Burris Z Rings--Solid Enough?

[paul]

There seems to be a lot of difference of opinion on another forum about the Burris Z rings and weather the plastic inserts allow slight scope movement. Has anybody mounted a scope on a really accurate bench rifle using these mounts? And have you had any detectable increase in group size or any other problem with them?

I have some that I want to use on a 40x actioned 6.5-284 as I want to use the offset insert for more elevation. I am also planning on using them with my Barnard actioned 6mm Dasher but not if they have problems.
Thanks for your advice

my dad doesnt seem to have any problems on a 15lb 6.5-284

I have never heard a complaint at williamsport, FWIW.

YMMV,

There was a guy posted a pic on 24hrcampfire that had droped his rifle out of a tree stand and it bent the bell a pretty severe amount. Scope didn't shift neither did mounts. Says a lot for both.

Well, the Signatures are OK on a rifle of moderate recoil, but they won't hold an 8.5 X 25 Leupold LRT on a .338 RUM, scope eventually shifts forward after about five shots. Lapped in a set of Mk 4 rings no problem with that again.

I have a set of signatures on a 6mm AI and have no problems there.

Rust, thanks for the report. That's the first I've heard of a scope shifting with the plastic inserts. Maybe that's why Burris is now using a 4-screw clamp system on the latest 30mm Signature Zees. I've used the 1" rings on my Varmint rifles and they've been very solid.
