I'm running DNZ on my .300 wsm extreme weather M70 with a 2.5-10-40 elite 4200 seems fine as do the multiple sets of talley LW I have just don't farmer tight them use a torque wrench. I have the Warnes on a tikka 338 federal and they seem tough as well. Been wanting to try some Burris Signature rings at some point. I like the design of the DNZ from a strength standpoint but they are the prettiest things out there. DNZ also offers a two piece set Up like talley LW . I have a set of those in 30mm on a custom 25-06......no test of recoil but they look pretty tough. Hope this helps...goodshot
