One I haven't seen listed (maybe because I just got lucky with this particular scope) is the old Denver Redfield 4x. I bought it used years ago and had it on a 30-06 where it absorbed 200 grain loads for years until I had it re-barreled to 35 Whelen and it is still working great with the 250 grain loads. I'm a one rifle guy, so it gets shot quite a bit.
