I still have two sets in use with the rear windage screws due to restrictions mandated by those rifles. Never an issue with them, but standard Talleys or now the small, neat Warne Weaver bases get most of my business. I just replaced a set of standard Weavers on a 336 and the Warnes are a bit lower, and better looking. I also had to go back to a Weaver base on my newest FN because the Warne blocked the view of the front sight through the Lyman 57. Weavers have a tunnel down the middle.
I keep an old cheap scope handy for aligning the rings. I twist the front one in with a dowel, then tweak the alignment until the scope moves freely in both rings. Burris rings with inserts are the ones I prefer for these mounts, Warne, especially Mountain Tech, for Weaver-style.
