I don't have an old or throw away scope with a 30mm tube.
The guy I spoke with at Warne explained it well and it makes perfect sense for whats hapening in the video. The bottoms tighten up to the rail just fine (Yes, I tried multiple makes of weaver rails with same results). When you tighten the top screws, there is nothing to give between the rings (solid steel lapping bar vs. hollow aluminum tube) so the bottom pulls apart the more you tighten the top screws.
I felt certain they were slipping on the base with the scope installed also but I may have been wrong or may have had the top screws too tight. Either way, after learning how the Warne rings secure the scope to the base, I am hesitant to try to recreate the problem with an expensive optic.
If the bottom screws are in tight, like farmer tight, how can they pull apart without either stripping the threads of either the base or the screws themselves or by actually bending the screws?
Do the bases themselves flex?
I need to try this for myself, as I have a few set of loose 1" Warne rings at the shop.
