dramatic, fast and lethal moments.

Picrelated are people of Evenk, which live in those lands.

Savage Worlds

Dark Heresy

Delta Green

Nemesis. It's free! And uses the great ORE system by our saviour Stolze.

Can you elaborate, good sir? Whats the pro's and con's, if you played it.

What about Pulp Cthulhu? It is built precisely for what you describe and would be far less a learning than going to a new system would be. (Unless that is what you also want, a fresh start.)

Sounds like a neat setting/set-up.

I'd recommend Unknown Armies. Except no postmodern magick/ avatars, and free 15% skill instead of 15% Drive.
