Has the quality gone up in bolt guns? I suppose that depends on the metrics one applies to define quality.
I am biased, because I own one, but I am inclined to think that at least where Savage is concerned, the quality of their bolt guns has gone up SIGNIFICANTLY since Ron Coburn took over the company.
Until recently, a Savage 110 derrivative rifle is something that I would NEVER have "stooped so low" as to even think about buying. I knew people who bought them back in the 70's and 80's and they seemed, to put it politely, very haphazardly assembled and finished, though they all shot reasonably well.
The rifle that I bought will never be considered gunmaking art like the Griffin and Howe that I once owned could claim to be. It was designed to reduce hand-fitting operations to a minimum. Yet unlike some of the 80's M-110's that I'd handled, the rifle I bought doesn't have an errant tool mark on it anywhere, or mold lines on the investment cast parts. The bore appeared to be very, very smooth. Metal was nice medium polish and practical on a hunting rifle, with bluing that seemed deeper than what I remember Savage M-110's of a couple of decades ago having.
It shoots sub M.O.A. with a host of loads. Unlike just about every Ruger centerfire rifle I've had, the bore on my Savage doesn't copper foul badly. The bolt travel is smooth and the rifle feeds reliably. Mine is a stagger-feed, blind-mag model. I would reckon that the newer center-feed versions would be just as reliable.
My Savage replaced a CZ 550 American Classic that was stolen. I thought that the single set trigger on the CZ was "the $hitzit" until I tried the Accu-Trigger at the range. I'm very impressed with the Accu-Trigger and see no need to change it. I also like the three-position safety and really like the location of it. Another thing I like is that there isn't a cocking piece beyond the rear of the bolt handle. This makes the Savage look a little goofy to some, but if you've ever shot an M-1903 Springfield with a standard LOP stock, you can appreciate the advantage of having nothing behind the bolt handle root to smack you in the face when you cycle the action while trying to maintain sight picture. Since mine is a .243 and thus a short action, the rear of the bolt stays nice and far from my face when I work the action. I think that's beautiful.
The real beauty of the Savage bolt action is in the design. It seems to me that there is a lot of engineering brilliance in it on a lot of levels and I tend to think that it was, perhaps, a little ahead of its time. The only real drawback that I can see is that the initial bolt lift effort is a little high compared to other brands.
