nsaqam,
The reason a lot of people have mentioned Talley Lightweights despite the OP saying he wants steel is because they know his assumption that aluminum mounts are ALWAYS weaker than steel is BS.
I have also run into a bunch of people who firmly believe one-piece steel bases are far stronger than 2-piece bases. This isn't true, because 1-piece bases typically use 3 screws, while 2-piece bases use 4 screws. And the screws are the weak point of any scope base.
Similarly, a mount system that does away with the base/ring connection is stronger, whether the connection is avoided by attaching the rings directly to the receiver (as in Ruger and CZ) or attaching the bottom of the ring directly to the receiver, as in Talley Lightweights.
