Yes all 3 of my Sakos have been 85's. Here's been my experience.

1. 85 Hunter 270wsm 2pc optilock lows-Occasionally hit scope when cycled slowly.

2.85 Classic 270win 1 pc optilock low ringmounts-hit scope every time.

3.85 Classic 7mmRM 2 pc optilock low/1 pc ringmounts(both used)-never a hiccup. A full fingers width clearance between case and scope.

The 7mmRM does use a longer action than the 270. Dunno if that has anything to do with it or not. Seems to me the length of the standing ejector needs to be spot on to create the proper angle of extraction in correlation to the extractor.
