For hunting with no real ambitions of modding, the Axis will do just fine. We did have a source of aftermarket stocks but that ended last year.
RB and Timney make triggers for pulls to around 1.5lbs so the same as the Stevens. The issue with the instock lug can be overcome
The Axis action is very similar to the Savage with far few parts. It takes similar TLC to make it run very nicely. the overal rifle is lighter then the Stevens and the det mag latch is quieter then the Savage. The more enclosed receiver is a positive to some, negative to others. Either way, less muck can fall into an Axis vs a Savage/Stevens.
My walkabout hunting rifle is an Axis 19" with a 7-08 Savage barrel. Does the job just fine. It is wearing so nicer clothes now and we see what a new barrel can do for its shooting demeanor.
The Stevens is what I use for my competition donor. Here I use the RB2 trigger and set for pull around 6oz. Barrels, stocks, rails, etc to set up for whatever I intend to do - f class, tactical, hunting, whatever.
If the long term goal is to mix and match part, the Stevens and Savage is where you want to start.
If you just want a strong durable and reliable hunting/field rifle, the axis is as good as many. I do consider the Axis the ugliest of the recent crop of plastic fantastics
also consider the ruger american. I am really liking mine and it offers lots of refinement for the money.
