For bench rest you don't want a clunky ret. A plain cross hair is nice. I would have said the Falcon T35 but it's too similar to your Weaver, maybe.
The only one I can think of that has the mag and the fine cross hair and it zooms as well is the big BSA 60.
But then again you might prefer a mildot or ticked ret for windage outdoors. In that case a big Nikko with the NATO ret.
