After reading the responses, I went and loaded 4 cartridges into my Sako 85 SS. No rattling until I close the bolt. I rotate the rifle tip down / tip up. With my ear to the magazine, it is definitely the cartridges. The magazine is tight. It is the cartridges that makes the noise sliding around inside. I agree, the mag. lock-up is great. I was puzzled by the rattling as well. Take out the mag. and the cartridges are tight. After insertion, they slide around. I cannot see any obvious defects. The ability to fill the magazine from the breech is a plus for me. In a scenario of grabbing the rifle from a case and loading it the quickest, the Sako wins (yes, I know one could have the T3 clip previously loaded). On the other hand, some folks say push feed actions do not have control of the round when loading. I have manipulated my T3 .270 at every angle, and with a swift shut, I cannot make the feed fail.
My summary is; all are accurate, reliable firearms. The Sako A7 is truly in between the 85 and the T3. There is no loser. Either choice will be satisfying. As far as the finnlight, hmmm. May depend upon your finances, but, the few more refinements the Sako offers will not disappoint.
