My first deer rifle was a "sporterized" Mosin Nagant.
Simple, sturdy, reliable, and capable of good accuracy. Slightly less powerful than the .308 Win.
Downside: No safety. Scope must be side-or "scout"-mounted. Factory hunting ammo can be expensive and hard to find. Reloading possible but a pain.
For hunting I think they best serve as a relatively inexpensive "utility" rifle of decent power and accuracy with iron sights under conditions we would not want to subject a more expensive rifle to.
