Strong!!!
A scope is only as accurate as its mounts, and these are far superior to the thin aluminum mounts that come standard on a Savage 10. I actually ordered these because I needed a few tenths more scope clearance and these taller mounts were way cheaper than buying taller rings. TAKE NOTE that these are sold singly, so you need to purchase in pairs; consider buying one as an extended mount to help with your ideal eye relief.

Excellent Base
A scope is only as accurate as its mounts, and these are far superior to the thin aluminum mounts that come standard on a Savage 10. Be warned that these extended bases will actually extend into the feed port of a Savage 10, but not so much that it gets in the way of loading-- I needed it for proper scope eye relief and am happy with the trade off. TAKE NOTE that these are sold singly, so you need to purchase in pairs.
