The big problem with the Redfield style, adjustable bases is that they have very little bite or gripping surface on the ring. One good, solid impact on the scope and they can pop right out. I've seen this, so youy can't run fast enough to give me that type of base.
I've also used the old B&L adjustable mounts. They are vulnerable to damge from impacts as well and are very frustrating to adjust.
Dave Gentry makes some good, tough, windage adjustable bases. Very light, very trim and not cheap. Have had them on my .25-284 for a while now. They have survived a couple of rock bouncing falls w/o problems. E
