I've had 27 different Savage actions, so this is my experience (the 110, 111, 112, 114, and 116 are all the same long action and the 10, 11, 12, and 16 are all short actions).
Older Savages used what they called a staggered feed magazine. Those worked pretty well with standard cases (223, 308, 30-06 and belted mag). The newer guns use a center feed design which works better for almost all calibers (I still think the 223 case works better from a staggered feed). The problem with the 6.5x284 is the rebated rim. I had a 338/284 on a Savage center feed which was a little finicky some times. If you work the action too briskly, the bolt will slide right over the small rebated rim. I've never had feeding problems using other cases out of a Savage action (from 223 up to the RUM cases)Savage made a sort of controlled round feed for a while, but I don't think they do any more. It was very close to Winchester's controlled round push feed.
I think that Savage make a great hunting rifle. They are simple, reliable, light weight, accurate, and reasonably priced. They have some pretty good specialty models as well with special stock, barrel, and caliber combinations. I have to say, the most accurate factory gun I've ever shot and the most accurate gun I've ever owned was my LRPV in 22-250. It was an honest sub .25 MOA gun which would do better than that on most days, and regularly creep in to the high .1's. I've only shot a few customs (locally) which would do better. Not bad for an $850 factory gun!
The only action I like better for a hunting gun is the Ruger 77 Hawkeye.
