I can only make one suggestion and it's based on experience from only one gun of this type caliber. I Ruger M77 mark II in .270 WSM and don't like the action at all. After a few total hours of working the bolt back and forth and polishing every contact point I can see it's much smoother than it was out of the box which was horrible. It appears a lot of the problem lies in the diameter of the brass being so big. Seems to make it hard for the bolt to push it forward and out of the mag well. Just seems to cause a lot more drag. Maybe it's just the way my gun is made but based on my limited experience with short mags, I wouldn't recommend one of any caliber to anybody. My gun is the first one I've ever seen, of all the deer rifles I've ever had my hands on, that was this hard for the bolt to push a round forward and get it started into the chamber. Once it pops up out of the mag well it's smooth sailing from there. I guess I shouldn't talk bad about my gun too much. I did blow the heart of doe that was about 400 yds away in half about a week ago. Never tried a shot that far before but it presented itself, I tried it and the deer is in the cooler waiting to be processed.
Anyway you might want to try the action on one before you buy it.
