The new scope is a matte black, Leupold VX2, 3-9x, wide duplex. I like the greater width of the fine crosshairs that it offers.
I'm using my old standby, four-screw Weaver matte rings with weaver bases. The four screws prevent torque on the tube, common with two-screw rings. (The rings were back-ordered, so used a new pair of the two-screw, high rings that I had.) I bore-sighted the scope as close as I could, compared with my other .270, so I'll try to shoot it today and see how close it is on paper.
I thought of getting fancy mounts, but think a lot of them are bulkier and way more expensive. Why mess with success? I've used them on my rifles and customers' rifles, even on my benchrest scopes for over 55 years and they've never failed me. I can't say that about other systems that look like Weavers.
Other good news is that reloads fit both of my Rem .270s.
